Today, most immigrants settle in Ontario, British Columbia, Quebec and Alberta and 7 out of 10 live in the 3 largest cities: Toronto, Vancouver, and Montreal. Provinces control some aspects of immigration, attempt to make sure immigrants meet their needs. In Provincial Nomination Program, provinces can "nominate" a percent of the immigrants Canada selects each year. For example, BC can specify that it needs immigrants with particular skills. The program also allows provinces to establish their own immigration offices in different countries. The Provincial Nomination Program increases the likelihood that immigrants will live in the provinces whose labor needs match their skills. Alberta mostly needs construction workers, automotive service technicians, chefs, civil engineers, crane operator, and heavy-duty equipment mechanic.
