Peel County is a historic county in the Canadian province of Ontario. It was created in 1851 from a portion of York County. In 1973, Peel County became the Regional Municipality of Peel, as a result of the Ontario provincial government's regionalization of the rapidly developing counties surrounding Toronto.
Named for Sir Robert Peel, Prime Minister of the United Kingdom, the county was organized in 1849. Settlers, however, were in Toronto Township as early as 1807. The Credit River was reserved for the Mississaugas, however they sold their land and moved to the Bruce Peninsula.
The community of Malton had its beginnings about 1820. Likely named for Malton, North Yorkshire by local settler Richard Halliday.
Other historical communities in Peel County were: Town of Brampton in Chinguacousy Township, opened in 1834 when John Elliott laid out the lots and named the Place. Incorporated as a village in 1852, and as a town in 1873. Named by settler John Eliot and likely linked to Brampton, Carlisle, Cumbria in England.
Village of Bolton in Albion Township. James Bolton, the first settler, in partnership with his brother George, built a grist mil in 1824.
Village of Port Credit, in Toronto Township, named for French trading post Port-de-crédit.
Village of Streetsville in Toronto Township. John Barnhart opened the first store in 1821 and Timothy Street built a saw and grist mill.
