Reform movement (pre-Confederation Canada)
In Upper Canada (Ontario), the Reform movement was formed in opposition to the Family Compact. It was led initially by William Lyon Mackenzie, who became the principal figure in the Upper Canada Rebellion of 1837. Mackenzie went into exile as a result of the failed rebellion. The uprising led to the 1839 Durham Report, which recommended responsible government and the union of Upper and Lower Canada as a means of assimilating Francophones. Only the union of the Canadas was to be immediately implemented.

The Upper Canada Central Political Union was organised in 1832–33 by Dr Thomas David Morrison (mayor of Toronto in 1836) while William Lyon Mackenzie was in England. This union collected 19,930 signatures on a petition protesting Mackenzie's unjust expulsion from the House of Assembly by the Family Compact.
