John A. lived in a very different time than we currently do. Did settler of Canada while it was becoming a nation come here to get free housing, free healthcare, a robust welfare program, and then bring their parents over who never contributed to Canadian Pension Plan but collect it?

No they showed up and turned a country of wilderness into farmland, and if they didn't work they starved to death.

We can admit things have changed in the last 150 years, and it's no longer reasonable for an immigrant to be a Canadian politician. In the globalized society we currently live in, these people don't have the best interests of Canadians at heart, they're all beholden to the special interests of their hyphenated Canadians and the countries of their birth.
