This paper analyzes the changing characteristics of Chinese immigrants to Canada between 1980 and 2001. It reveals that recent Chinese immigrants to Canada constitute a substantially different group from those of former years. They are no longer a homogeneous group from the rural areas of Guangdong Province of Mainland China, but in fact citizens of 132 countries, speaking 100 different languages and dialects. This study also reveals significant differences among Chinese subgroups. Immigrants from Hong Kong and Taiwan shared more commonalities than with those from Mainland China. Given Canada's time dependent immigration selection procedures, these differences are rationalized on the basis of a proposed single and double selection theory.
