Irish Canadian are immigrants and descendants of immigrants who originated in Ireland. 1.2 million Irish immigrants arrived, 1825 to 1970, 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 Protestants.
The Irish immigrants were largely Protestant before the famine years of the 1840s, when the Catholics arrived in large numbers. However, most Catholic Irish after 1850 usually headed to the U.S., England, Australia and Scotland.
In 1822, the British Government established a trial emigration scheme for Irish paupers to Upper Canada. There were two waves of emigration, one in 1823 the second in 1825. See Geni project Peter Robinson Settlers 1823-1825
