Successive federal governments (both Conservative and Liberal) and a Prime Minister disagree with you per his quotes:

"Canada must populate or perish - that is the answer. With such great resources as we possess, and such extensive territory, we can't survive with a small population."

"There cannot be friendship and understanding between the continents if the Western world arrogantly assumes a monopoly of skill and wisdom or that we must try to make all other peoples conform to our way of thinking."

"I have an intensive hatred for discrimination based on colour."

And the PM?

The inspiration for my Conservative political philosophy... Tory PM John Diefenbaker.

It was Dief's government that ended the racism and white preferences in Canada's immigration laws in 1962 and opened up immigration and refugee selection.
