John Graves Simcoe was a General of the British Army who later served as the first Lieutenant Governor of Upper Canada, which later became Ontario. He helped in the establishment of institutions such as courts of law, freehold land tenure, trial by jury, and English common law. He also contributed to the abolition of slavery in Canada. Born in Cotterstock, Oundle, England, he joined the British Army at the age of 18. He took part in the American Revolutionary War during the Siege of Boston as a young man. Shortly after that, he was promoted to the rank of Captain. A year later, he is believed to have commanded a massacre of Americans in their sleep. He entered politics as a Member of Parliament from St Mawes, Cornwall. After the Constitutional Act was passed in 1791, giving a representative government to Canada, Simcoe was appointed Upper Canada’s first lieutenant governor. In this post, he promoted immigration, agriculture, as well as road building. Later, he was also made Commander-in-Chief in India. However, he passed away before he could take up this post.
