After the land was surveyed, much of it was given in the form of land grants to United Empire Loyalists. They emigrated from the Thirteen Colonies during and after the American Revolution, as well as loyalists from New Brunswick. A group of settlers from New York City arrived in the 1830s. In 1820, the government purchased additional land from the Mississaugas. Additional settlements were established, including: Barbertown, Britannia, Burnhamthorpe, Derry West, Elmbank, Malton, Meadowvale Village, Mount Charles, and Streetsville. European-Canadian growth led to the eventual displacement of the Mississaugas. In 1847, the government relocated them to a reserve in the Grand River Valley, near present-day Hagersville.
