Until 1835, all banks in Upper Canada required a legislative charter; this left them subject to political corruption and manipulation, as was the case with the largest of them, the Bank of Upper Canada. The Bank of Upper Canada was controlled by the Family Compact and used by them to control the province's money supply and trade. Reformers tried several legislative strategies, including attempts to incorporate credit unions such as the Farmers' Storehouse company. This came to an end in 1835 when Charles Duncombe produced a "Report on Currency" for the Legislative Assembly which demonstrated the legality of the Scottish joint-stock bank system in Upper Canada.
