Canada's Exports to US Surge Ahead of New Tariffs
Confirmed
In Short: Descartes Systems Group noted that the figures also reflect “accelerated shipments in response to shifting trade policies,” including “suspected aggressive frontloading” of imports ahead of anticipated tariffs.

Canadian exports to the US surged in August, driven by companies frontloading shipments in anticipation of new tariffs announced by President Donald Trump.
According to Statistics Canada, exports to the US rose 8.1% month-over-month, while imports from the US fell 2.5%, causing the US trade surplus to balloon from C$6.1 billion to C$11.2 billion—the largest monthly increase since records began.
The August trade balance posted a surplus of C$4.2 billion, expanding far more than expected from July's C$790 million surplus.
The surge in exports to the US was heavily influenced by tariff-related developments, with the US share of total exports rising to 69.8% from 66.1% in July.
Descartes Systems Group noted that the figures also reflect “accelerated shipments in response to shifting trade policies,” including “suspected aggressive frontloading” of imports ahead of anticipated tariffs.
The peak shipping season is fully in motion, according to Judah Levine, head of research at Freightos, as container rates benefit from a wave of frontloading driven by additional tariffs and escalating Middle East tensions that raise fuel expenses.
The US Trade Representative announced new tariffs on 60 countries it determined have not sufficiently addressed imports produced by forced labor, potentially increasing the cost of goods once again.
The anticipation of steep tariff increases has propelled imports to the US during the first seven months of this year, but ongoing uncertainty and volatility mean wholesale changes to supply chains are not yet materialising.
Despite ongoing economic headwinds, consumers are continuing to spend, but affordability is a key factor affecting their spending habits.
The Supreme Court’s February ruling struck down tariffs imposed under the International Emergency Economic Powers Act, potentially triggering refunds exceeding $90 billion.
However, the new tariffs target only about 5% of Canada's exports to the US (worth approximately C$28 billion), and according to estimates by RBC, more than 80% of Canadian products are still exported duty-free under the United States-Mexico-Canada Agreement (USMCA).
What this adds
The surge in exports ahead of new tariffs has created a significant trade surplus for Canada, but ongoing uncertainty around tariff rates, duration, and exemptions makes long-term planning challenging for businesses.
The frontloading of shipments has also affected trade patterns, with exports to countries other than the US falling 8.5% from the record high set in July, and the trade deficit with non-US partners widening to C$7.0 billion.
What's confirmed
- US companies have been braced for heavy duties on goods imported from major trading partners, including Canada, China, the European Union and Mexico, since President Donald Trump’s inauguration in January.
- In practice, the introduction of tariffs has been unpredictable, characterised by last-minute adjustments and delays.
- Though seasonal demand tends to be strong in July, Descartes says the figures also reflect “accelerated shipments in response to shifting trade policies”, including “suspected aggressive frontloading” of imports ahead of anticipated tariffs.
What's still developing
- Consumers in August projected higher future gasoline prices.
- Carney made the remarks in a video released just hours after his government made good on a promise to implement retaliatory tariffs on the United States.
- In January 2025, before being sworn in for his second term, Trump ruled out using military force but said he would consider using “economic force” to make Canada part of the U.S. Canada’s reciprocal tariffs took effect Tuesday in response to Trump’s latest round of 50 per cent tariffs targeting dozens of products, including honey, hockey sticks, milk and cheese.
- Levine noted that the trans-Pacific ocean peak season is well underway, with some observers citing frontloading ahead of an approaching tariff deadline as a factor behind the early start.
- Separate Section 301 investigations could result in new tariffs on Brazil and 16 other trading partners, moves that Deborah Elms, head of trade policy at the Hinrich Foundation in Singapore, called astonishing.
- Contracted shippers may be advancing shipments ahead of an 80% increase in fuel surcharges starting in July, when the quarterly Bunker Adjustment Factor is updated.
- Trump announced this week that a 30% tariff on imports from China would be delayed for an additional 90 days, meaning duties now stand at 20% with additional rates for specific sectors such as aluminium and steel.
- Both gateways are comparing against January 2025, when importers frontloaded cargo ahead of anticipated tariff increases.
- “We’re comparing to elevated cargo levels from last January when importers were scrambling to get cargo in ahead of tariffs,” said Gene Seroka, Executive Director of the Port of Los Angeles.
- The port handled 9.9 million TEUs in 2025, when “uncertainty prompted shippers to move goods before tariffs and reciprocal tariffs were implemented last spring,” according to Port CEO Dr. Noel Hacegaba.
- “We are leading the nation in trade, and providing a safe harbor in the sea of tariff and trade uncertainty for our customers and the goods movement industry,” Hacegaba said during a Supply Chain Insight virtual media briefing.
- “While this decision ruled on the legality of the IEEPA tariffs, it did little to remove the uncertainty we’ve seen – and continue to see – across the global supply chain,” Hacegaba said.
