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.

Among the more than 150 lawsuits they launched that year, the Bank of Upper Canada, which served the same purpose as the Bank of the United States, launched a suit against Sheldon, Dutcher & Co., a foundry and Toronto's largest employer with over 80 employees in late 1836, bankrupting the company. Not surprisingly, Mackenzie's first plan for rebellion involved calling on Sheldon & Dutcher's men to storm the city hall, where the militia's guns were stored.
