From The Chinese in Toronto from 1878: From Outside to Inside the Circle | Arlene Chan | 2011 (available in a public library)
Surname and home territory were used as eligibility for membership in the clan and distriction assocaitons. The early immigrants, who came to Canada in the 1880s, were predominantly (87 percent) from Si Yi, meaning Four Counties or Districts, and San Yi, meaning Three Counties or Districts, all southwest of the capital city of Guangzhou in the Guangdong province ....
The four counties in Si Yi are Taishan, Kaiping, Xinhua and Enping, the homebase of 64 percent of the immigrants. Nearly one quarter of all Chinese immigrants came from the Taishan county alone, a mountainous coastal region where the agricultural output could only support its population of half a millsion people for four months out of the year .... [p. 52]
In 1910 there were 10 clan and two district associations in Toronto (see Table 8). The most prominent famly associaton halls were located around Dundas Street and Elizabeth Street, the centre of the Chinese community. [p. 54].
