As in the United States, the Chinese Canadian community traces its roots to early immigrants from Guangdong during the latter half of the 19th century. Later Chinese immigrants came from Hong Kong in two waves, first in the late 1960s to mid 1970s, and again in the 1980s to late 1990s on fears arising from the impending handover to the People's Republic of China. Chinese-speaking immigrants from conflict zones in Southeast Asia, especially Vietnam, arrived as well, beginning in the mid-1970s and were also largely Cantonese-speaking.
