Between 1815 and 1850, some 800,000 immigrants came to the colonies of British North America, mainly from the British Isles, as part of the great migration of Canada. These included Gaelic-speaking Highland Scots displaced by the Highland Clearances to Nova Scotia and Scottish and English settlers to the Canadas, particularly Upper Canada. The Irish Famine of the 1840s significantly increased the pace of Irish Catholic immigration to British North America, with over 35,000 distressed Irish landing in Toronto alone in 1847 and 1848.
