John Graves Simcoe (25 February 1752 – 26 October 1806) was a British Army general and the first lieutenant governor of Upper Canada from 1791 until 1796 in southern Ontario and the watersheds of Georgian Bay and Lake Superior. He founded York (now Toronto) and was instrumental in introducing institutions such as courts of law, trial by jury, English common law, and freehold land tenure, and also in the abolition of slavery in Canada.
