The Nintendo Wii SoC was actually fabbed in Canada and exported, but that facility has changed into something slightly different because the whole east coast/hudson river valley fab world went sideways a while ago.

More importantly for Canadians that food or energy has no alternative competing market to sell into. Consequently the Canadians are totally dependent on the US market to even set the price of it. This applies to many other sectors as well.

Canada is currently having a huge desperate push to export to non US markets because of the levels of uncertainty that have been created. And I say this as someone not totally dismissive of the US position, but they need to do a far better job of bringing their allies into the tent with them.
