The Chinese Canadian community in the Greater Toronto Area was first established around 1877, with an initial population of two laundry owners. While the Chinese Canadian population was initially small in size, it dramatically grew beginning in the late 1960s due to changes in immigration law and political issues in Hong Kong. Additional immigration from Southeast Asia in the aftermath of the Vietnam War and related conflicts and a late 20th century wave of Hong Kong immigration led to the further development of Chinese ethnic enclaves in the Greater Toronto Area. The Chinese established many large shopping centres in suburban areas catering to their ethnic group. There are 679,725 Chinese in the Greater Toronto Area as of the 2021 census, second only to New York City for largest Chinese community in North America.

Chinese Canadians are Canadians of full or partial Han Chinese ancestry, which includes both naturalized Chinese immigrants and Canadian-born Chinese. They comprise a subgroup of East Asian Canadians which is a further subgroup of Asian Canadians. Demographic research tends to include immigrants from Mainland China, Taiwan, Hong Kong, and Macau, as well as overseas Chinese who have immigrated from Southeast Asia and South America into the broadly defined Chinese Canadian category.
