Canada is a nation of 40 million people. We are LEGALLY importing over 1 million people per year. This is when you add up all the legal programs. We are in a housing crisis here, there's not enough homes being built to keep up with the demand. Canada, like the US, has had periods of successful immigration. But recently mass immigration has had a negative effect. Yes, most nations need some form of legal immigration. However, America needs to look at Canada or even the UK where legal mass immigration has expanded over the past decade and its negative consequences.
