Bringing in culturally-incompatible foreigners has certainly been a significant problem in Canada.

Bringing in low-skill, low-productivity, and often criminally-inclined foreigners (especially refugees) has also been a significant and socially-costly problem in Canada.

Bringing in foreign "students" has harmed the quality and reputation of Canada's education systems.

Bringing in adult foreigners to do the low-end, part-time jobs that Canadian high school students and university students used to do has hurt Canada economically, and resulted in atrocious service in many retail stores and restaurants.

Bringing in huge numbers of foreigners each year, while simultaneously restricting the construction of new housing, has created severe pricing distortions in the housing and rental markets. These foreigners also put immense strain on the already-insufficient transportation and health care infrastructure.

What you say about "integration" is a myth. A visit to the cities surrounding Vancouver or Toronto will make that very clear, very quickly.

Immigration has been disastrous for Canada.
