On Wednesday, April 2, 2025, President Donald Trump stood in the White House Rose Garden holding a large cardboard chart and announced what he called "Liberation Day." His executive order imposed a 10% baseline reciprocal tariff on imports from nearly every US trading partner, plus substantially higher rates on roughly 60 countries that the administration deemed "worst offenders." China drew a 34% reciprocal tariff, stacked on top of the existing 20% fentanyl tariff. Vietnam was hit with 46%. The European Union was tagged at 20%.
Canada and Mexico were conspicuously absent from the reciprocal tariff list. That was not a gift. Canada and Mexico remained subject to the separate 25% IEEPA tariff regime that took effect March 4, 2025, which itself had been partially exempted for CUSMA-compliant goods on March 6. The result is a three-way tariff structure that has Canadian freight moving under one set of rules, Mexican freight under another, and the rest of the world under a third. The White House's April 2 executive order text lays out the details, and USTR's accompanying fact sheet clarifies the exemptions.
One week into Liberation Day, the cross-border freight market is in full recalibration. Auto parts lanes are seeing cancellations. Lumber and steel are being pulled forward where possible. Some Canadian shippers that had quietly shifted sourcing to Vietnam or China after the March 4 tariffs took effect are now caught with inventory stranded at US ports facing much higher reciprocal rates. This article walks through what happened, what it means for Canadian freight, and where the cross-border market is headed through Q2 and Q3 2025.
What Happened on April 2, 2025
Trump signed Executive Order 14257 at approximately 4 PM Eastern on April 2, invoking IEEPA authority and declaring a national economic emergency based on "large and persistent annual trade deficits." The order set a 10% baseline tariff effective April 5 on virtually all imports, plus country-specific higher rates effective April 9 for 60 named countries. The country-specific rates were calculated using a formula based on the US bilateral trade deficit with each country divided by total imports from that country, then halved.
Global financial markets reacted with a historic selloff. The S&P 500 dropped 10.5% over April 3 and 4. The Dow Jones lost more than 4,000 points in two sessions. Reuters reported that approximately $5 trillion in US market capitalization was wiped out in the two trading days after Liberation Day. Trade-exposed sectors like transportation, auto parts, and industrial manufacturing led the declines.
Canada's Peculiar Exemption-But-Not-Really Status
Canada and Mexico are not on the reciprocal tariff schedule, which sounds like good news. The reality is more complicated. Canadian goods remain subject to the March 4 IEEPA tariff regime, which imposed a 25% tariff on all Canadian imports (10% on energy) tied to fentanyl and border security. On March 6, the administration issued a partial exemption for goods that qualify for preferential treatment under CUSMA, reducing the effective rate on CUSMA-compliant goods to zero.
In practice, that means Canadian freight moving under CUSMA preference is currently tariff-free at the border. But freight that does not qualify for CUSMA, whether because it includes non-originating inputs that fail the rule-of-origin test or because the exporter did not bother to file a CUSMA certification, faces the full 25% IEEPA tariff. US Customs and Border Protection's guidance on the March 4 tariffs specifies how the CUSMA exemption is applied at the border.
For Canadian manufacturers and exporters, the practical effect is that CUSMA compliance has become essential for every single shipment. Companies that historically ignored CUSMA certification because the tariff was zero under MFN rates anyway are now scrambling to file certifications retroactively and to confirm that their production processes actually qualify. Canadian customs brokers report a 400% increase in CUSMA certification work compared to February 2025.
Sectoral Tariffs Still Hitting Canada Hard
The CUSMA exemption on IEEPA tariffs does not cover sectoral tariffs. Three specific sectoral tariff programs continue to hit Canadian freight:
- Section 232 steel and aluminum tariffs: Reinstated at 25% effective March 12, 2025 on all steel and aluminum imports, including Canadian. No CUSMA exemption. This directly hits Hamilton-area steel producers, ArcelorMittal Dofasco, and Canadian aluminum producers like Rio Tinto's Kitimat and Alma operations.
- Section 232 auto tariffs: 25% tariff on imported finished vehicles effective April 3, 2025, with parts tariffs delayed but coming. Canadian-assembled vehicles from Ontario plants are directly hit unless a USMCA content certification reduces the duty basis.
- Softwood lumber duties: Pre-existing countervailing and antidumping duties on Canadian softwood lumber, currently near 15%, are on a path to approximately 34% following the 2024 administrative review cycle.
"The CUSMA exemption is not a clean win. Steel, aluminum, autos, and lumber remain under separate sectoral tariff regimes that CUSMA does not cover. For Canadian freight in those sectors, the tariff pain is very real and very current."
The Auto Industry Crisis
The Canadian auto sector is in active crisis. Stellantis announced on April 3 that it was idling its Windsor assembly plant for two weeks, pausing production of Chrysler Pacifica minivans and Dodge Charger Daytona EVs, to evaluate the tariff impact. General Motors announced similar reviews at its Oshawa and Ingersoll plants. Honda's Alliston plant and Toyota's Cambridge plant are operating on reduced shifts pending tariff clarity. CBC's April 3 reporting on the Stellantis Windsor shutdown documented the immediate job impact on approximately 4,500 auto workers.
The freight implications are significant and specific. Auto carriers that had been running Detroit-Windsor and Detroit-Toronto lanes at near-capacity for the past decade are seeing volumes drop 20 to 30% in the first week of April. Parts suppliers in Southwestern Ontario, including Magna International, Linamar, and Martinrea, are pausing shipments pending customer instructions on whether and how to absorb the tariff cost.
For carriers running auto parts lanes, the next 60 days will be volatile. Expect volume cancellations on existing contracts, sudden demands for spot capacity as manufacturers try to pre-position inventory, and significant rate volatility as auto lanes rebalance. Carriers with flexibility to reposition capacity from auto-heavy lanes into consumer goods and general freight will be better positioned than those with concentrated auto exposure.
The Cross-Border Freight Market Response
Volume Patterns
Southbound cross-border volume from Canada to the US dropped 12% in the week after Liberation Day compared to the March weekly average, per preliminary DAT freight index data. Northbound volume dropped roughly 5%. The asymmetry reflects the fact that Canadian exporters are the ones absorbing the sectoral tariffs, while US exporters to Canada have continued operating under more stable conditions (with the exception of Canadian retaliatory tariffs that took effect March 4).
Rate Movements
Spot rates on Ontario-to-US Midwest lanes dropped 3 to 5% in the first week of April as auto-related volume softened. Spot rates on BC-to-Washington and BC-to-California lanes held firm, supported by consumer goods volume that was not materially affected by the auto-specific tariffs. The DAT van linehaul rate index posted its first week-over-week decline in six weeks during the week of April 7.
Border Wait Times
Curiously, border wait times have declined. The reduced commercial volume, combined with CBP's scaling up of inspection capacity in anticipation of the tariffs, has reduced average wait times at major crossings by 15 to 25%. Ambassador Bridge, Peace Bridge, and Pacific Highway are all reporting faster average clearances in the first week of April than in February or March.
Specific Lane Impacts
Ontario-to-Midwest (Auto Corridor)
The Windsor-Detroit-Chicago corridor is the single most affected lane. Expect 20 to 30% volume reduction through April and early May as auto plants idle and parts suppliers reduce inventory. Carriers running this lane should prepare for spot capacity opportunities as manufacturers try to pre-position inventory, but overall volume will be down.
Ontario-to-Northeast (Consumer Goods)
The Toronto-to-NYC and Toronto-to-Boston corridors are mixed. Consumer goods volume remains relatively stable because these are mostly CUSMA-compliant. Industrial and specialty goods (steel, machinery) are down because of the sectoral tariffs. Net effect: roughly flat week-over-week.
BC-to-Washington and BC-to-California
The Pacific corridor has seen the least disruption. BC exports to the US West Coast are heavily weighted toward forest products (subject to existing softwood duties but not to new Liberation Day tariffs), seafood (CUSMA-compliant), and consumer goods (CUSMA-compliant). This lane is close to holding stable.
Prairie-to-US Corridors
Alberta and Saskatchewan exports are heavily weighted toward energy and agricultural commodities. Energy shipments are protected by the 10% energy-specific IEEPA rate. Agricultural exports (canola, pulses, wheat) are mostly CUSMA-compliant. Prairie lanes are the most stable of the major Canadian export corridors.
What Comes Next
The next 90 days will be defined by three things: whether Trump rolls back any portion of the tariffs in response to market pressure, whether affected industries successfully lobby for additional exemptions, and how Canadian and other affected countries retaliate. The April 9 country-specific rates are the moment of maximum pressure. If the market panic continues, a rollback becomes more likely. If financial markets stabilize, the tariffs may stick.
For Canadian shippers, the near-term focus should be on:
- CUSMA certification compliance: Every single cross-border shipment should have rock-solid CUSMA paperwork. This is the single highest-leverage thing Canadian exporters can do right now.
- Sectoral tariff exposure mapping: Identify which of your products fall under Section 232 or other sectoral tariff programs and model the margin impact. Product lines that are unprofitable at the current tariff rate need pricing decisions made proactively.
- Carrier diversification on affected lanes: Carriers who had been concentrated on auto lanes are going to be stretched thin. Building relationships with carriers outside the auto corridor buys you flexibility when the auto carriers start chasing volume.
- Forward-buy on tariff-exempt inputs: Where your inputs are currently CUSMA-exempt or otherwise protected, there is value in pre-buying at current rates. The regulatory environment could tighten further.
The Pacific corridor has been the most stable cross-border market through Liberation Day. Keylink Transport runs BC-Washington, BC-Oregon, and BC-California lanes daily, with CUSMA-compliant documentation built into every shipment. Talk to our dispatch team about Q2 capacity.
Reserve Capacity →The Bottom Line
Liberation Day was bigger in rhetoric than it was in immediate impact on Canadian freight, but the indirect effects are significant. Canadian goods mostly escape the reciprocal tariffs if they are CUSMA-compliant, but the sectoral tariffs on steel, aluminum, autos, and lumber continue to hit hard. The global market turmoil from the reciprocal tariff announcement has also reshaped broader freight dynamics, with auto lanes dropping and general consumer goods lanes relatively stable.
The Canadian carriers and shippers who handle Q2 2025 best will be the ones who lean into CUSMA compliance, diversify their lane exposure away from tariff-heavy sectors, and communicate proactively with their customers about what is actually changing and what is holding steady. The ones who are paralyzed by the uncertainty and wait for the dust to settle will find themselves with empty lanes and no commercial relationships when the dust clears.
