The Upper Canada Act against Slavery was passed on July 9th, 1793 and it considerably impeded the future development of slavery in Canada. In his address to the assembly, Simcoe praised the act by noting that it was a:
"Singular pleasure that such persons as may be in that unhappy condition which sound policy unites to condem, added to their own protection from all undue severity . . . may henceforth look forward with certainty to the Emancipation of their offspring."
In late 1796, Simcoe left Canada and was appointed Governor of Santo Domingo (Haiti). Illness forced him to return to Britain for a period of time. Later in life, in 1806, he was appointed Commander-in-Chief of India, but died before he could leave the country. John Graves Simcoe died on Oct 25th, 1806, at Topham in Devonshire, England.
