We continue to follow the U.S.-Canada trade dispute, in the context of the changing global trade situation, and will continue to update the following as required. This new post updates the situation to include (i) the most recent U.S. Executive Order signed on July 31, 2025 increasing the tariff rate on products of Canada from 25 percent to 35 percent, which went into effect as of August 1, 2025, (ii) the U.S. Proclamation issued on July 30, 2025 imposing a 50 percent tariff on semi-finished copper products such as pipes, tubes, wires, sheets and rods, (iii) the increase of the rate of anti-dumping duty applicable to Canadian softwood lumber to 20.56 percent, and (iv) the implementation, by the Government of Canada, of tariff rate quotas (“TRQs”) on imports of steel mill products.
At the 2025 G7 Leaders' Summit held in Alberta on June 15-17, a 30-day trade deal deadline (i.e., July 21) was set between Canada and the United States. However, negotiations almost derailed at the end of June, and Canada was forced to repeal its digital services tax to resume trade negotiations with the United States.
Topics Discussed in this Post
This post is divided into five sections:
- Chronology of the trade dispute;
- S. tariffs on Canadian goods (updated);

- The America First Trade Policy.
Chronology of the U.S.-Canada Trade Dispute
The U.S.-Canada trade dispute can be traced to President Trump’s first day in office, January 20, 2025. On that date, an Executive Order known as the America First Trade Policy (the “Policy”) was issued. Described in greater detail at the end of this post, the Policy sets out the U.S. administration’s desire for:
“…a robust and reinvigorated trade policy that promotes investment and productivity, enhances [U.S.] industrial and technological advantages, defends [American] economic and national security, and – above all – benefits American workers, manufacturers, farmers, ranchers, entrepreneurs, and businesses.”
On February 1, 2025, an Executive Order was issued (the “Fentanyl Order”) to officialise the imposition of the tariffs against Canada. President Trump declared a national emergency under the U.S. International Emergency Economic Powers Act (“IEEPA”)and cited the “sustained influx of illicit opioids and other drugs” coming from the Canadian border to justify the action. After being postponed for 30 days, purportedly to allow the two countries to negotiate border security matters, the tariffs finally came into effect with the White House’s March 2, 2025 announcement that, effective on March 4, 2025, the United States would start levying a 25 percent tariff on almost all goods imported from Canada, with a lower tariff of 10 percent applicable on Canadian energy and resource products such as crude oil, natural gas, lease condensates, natural gas liquids, refined petroleum products, uranium, coal, biofuels, geothermal heat, the kinetic movement of flowing water, and certain critical minerals.
Four days later, on March 6, 2025, another Executive Order was signed by the U.S. President “[i]n order to minimize disruption to the United States automotive industry and automotive workers” (the “March 6 U.S. Order”). The March 6 U.S. Order effectively had the effect of removing all tariffs on goods that are imported into the U.S. free of duty as a good of Canada pursuant to the Agreement between the United States of America, United Mexican States, and Canada (“CUSMA”). The March 6 U.S. Order was effective with respect to goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. EST on March 7, 2025. The March 6 U.S. Order also announced that the additional tariff on Canadian potash (that is not subject to duty-free treatment under CUSMA) was reduced to a rate of 10 percent.
Subsequently, as of March 12, 2025, two other presidential executive orders officially reinstated a 25 percent tariff on Canadian steel imports into the United States and Canadian aluminum products. These additional tariffs were immediately met with Canadian countermeasures on $29.8 billion of U.S. steel and aluminum products and other goods including computers, sports equipment and cast iron products, which took effect on March 13, 2025. The goods affected by these countermeasures are notably among those that were listed as targeted products in the second phase of Canada’s response to the U.S. tariffs.
In response to the entry into force of the Fentanyl Order, Department of Finance Canada immediately enacted previously announced countermeasures and imposed 25 percent tariffs on $30 billion worth of goods to take effect on March 4. As a second phase, an additional $125 billion worth of tariffs were to follow within 21 days following a public consultation. However, the Canadian government has since put such second phase on hold in response to the partial lifting of the U.S. tariffs as announced in the March 6 U.S. Order.
On March 25, 2025, President Trump issued a new proclamation whereby all imports of automobiles and automobile parts would be subject to a 25 percent tariff. Such additional tariffs came into effect on April 3, 2025 for automobiles, and subsequently, on May 3, 2025 for automobile parts.
On April 2, 2025, the U.S. President’s so-called “Liberation Day”, another presidential executive order (the “April 2 U.S. Order”) established reciprocal tariffs with a baseline rate of 10 percent (the “Baseline Tariff Rate”) on imports from every country effective as of April 5, 2025. However, the actual tariff rate applied to many countries temporarily exceeded the Baseline Tariff Rate, with such higher reciprocal tariffs applicable to certain countries (as determined on a country-by-country basis) being suspended for ninety days, effective as of April 10, 2025. Importantly, however, the April 2 U.S. Order provides for exemptions related to Canada, which are discussed in further detail below.
On June 3, 2025, by way of a new proclamation (the “June 3 U.S. Proclamation”), the U.S. government has increased the tariff rate on imports of steel and aluminum products from Canada and most other countries from 25 percent to 50 percent, effective as of June 4, 2025. The June 3 U.S. Proclamation has also changed the previously established tariff stacking order in respect of certain U.S. tariffs which, from a Canadian perspective, had the effect of limiting the availability of the exceptions discussed below in respect of certain products of Canada that satisfy the CUSMA rules of origin.
On July 25, 2025, the U.S. Department of Commerce also announced that effective on that date, the anti-dumping and countervailing duty rate applicable to Canadian softwood lumber imported into the U.S. from most Canadian companies would increase from 14.5 percent to 20.56 percent.
On July 30, 2025, a U.S. Executive Order (the “De Minimis Exemption Order”) was issued providing that, effective August 29, 2025, all imported goods shipped to the U.S. (other than via the international postal network) and that are valued at or under $800 would no longer qualify for the so-called de minimis exemption and will therefore become subject to all applicable duties.
On July 30, 2025, another U.S. proclamation (the “Copper Proclamation”) was issued providing for, effective as of August 1, 2025, the imposition of 50 percent tariffs on copper pipes, wires, rods, sheets and tubes, as well as certain derivative products such as pipe fittings, cables and electrical components.
On July 31, 2025, President Trump amended the Fentanyl Order through a new Executive Order (the “Amended Fentanyl Order”) in response to Canada’s alleged failure to cooperate in stopping the flow of fentanyl and other illicit drugs across the border and also due to its trade retaliation against the United States. The Amended Fentanyl Order has increased the tariff rate on products of Canada from 25 percent to 35 percent effective as of August 1, 2025.
With the objective of minimizing the impacts of this trade war on their respective economies, both Canada and the United States have implemented measures providing relief from certain newly imposed measures, which are discussed in greater detail below.
U.S. Tariffs: Implementation and Implications (Updated)
History
Contrary to a widespread belief, this is not the first time that President Trump has imposed tariffs on Canadian goods exported to the U.S. During his first mandate, the U.S. administration ultimately imposed tariffs on imports of steel and aluminum products from Canada at rates of 25 percent and 10 percent, respectively (this followed proclamations signed by the President on March 8, 2018, imposing tariffs on all steel and aluminum products imported into the U.S.). Those tariffs took effect on June 1, 2018, upon the lifting of the temporary exemption that Canada had initially been granted.
Although Canada proceeded to impose retaliatory surtaxes on multiple U.S. products imported into Canada, it took almost a year to end this first real trade war with Canada’s largest commercial partner in the era of U.S.-Canada free trade (which dates to the 1989 Canada-U.S. Free Trade Agreement, which as followed by the 1994 North American Free Trade Agreement (NAFTA), and then by the 2020 Canada-United States-Mexico Agreement (CUSMA). Although narrower sectoral trade disputes between Canada and the United States are not uncommon (the softwood lumber dispute is a good example), the 2018-19 U.S. -Canada trade war was by far the broadest conflict – until 2025.
In this context, the entry into force of the Fentanyl Order on March 4, 2025 could be considered as the “declaration of war” in a second major trade dispute with Canada, the casus belli of which is that Canada (like Mexico) has allegedly failed to strengthen border security to deal with the opioid crisis. In previous declarations, the U.S. President has also stated, at various times, that illegal border crossings by migrants and what he believes to be a significant U.S. trade deficit vis-à-vis Canada are also important issues for the U.S. With Canada’s immediate reaction, this has become a full-out battle.
25, 35 or 40 percent duty (products of Canada)
Section 2(a) of the Fentanyl Order provides that: “all articles that are products of Canada as defined by the Federal Register notice described in subsection (e) of this section (Federal Register notice), and except for [Canadian energy or energy resources], shall be, consistent with law, subject to an additional 25 percent ad valorem rate of duty.” The Notice published by the U.S. Customs and Border Protection (“U.S. CBP”) in the Federal Register notes that the test to determine what goods constitute “products of Canada” include both goods of Canada under the CUSMA rules of origin as well as goods for which Canada was the last country of substantial transformation prior to importation into the U.S. (i.e., the “substantial transformation test”).
The 25 percent duty rate was applicable with respect to products of Canada entered for consumption, or withdrawn from a U.S. warehouse for consumption, from March 4 to July 31, 2025. Pursuant to the Amended Fentanyl Order, effective as of August 1, 2025, the tariff rate on products of Canada has increased from 25 percent to 35 percent. Goods qualifying for preferential tariff treatment under the CUSMA continue to remain exempt pursuant to the March 6 U.S. Order. Furthermore, the Amended Fentanyl Order also provides that goods that are being transshipped to potentially avoid the 35 percent tariff will be subject to a higher tariff rate of 40 percent.
U.S. CBP is responsible for collecting the duty upon importation.
10 percent duty (energy and energy resources)
Section 2(b) of the Fentanyl Order further provides that:
“[w]ith respect to energy or energy resources, as defined in section 8 of Executive Order 14156 of January 20, 2025 (Declaring a National Energy Emergency), and as otherwise included in the Federal Register notice, such articles that are products of Canada as defined by the Federal Register notice shall be, consistent with law, subject to an additional 10 percent ad valorem rate of duty.”
Section 8 of Executive Order 14156 defines the term “energy” or “energy resources” as follows:
“crude oil, natural gas, lease condensates, natural gas liquids, refined petroleum products, uranium, coal, biofuels, geothermal heat, the kinetic movement of flowing water, and critical minerals, as defined by 30 U.S.C. 1606 (a)(3).”
As it is the case for other “products of Canada,” the 10 percent duty is applicable with respect to Canadian energy or energy resources imported on or after 12:01 a.m. EST on March 4, 2025.
Again, the U.S. CBP is in charge of collecting the duty.
Exemptions
We understand that narrow exceptions might include personal communications, certain donated articles, informational materials, and transactions ordinarily incident to travel.
There is also an exception for goods eligible for duty-free de minimis treatment under 19 U.S.C. 1321, i.e., shipments valued at less than $800. However, pursuant to the De Minimis Exemption Order, such exception would no longer be applicable as of August 29, 2025.
Additional tariffs
Section 2(d) of the Fentanyl Order provides that in the case of Canada’s retaliation against the U.S. tariffs, the President may then increase or expand in scope the tariffs imposed under such order. The Amended Fentanyl Order notably cites such reason to increase the tariff rate on products of Canada from 25 percent to 35 percent.
The March 6 U.S. Order
The March 6 U.S. Order effectively had the effect of removing all U.S. tariffs on products of Canada that satisfy the CUSMA rules of origin. The March 6 U.S. Order is effective with respect to all goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. eastern standard time on March 7, 2025.
The March 6 U.S. Order also provides for a reduced 10 percent tariff on Canadian potash imported from Canada that falls outside the CUSMA preferential treatment.
Therefore, effective as of March 7, 2025, the U.S. CBP only collects additional tariffs on products of Canada that do not satisfy the CUSMA rules of origin (using, as of August 1, 2025, a 35 percent rate for most products and a lower 10 percent tariff on energy products and potash). However, this relief measure is subject to two exceptions: first, Canadian automobiles satisfying the CUSMA rules of origin are subject to a 25 percent rate of duty on their non-US content as of April 3, 2025, second, effective as of June 4, 2025, Canadian steel and aluminum products that qualify under CUSMA are also subject to a 50 percent tariff.
Other U.S. announcements
Section 232 tariffs on steel and aluminum
In an apparent disavowal of the Joint Statement by Canada and the United States on Section 232 Duties on Steel and Aluminum entered into in May 2019, the U.S. President signed two executive orders on February 10 and 11 which cancelled all exemptions to section 232 tariffs on steel and aluminum imports, including previous exemptions granted to Canada. The two executive orders reinstated a 25 percent duty on all steel imports and also raised tariffs on aluminum from 10 to 25 percent. As mentioned above, these additional duties took effect on March 12, 2025.
Subsequently, the June 3 U.S. Proclamation increased the tariff rate on steel and aluminum products imported from Canada and most other countries to 50 percent. This tariff rate increase was accompanied by certain modifications to the previously established U.S. tariff stacking order such that the exemptions made available on March 7, 2025 for imported goods that qualify as originating goods under the CUSMA are no longer applicable to Canadian steel and aluminum products.
Reciprocal trade and tariffs
On February 13, 2025, the U.S. President signed a Presidential Memorandum requiring the implementation of a comprehensive plan for allegedly “restoring fairness in U.S. trade relationships and countering non-reciprocal trading arrangements”. Such plan, called the “Fair and Reciprocal Plan”, is designed to pursue two main objectives: (1) reducing the U.S. annual trade deficit in goods, and (2) addressing what are perceived as unfair and unbalanced aspects of U.S. trade with its foreign trading partners. Canada’s digital services tax imposed on American companies, the goods and services tax/harmonized sales tax imposed on importation of U.S. goods into Canada, as well as the large duties imposed on “supply-managed” products, such as dairy, have notably been cited as “unfair” Canadian measures against the U.S. In practice, the April 2 U.S. Order did not actually impose additional tariffs on products of Canada, as they are already subject to previously issued executive orders, as discussed above. In fact, the April 2 U.S. Order may even lower the tariffs on Canadian goods in the event that such earlier executive orders are terminated or suspended. The key points are as follows:
- As a reminder, all goods of Canada that do not qualify as originating under CUSMA (except for steel and aluminum products, as discussed above, and for automobiles, as discussed below) are currently subject to an additional ad valorem tariff of 25 percent, while energy or energy resources and potash imported from Canada and not qualifying as originating under CUSMA are subject to the lower additional ad valorem tariff of 10 percent.
- Pursuant to the April 2 U.S. Order, any ad valorem rate of duty on articles imported from Canada under the terms of that Order will not be imposed on top of any ad valorem rate of duty specified by an earlier U.S. Order. (In other words, the rate of duty will remain the same as it was under the earlier U.S. Order.)
- On the other hand, the April 2 U.S. Order also provides that if the earlier U.S. Orders are terminated or suspended: (i) items from Canada that do not qualify as originating under CUSMA will be subject to an ad valorem rate of duty of 12 percent (rather than higher tariff rate); and (ii) ad valorem tariffs on articles imported from Canada shall not apply to energy or energy resources, to potash, or to an article eligible for duty-free treatment under CUSMA that is a part or component of an article substantially finished in the United States.
Section 232 tariffs on copper and the Copper Proclamation
In an Executive Order signed on February 25, 2025, the U.S. President asked the U.S. Secretary of Commerce to initiate an investigation under section 232 of the Trade Expansion Act to determine the effects on national security of imports of copper in all forms. Within 270 days of this order, the U.S. Secretary of Commerce will submit a report to the President, together with recommendations on actions to mitigate such threats, including potential tariffs.
Note that pursuant to the April 2 U.S. Order, copper shall not be subject to the ad valorem rates of duty provided for under such order.
On July 30, 2025, the Copper Proclamation was issued, imposing effective as of August 1, 2025, 50 percent tariffs on copper pipes, wires, rods, sheets and tubes, as well as certain derivative products such as pipe fittings, cables and electrical components imported into the U.S. Although an exemption for Canada has not been announced yet, the Copper Proclamation excludes multiple copper products that Canadian exporters ship to the U.S. such as unrefined copper, copper alloys, copper cathodes and anodes, and copper waste and scrap.
Section 232 tariffs on automobiles and automobile parts
As previously mentioned, on March 25, 2025, President Trump announced that all U.S. imports of automobiles and automobile parts would be subject to a 25 percent tariff, with such ad valorem tariffs entering into effect on or after 12:01 a.m. EDT on April 3, 2025, for automobiles, and subsequently but no later than May 3, 2025, for automobile parts.
Importers of automobiles under the CUSMA have the opportunity to certify their U.S. content such that the 25 percent tariff only applies to the parts of the automobile that are not American-made. Furthermore, the Proclamation also provides that the ad valorem tariff of 25 percent shall not apply to automobile parts that qualify for preferential treatment under CUSMA until such time as a calculation method is established and a notice is published in the Federal Register.
The De Minimis Exemption Order
The De Minimis Exemption Order signed on July 30, 2025 provides that, effective August 29, 2025, all imported goods shipped to the U.S. (other than via the international postal network) and that are valued at or under $800 would no longer qualify for the so-called de minimis exemption and will therefore become subject to all applicable duties. For goods shipped through the international postal system, duties will be assessed under two possible methodologies based on the value of each package including an ad valorem duty methodology that will become mandatory after six months.
Softwood Lumber
The U.S. Department of Commerce announced that as of July 25, 2025, anti-dumping and countervailing duties applicable to imported Canadian softwood lumber increase from 14.5 percent to 20.56 percent with respect to most Canadian exporters.
Relief Measures
On April 29, 2025, President Donald Trump signed an executive order (the “April 29 U.S. Order”) addressing certain tariffs on imported articles. The objective of the April 29 U.S. Order was to avoid the cumulative effect of overlapping tariffs on certain imported articles by setting out the procedure for determining which of multiple tariffs shall apply to the good in question.
On the same day, President Trump also signed a proclamation to incentivize domestic automobile production under which a portion of tariffs for imported automobile parts used in U.S.-assembled vehicles could be offset. The maximum tariff reimbursement for the year beginning on April 3, 2025, and ending on April 30, 2026, is 3.75 percent of the value of domestically produced cars. This cap will decrease to 2.5 percent the following year and will be phased out entirely thereafter.
Canadian Countermeasures (Updated)
First phase (effective March 4, 2025)
The Canadian protective measures were originally designed to be implemented in two separate phases. The first phase includes 25 percent tariffs (also called surtax) on $30 billion in goods imported from the U.S. and is effective as of March 4, 2025. The list of targeted goods is quite broad and includes a variety of goods produced in the U.S. such as:
- orange juice,
- peanut butter,
- wine, spirits and beer,
- coffee,
- appliances,
- apparel and footwear,
- motorcycles,
- cosmetics, and
- pulp and paper.
The approach adopted by Canada is similar to the measures that were implemented by Canada during the 2018-19 trade war although the current list of targeted goods are broader.
According to the Backgrounder published by the Department of Finance, only goods “considered as those goods eligible to be marked as a good of the U.S. in accordance with the Determination of Country of Origin for the Purposes of Marking Goods (CUSMA Countries) Regulations” will be subject to the 25 percent tariffs. This means that only goods that would have been eligible for preferential tariff treatment pursuant to the CUSMA are meant to be subject to the countermeasures.
Second phase (currently paused)
The second phase of the Canadian countermeasures includes the imposition of 25 percent tariffs on other imported U.S. goods worth $125 billion. Although the second list of proposed targeted goods was published on March 4, the implementation of the second phase is now on pause as the U.S. decided to waive the tariffs on products of Canada that are originating under the CUSMA as per the March 6 U.S. Order. The second phase proposes to impose a surtax on several U.S. products such as passenger vehicles and trucks (including electric vehicles), steel and aluminum products, certain fruits and vegetables, aerospace products, beef, pork, dairy, trucks and buses, recreational vehicles, and recreational boats. A 21-day public comment period regarding targeted goods ran from March 4, 2025 to April 2, 2025.
It is also worth noting that Canada implemented other countermeasures as of March 13 using certain goods listed in the list of proposed targeted goods for such second phase as published on March 4 (see below).
Other Canadian countermeasures
As noted above, on March 12, 2025, Canada announced an additional $29.8 billion in countermeasures in response to the section 232 tariffs on Canada’s steel and aluminum products. Such countermeasures, which took effect on March 13, 2025, target U.S. steel and aluminum products as well as other U.S. goods including computers, servers, display monitors, sports equipment and cast iron products. These goods are among those targeted as part of the second phase of Canada’s tariffs implementation, which was paused in recognition of the March 6 U.S. Order, as mentioned above.
All other U.S. measures to be imposed against Canadian goods could be subject to immediate retaliation from Canada, such as reciprocal Canadian tariffs, equivalent tariff countermeasures on other U.S. products, or the implementation of non-tariff barriers, as the case may be.
At the provincial level, various measures have been discussed or implemented. To date, one significant provincial measure that has been announced is a proposed 25 percent export charge on Ontario electricity exports to the U.S., which would affect customers in New York, Michigan and Minnesota. This export charge was to take effect on March 11, 2025, but after the discussions with the U.S. Secretary of Commerce referred to above, it was suspended by Premier Ford.
Finally, in response to the U.S. tariffs imposed on Canadian automobiles and automobile parts in the April 2 U.S. Order, Canada also implemented additional countermeasures, including the application of a 25 percent surtax on (i) non-CUSMA compliant fully assembled vehicles imported into Canada from the United States; and (ii) on non-Canadian and non-Mexican content of CUSMA compliant fully assembled vehicles imported into Canada from the United States.
Canada’s response to the June 3 U.S. Proclamation
Pursuant to the Order Imposing a Surtax on the Importation of Certain Steel Goods (PC Number: 2025-0534) and the Order Amending the Order Imposing a Surtax on the Importation of Certain Steel Goods (PC Number: 2025-0593), , the Government of Canada has implemented TRQs on imports into Canada of steel mill products. Specifically, as of June 27, 2025, imports above the specified volumes for each class of steel goods are subject to a surtax in the amount of 50% of the value for duty of such goods. .
Originally, TRQs applied only in respect of imports into Canada of steel mill products from non-free trade agreement partners (the “Non-FTA TRQs”). However, effective as of August 1, 2025, the TRQs have been extended to countries that have a free trade agreement in force with Canada (excluding Mexico and the United States) (the “FTA TRQs”). The Non-FTA TRQs available are equivalent to fifty (50) percent of 2024 levels, whereas the FTA TRQs available are equivalent to 100 percent of the 2024 levels..
Mitigating Canada’s countermeasures
Remission process
As it is also the case for the current Canadian tariffs imposed on certain goods from China, a general process for requesting the remission of tariffs on U.S. imported goods has been implemented by the Department of Finance (the “General Process”) to mitigate the impact of such duties on Canadian workers and businesses.
The general process for requesting remission of tariffs is available for all goods subject to the surtax .
The duty relief could either be obtained prospectively or retrospectively, as the case may be. In the latter case, a refund of tariffs already paid would be obtained. According to the Department of Finance, the remission could be granted in the following instances:
- To address situations where goods used as inputs cannot be sourced domestically, either on a national or regional basis, or reasonably from non-U.S. sources.
- To address, on a case-by-case basis, other exceptional circumstances that could have severe adverse impacts on the Canadian economy.
Specific remission orders were also enacted in respect of (i) motor vehicles; and (ii) goods that are used in Canadian manufacturing, processing and food and beverage packaging, and for those used to support public health, health care, public safety, and national security objectives.
Specifically, the United States Surtax Remission Order (Motor Vehicles 2025) (the “Motor Vehicle Remission Order”) applies to prescribed motor vehicles that were imported into Canada on or after April 9, 2025, and not later than on April 8, 2026, and is intended to minimize the negative effects of the surtaxes on Canadian motor vehicle companies by providing relief in exceptional situations.
Furthermore, the United States Surtax Remission Order (2025) (the “Sectors Specific Remission Order”) applies to goods that are used in Canadian manufacturing, processing and food and beverage packaging, and for those used to support public health, health care, public safety, and national security objectives. The Sectors Specific Remission Order is intended to minimize the negative effects of the surtaxes on Canadian companies in the above sectors. To qualify for the relief: (i) the good must have been imported into Canada before October 16, 2025; (ii) no other claim for relief of the surtax must have been granted under the Customs Tariff in respect of the good; and (iii) the importer makes a claim for remission to the Minister of Public Safety and Emergency Preparedness (i.e., the CBSA) within two years after the date of importation.
It should be noted that the process in respect of the Motor Vehicle Remission Order and the Sectors Specific Remission Order is much more streamlined than the General Process. For example, to obtain relief of the applicable surtax at time of import, a relevant special authorization code must simply be entered in the Special Authority OIC field on the Commercial Accounting Declaration (the “CAD”). Further, if the imported goods in question qualify for the remission under the Motor Vehicles Remission Order or the Sectors Specific Remission Order, but such remission was not claimed on the CAD, a correction or adjustment may be submitted via the CARM Client Portal or via EDI/API by entering the relevant special authority code in the Special Authority OIC field.
Other forms of relief
Tariffs (with the exception of steel products) are automatically waived where goods are used for specified non-commercial or commercial uses (e.g., as inputs to automobile or aircraft manufacturing), as provided in Chapter 98 and Chapter 99 of the Customs Tariff.
Where conditions are met, importers could also apply for the CBSA Duties Relief Program or Duty Drawback Program to import commercial goods without paying tariffs, or to receive a refund for tariffs paid where goods are eventually exported.
Impact of the Trade War
While it is to be hoped that all issues underlying the imposition of tariffs by both countries will soon be resolved, it is inevitable that the current trade war increases the time and expense of many types of business transactions involving U.S. and Canadian buyers and sellers.
Transaction delays
The implementation of tariffs may reduce the volume of imports and exports and business transactions between Canada and the U.S. If a cycle of tariffs and countermeasures (or reciprocal threats) begins, the resulting uncertainty may, in and of itself, deter businesses from pursuing transactions or at least delay transactions while trade implications are considered, and tariff-specific closing contractual conditions are negotiated.
Transfer pricing impacts
The new tariffs could also have an impact on transfer pricing for multinational groups. Related parties within a multinational group must set their transfer price by reference to similar transactions between unrelated parties. The transfer price, which includes the cost of tariffs to reflect market conditions, determines the allocation of taxable income between related parties. The burden of tariffs generally falls on the importer, whose income would consequently be reduced, unless the parties agree to allocate the cost differently. Take, for example, a transaction between related U.S. and Canadian entities in which the U.S. entity acquires goods subject to tariffs from the Canadian entity: while the U.S. entity (as the importer responsible to pay the tariffs) might argue that such extra costs should be shared between the parties, it is uncertain whether Canadian tax authorities would agree to shift the cost of such tariffs to Canadian entities through a transfer pricing adjustment.
The America First Trade Policy and Report
Broadly, the Policy directs certain U.S. government agencies to investigate the causes of the U.S.’s “large and persistent annual trade deficits in goods, as well as the economic and national security implications and risks resulting from such deficits.” Following this investigation, on April 1, 2025, the U.S. agencies submitted their reports recommending appropriate measures to address the above (collectively, the “Report”).
Among other things, the Report includes:
- A review of certain trade agreements and suggestions on how to modernize same, including by: (i) lowering foreign tariff rates for American exporters, (ii) improving transparency and predictability in foreign regulatory regimes, (iii) improving market access for U.S. agricultural products, (iv) strengthening rules of origin, and (v) improving the alignment of U.S. trading partners in respect of economic security and non-market policies and practices;
- The requirement that the Secretary of the Treasury carry out an in-depth assessment of the policies and practices of major trading partners with respect to currency exchange rates and address the lack of transparency by foreign governments in currency markets;
- A review of the policies and regulations regarding the application of antidumping and countervailing duty laws (“AD/CVD Laws”) and corresponding recommendations including: (i) potentially adding new countries to the list of non-market economies; (ii) methodologies to better implement AD/CVD Laws, and (iii) more-active self-initiation of new investigations.; and
- A quantification of the loss of tariff revenues and an assessment of the import risks resulting from the $800 or less duty-free de minimis exemption, as well as the corresponding recommendation to end same.
The Report also suggests the creation of a new “External Revenue Service” to collect tariffs, duties, and other foreign trade-related revenue.
Future of the CUSMA
