Loyalist Landing at Cataracoui 1784
Following the end of the American Revolution in 1783, Frederick Haldimand, Governor of Quebec, approved the resettlement of loyalist refugees in what is now southern Ontario. Favourable reports on the Cataracoui area led to its occupation by British forces in the spring of 1783 and to the commencement of surveys the following October. In June 1784 a party of Associated Loyalists from New York State under the command of Captain Michael Grass, part of a loyalist flotilla travelling from Montreal, established a camp here on Mississauga Point. Grass later recalled: "I led the loyal band, I pointed out to them the site of their future metropolis and gained for persecuted principles a sanctuary, for myself and followers a home".
