Western Canadian here (BC) -- I agree with Moe on this one.
Tariffs on them imply they're still generally safe to use / drive -- it's not a 'ban' after all, for being unfit for the road or a security risk. Tariffs make sense to some degree if/when there's a local industry you're protecting, especially if/when the good is a luxury.
In the case of EVs though, getting off of gas is a priority in terms of reducing emissions / combating climate change -- it's not so much a luxury even, given how many of our cities are designed for car-oriented travel. I'd rather we had $20k EV options from BYD, rather than we continued to push gas cars and/or EVs that are in the $40-50k from US manufacturers, as it'd mean faster adoption of EVs and faster exit from gas cars. We have literally had multiple cities burn to the ground due to climate change lately. You'd think we'd be above political nonsense on this subject.
