Between 1837 and 1841 several acts were passed by the Legislature of Upper Canada which set apart Simcoe District. These acts named the townships that the County would encompass and authorized the levying of taxes for the purpose of constructing a jail and court house. On January 11, 1843, the jail and court house having been duly erected, the Governor General proclaimed the County of Simcoe to be a separate and distinct District. The province of Canada also appointed James R. Gowan as the first judge of the District of Simcoe.
