Last Trump admin the US tariffed China, China retaliated by tariffs on US ag goods. Eventually Trump caved (or genius negotiation depending on your political colour) and China lifted the tariffs. Ask American farmers if they got those contracts back once China developed relationships with Brazilian farmers instead. Look at how many small farms folded since then and have been bought by commercial interests. Think that’s a coincidence? Only megacorporations can afford to wait out the consequences of these actions.
The consequences of this idiocy will last a long time.
Trump’s tariffs are universal. Meaning that even in cases where the only practical option is Canada, for example potash, they have to suffer a direct 25% price increase.
The Canadian tariffs are highly selective, we only tariff goods that have alternate non US suppliers at similar prices. In this case the tariffs would mostly reduce market competition without directly affecting price.
I think the better approach is to not enforced the digital lock aspects of the free trade agreement and have Canada be a leading repairer of farm and industrial equipment.
