That's a tough call. While EV's don't generally need much of any service, when they do, you really want someone who is trained on them to do it right. Throw in the (maybe) colder climate, and your winter driving range may be a factor for much longer than where you are now. If everything you normally do is in the city, that may not be a factor at all. Then, a software or recall or service campaign update, and it may be both time consuming and inconvenient. No idea what the electric costs or fuel costs are, but maybe high, that may make a difference. There are some subtle differences in standard equipment between the USA and Canada, but I do not think that would be an issue. For example, I don't think they use the TPMS, and rely on the less exact rolling diameter detection to find a low tire. So, if something went on that, they may neither have the training or the parts. Canada requires daytime running lights, so the menu choices on theirs may be different, but as long as you left it on, you'd not have an issue. There may be other subtle differences.
