As Canadians, the best thing we can do is to boycott ALL American products (as individual Canadians, not as a government), and to not travel to/thru the US until they exterminate their pathetic fascist infection.
We are nothing more than consumers in this late-stage capitalism scenario, and our money is where we hold ALL our power (and it's a lot of power). Boycotts are actually so effective that both Australia and Israel wanted to make them (and promoting them) illegal.
We don't even need the government to do this. Carney is doing the right thing by playing it cool and we have to do the heavy lifting.
We just need to stop spending our money on American products, tout suite.
