Irish Canadian

Irish Canadians (Irish: Gael-Cheanadaigh) are Canadian citizens who have full or partial Irish heritage including descendants who trace their ancestry to immigrants who originated in Ireland. 1.2 million Irish immigrants arrived from 1825 to 1970, and at least half of those in the period from 1831–1850. By 1867, they were the second largest ethnic group (after the French), and comprised 24% of Canada's population. The 1931 national census counted 1,230,000 Canadians of Irish descent, half of whom lived in Ontario. About one-third were Catholic in 1931 and two-thirds Protestant.

The Irish immigrants were overwhelmingly Protestant before the famine years of the late 1840s, when the Catholics started to come. Even larger numbers of Catholics headed to the United States; others went to England and Australia.

The 2006 census by Statistics Canada, Canada's Official Statistical office, revealed that the Irish were the 4th largest ethnic group, with 4,354,000 Canadians with full or partial Irish descent or 14% of the country's total population. This was a large and significant increase of 531,495 since the 2001 census, which counted 3,823,000 respondents quoting Irish ethnicity. According to the National Household Survey 2011, the population of Irish ancestry has increased since 2006 to 4,544,870.
