Thank you, Mr. Chair and members of the committee, for the invitation.
In my opening remarks, I'm going to focus on the work that I've spent much of the past two years studying in terms of the economic implications of tariffs between Canada and the United States. I do want to say right up front that, of course, Canada's response involves many considerations: diplomatic, strategic, political and so many others. Economics is just one aspect, and reasonable people can weigh different factors differently. My aim is really just to try to explain some of the economic costs and trade-offs involved.
I'll offer three main observations. First, I think U.S. tariffs may be better understood as American domestic policy rather than as a bilateral dispute with Canada. Second, retaliation by Canada adds to Canadians' costs. Third, the effect of retaliation, particularly on U.S. policy, appears to be quite limited.
I'll start with a shock. First, it's, of course, enormous. I don't need to convince anyone of that. It is perhaps, and at moments last year was, the largest trade policy change in U.S. history—so, in 250-plus years. The average U.S. tariffs rose from about 2% in 2024 to over 30% in April 2025. Those “liberation day” tariffs did not last, but today we are at around an 11% average effective tariff levied by the United States. That's about five times the previous level.
These are broad. They affect nearly every country. I think this is a critically important point. Earlier this year, imports from China, for example, faced average rates near 30%, and Germany and Japan faced around 12% and 15% respectively. This is compared to about 8% for Canada today. The latest data from the U.S. International Trade Commission shows that 93 countries have higher average rates of tariffs applied to them than Canada. This may be less of a trade war with Canada than a fundamental change in how the United States runs its economy.
In theory, a tariff is equivalent to a domestic consumption tax plus a production subsidy of the same rate. I think that way of thinking about it is perhaps a bit more helpful in the current context. Had the U.S. simply adopted a broad-based consumption tax and a set of production subsidies, we would be viewing them very differently, and retaliation might never have come up.
That doesn't mean the costs to Canada's economy are small. They certainly hit some regions more than others. Ontario and Quebec firms, for example, face average rates roughly double the national average. Our economy might be about 2% smaller than it otherwise would have been, based on where we are relative to the Bank of Canada's projection before all of this began early last year. Now, a lot of that cost might be from uncertainty rather than the tariffs themselves, but even the PBO analysis from just a few days ago suggests that the tariffs might be contributing about 1.5% of a reduction to Canada's economy.
Let's turn to retaliation, my second point. These are taxes, and they're paid by Canadians. The round of retaliation that we levied in 2025 raised about $4 billion in federal revenue over the six months that they were in place for.
As for the latest round, beginning last month, I estimate that they may raise consumer prices by something in the order of about one-quarter of a percentage point and cost consumers about $100 million per week that they're in place. The burden is hardest on those least able to afford it. I estimate that households earning less than $30,000 may lose about half a per cent of their disposable income as a result of just the newly enacted retaliatory tariffs. That's triple the hit to those earning above $150,000.
Retaliation also raises business costs, as Dan mentioned. I estimate that machinery and equipment investment costs may be about 0.7% more expensive now as a result of the retaliation that weighs on investment and productivity.
Third—and I'll make this point quickly, as I'm getting to the end of the five minutes here—retaliation's main goal is to change U.S. behaviour. It is really difficult for a small country's tariffs to actually have meaningful economic costs on the target country—in this case, the United States. This is a challenge that all countries of Canada's size face. There are some things where we are large and where the tariff might be felt by domestic producers in the United States, but the opportunity for that is very, very limited.
I think our focus should really be on ensuring that economic strength and resilience are there, despite the challenges we face internationally. I'd be happy to talk about some of the potential options there in the questions.
If we think about what's going on now as just a change in U.S. domestic policy rather than as something uniquely targeted against Canada, then our response can focus more on domestic policy improvements rather than this dispute and fight back and forth with the United States.
Thank you. I look forward to your questions.
