Europe. Chinese immigration Prior to 1885, restrictions on immigration were imposed mostly in response to large waves of migrants rather than planned policy decisions. Such restrictions, at least as official policy, would not explicitly target any specific group or ethnicity of people until 1885, with the passing of the first Chinese Head Tax legislation by the MacDonald government in response to a growing number of Chinese migrants working on the Canadian Pacific Railway. Subsequent increases in the head tax in 1900 and 1903 limited Chinese entrants to Canada, and it was followed by 1907 major riots against 'Oriental' people (i.e. Asians) in Vancouver, BC by Asiatic Exclusion League. In 1923, the government passed the Chinese Immigration Act which excluded Chinese people from entering Canada altogether between 1923 and 1947. In recognizing Canada's historical discrimination against Chinese immigrants, an official government apology and compensations were announced on 22 June 2006. Fourth wave, 1940s–60s The fourth wave came from Europe following World War II, and peaked at 282,000 in 1957. With many of these migrants coming from Italy and Portugal, Pier 21 in Halifax, Nova Scotia proved to be an influential port for European immigration. From 1928 until ceasing operations in 1971, the Pier would receive 471,940 Italians, becoming the third-largest ethnic group to immigrate to Canada during that time period. Immigrants from Britain, however, were still given the highest priority, and 'Canadianization' would become of great importance for new arrivals who lacked a British cultural background. There would be no such effort to attract Francophone immigrants. In regard to economic opportunity, Canada was most attractive to farmers headed to the Prairies, who typically came from Eastern and Central Europe, as immigrants from Britain preferred urban life. As such, the Church of England took up the role of introducing British values to farmers newly arrived in the Prairie provinces, although, in practice, they clung to their traditional religious affiliations. Nonetheless, around the 1960s, Indo-Canadians would establish themselves in Canada's exurban and rural agriculture and become a dominant feature in British Columbia's farming sector, having already primarily been established in the provincial forestry industry since the turn of the 20th century. Hispanic immigrants would follow similar lines, particularly in regions that were linked with strong farming settlements immediately south of the border. With the economy still expanding, Canadians did not always demonstrate sufficient mobility to fill the hiring needs of some regions, nor
