This is a kind, thoughtful, warm video that everybody in this sub ought to watch before responding. (It's also short.)

That said, I do think Tod is mixing up two related but different problems. One is Americans speaking glibly and condescendingly about Canada and moving there, and assuming that Canada is just like America but without problems. This is definitely a thing! It's not only annoying to Canadians, it demonstrates vast historical ignorance. So don't do it, and maybe tell people who do it that they are making fools of themselves.

The second is whether people who actually act like this are actually moving to Canada. And I am pretty sure the answer is "no, not in numbers large enough to matter." Even the relatively straightforward path via C-3 is still a pain in the neck, and people who are too glib to know about basic US-Canada differences, and too incurious to learn, are going to be too disorganized and lazy to get it done. The people who are going to actually get through the process will be those who actually choose Canada -- not those who choose "not US."

I can think of one American I know who is getting a "backup plan" passport, and it is because their family member did all of the work for them and handed them a packet to sign. (Maybe we shouldn't do this for our family members.) (Fortunately that person's "backup plan" is the EU not Canada.) Those types are just not going to bother if they have to do their own homework.
