It's such a wildly inconceivable idea that the U.S. would invade and conquer Canada, but just for arguments sake, if it did happen, I doubt Canada would resist like Ukraine against Russia. I'm not saying people would be fine with it, but I also don't see Canadians making those kinds of sacrifices.

I could see the U.S. taking islands in the Arctic archipelago because they pretty much can, but I doubt even that would lead to an all out war. In fact, I would bet on it that they will start claiming islands up there.

I think the take over of Canada would be a slow burn, an erosion of sovereignty. They have already shown that they can use economic threats to make our government act how they want it to, and that will just continue. Eventually they will be dictating policies at higher and higher levels, followed by more "joint institutions", giving American agencies power on Canadian soil, followed by military integration, and economic union. The border won't be erased overnight, but over time.
