Idk. Like 95% of the services Canadians use are supported/enabled by the USA. Services trade, for some reason, isn't discussed/included in most of the bluster around the trade deficit etc -- if it was included, things are massively lopsided in favour of the USA.
And if the USA pulls those services, it'd likely be chaos -- Canada would capitulate. Like ask Canadians/Canadian businesses if they're prepared to give up their cell phones, email, windows, streaming media like Netflix, Apple, etc etc. From what I've seen, they'd rather capitulate, than have any decrease in their standard of living.
Even something like the drop in travel. While there are some people I know who are avoiding travel on principle, for a larger number of people it's more just a matter of it costs a lot -- but they have no particular reservations about going to disney or whatever. Even know some who vacationed in floriida recently, drove past mara lago and all that crap.
Tariffs didn't work in the past, but Canada wasn't so much of a bitch in the past. Now, most Canadians are absolutely reliant on the USA, and products/services from the USA, to the point that they likely can't function without that foreign country. Alberta is more inclined to buddy up with Trump/America, in large part because most of Alberta's economic activity is totally reliant on the USA, not on other Canadians. Pretending like we're going to be resilient now, just because in the past we were more independent/able to withstand this sort of pressure, is a bit naive to me.
