"don't you think our country should have a 100 million people?"
Why would you think stuffing another 60 Million people into Canada would be a good thing? One of the reasons why Canada is such a nice place to live and why so many people want to come here is that Canada isn't wall to wall people like the countries they are leaving. The world needs fewer people, not more. That isn't xenophobia as you claim it is simply wanting to preserve a good environment, wanting to not increase stress on the environment and wanting to keep Canada's carbon footprint in check.
