It could be that the Poilievre Cons defeat Trudeau in the next election but as you said there is a limit to what the government can do. Poilievre says that everything is broken yet has no solutions and only blames bumbling Trudeau for this mess.Honestly, it wouldn't look like much because I don't trust the government. You have to make your own luck. Anyone that sits on their hands waiting for some government policy to benefit them is a loser. They can vote for an official and hope they deliver but to expect it is stupid.
Mass immigration to Canada necessarily would still happen despite who wins the next election anyway so that the FOB influx will continue. A record amount of newcomers, upwards of two million more will come into Canada primarily from India in the next 24 moths.
