Lower Canada Rebellion
When news of the arrest of the Patriote leaders reached Upper Canada, William Lyon Mackenzie launched an armed rebellion in December 1837. In the meantime, filibusters from the United States, the Hunter Patriots, formed a small militia and attacked Windsor, Upper Canada, to support the Canadian Patriots. This resulted in the declaration of martial law by the Lower Canadian government.
Upper Canada Rebellion
When the Lower Canada Rebellion broke out on October 9, 1837, Bond Head sent all the British troops stationed in Toronto to help suppress it. At the beginning of November, a meeting of 15 reformers at John Doel's house rejected Mackenzie's call for an immediate attack on City Hall. They instead decided to send Mackenzie north to investigate public sentiment. At a secret meeting in East Gwillimbury, Samuel Lount, Silas Fletcher, Peter Matthews of Pickering, Nelson Gorham of Newmarket, Jesse Lloyd of King township and James Bolton of Albion township heard Lloyd report on the revolt in Lower Canada. All were delegates to the Constitutional Convention. They decided to set the date for a supportive Upper Canadian revolt on December 7.
