I think a big takeaway from the US election is that the people really only care about what is in front of them, and right now it’s high prices and unaffordability. In the Canadian case, it would also include healthcare.
But, I would argue that even if Trump threatens to leave NATO and NORAD, Canadian defence and sovereignty wouldn’t be a big vote-changer. It would spark lots of articles and posts, but any of the major parties can probably slow-roll it and be politically fine.
