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
The rebellion led directly to Lord Durham's Report on the Affairs of British North America, and to "The British North America Act, 1840", which partially reformed the British provinces into a unitary system, leading to the formation of Canada as a nation in 1867.
