Do we really need a municipal politics thread to talk about federal policy?
I believe the argument is that we've easily been able to handle our current immigration rate in the past, there's little reason to believe we can't nowadays.
(I couldn't find a graph including 2022-2023, but I believe the immigration rate was about 3% for both if we include both permanent and temporary residents)
I've always maintained that Canada is one of the largest countries in the world with close to unlimited land, and construction labour should be proportional to population, so if we can't provide housing to everyone that arrives in Canada that's a failure in construction policy, not in immigration policy.
