I'm not gonna blame anyone for fleeing fascism. At least if you leave, they're not getting your tax dollars* or labour.
That said, be aware that there is a housing crisis in Canada, and it's most severe in the metro Vancouver area.
*I think you would actually have to renounce US citizenship for this to be true, but I'm also unsure how aggressively the IRS would pursue tax collection from emigrants.
To be clear, that wasn't meant as a discouragement, more just as a heads-up on what to expect.
It's "better" in smaller towns, but that comes at the cost of less infrastructure and services.
Imo it's been pretty predictable for years that we might need to absorb a lot of US emigrants, and while it's very popular to blame the housing crisis on new arrivals, it's fundamentally the result of decades of policy failures by successive governments of a country that relies heavily on immigration.
That said, there are probably better options for those who can afford it.
