This comment suggests that these people are being "tricked" into believing something they don't. Canada is not "falling" any more than it ever has, because it has always existed to do what these movements intend to do, which is to extract and generate profit. None of this would be effective if there was actually a popular opposition to liberalism and fascism in Canada, but the culture is already conducive to those ideologies because it is a settler-colonial state built according to their imperatives. If the trick is meant to be that these people are voting against their best interests, then like, what are the Oil Sands then? Some genuine benefit? What about all the other ways in which Canada reproduces and violently defends a system that works to the detriment of all but the wealthiest and most privileged in society? Carney is a neoliberal and has unsurprisingly used the advantage of this moment to expand state investment in private capital, is he a Russian plant?
Many settlers choose fascism because they would rather secure privilege in a failing system than risk their security by committing to meaningful and substantial change. The reality is that these movements are an inevitable consequence of capitalist systems as their extractive pursuit of profit begins to disrupt the hierarchy within the metropole. Middle class Canadians are hurting more than any of us can remember, as short as that memory may be, and they have readily embraced racist, ableist, and classist policies that target vulnerable groups as solutions to problems inherent to capitalism, like housing and employment insecurity. Canada is not being "corrupted" by foreign actors, these groups are capitalizing on preexisting conditions in Canada, and because Canada has always been like this, those empowered by this hegemony readily comply and profit themselves.
