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
The Church was led by the Rev. John Strachan (1778–1867), a pillar of the Family Compact. Strachan was part of the oligarchic ruling class of the province, and besides leading the Church of England, also sat on the Executive Council, the Legislative Council, helped found the Bank of Upper Canada, Upper Canada College, and the University of Toronto.
