I beg to differ, I think import 5x the amount of population from the same part of the world has a major impact on any country, especially if the government doesn't plan for the sudden increase in population by expanding infrastructure, healthcare, housing etc.

Leaving the social issues aside, this was very poorly planned and average Canadians, especially young ones are feeling the pressure as a direct result of these policies.

Of course there are other factors but to argue that this is "sudden" and misplaced is not genuine.
