Canada’s ambassador warns Trump tariffs are driving up costs, threatening U.S. investment
Canada’s ambassador to the United States, Mark Wiseman, said President Donald Trump’s tariffs and shifting trade rules are raising the cost of investment and discouraging companies from expanding. His warning comes amid renewed negotiations between Washington and Ottawa and evidence that tariffs are adding to costs for US businesses and consumers.
The US and Canada exchanged about $570 billion in goods in the first nine months of 2026, less than in the same periods of the previous three years. US customs duties on Canadian imports rose to $10 billion in 2025, from $400 million in 2024; New York Fed research found importers bore nearly 90% of tariff costs, with some feeding through to consumer prices. Talks have restarted after collapsing in August, focusing on tariffs on Canadian steel and cars, while Wiseman called for certain duties to be removed.
In short
- Canada’s ambassador says tariffs are raising investment costs.
- US duties on Canadian imports reached $10 billion in 2025.
- Negotiations have resumed, with steel and cars in focus.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Supporters of the tariffs could argue that duties give Washington leverage in negotiations and encourage companies to produce more in the United States, potentially strengthening domestic industries and supply chains. They may see the short-term costs as a worthwhile trade-off if clearer terms or concessions from Canada ultimately improve US economic security and bargaining power.
The case against
Critics could argue that higher duties and shifting rules make cross-border investment less predictable, raising costs for US firms and consumers while weakening trade with a close partner. If importers absorb most of the duties and pass some costs on, the tariffs may undermine the investment and affordability they are intended to support.
