It was just a few years ago that Toronto had the most Italians living outside of Italy..huge huge population here.
Little Italy is a fab spot in town as well as the Italian festivals that are held in several communities.
As of 2006, 1,449,695 Canadians residents stated they had Italian ancestry, in which 741,045 had sole Italian origins while the other 704,285 were of partial Italian origin along with other ethnic origins, chiefly with other European ethnic groups e.g. Italian-Irish, Italian-English, Italian-French, etc. The latter group climbed by almost 25%, while the Italian Canadian population as a whole grew by 12% since the 2001 census.
In 2006 Canadians of Italian ancestry make up 4.6% of the population of Canada, a rise from 4.3% in 2001. The majority live in Ontario (867,980) where they constitute more than seven per cent of the population, while another 300,000 live in Quebec.
