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 next wave of organised Reform activity emerged in the 1830s through the work of William Lyon Mackenzie, James Lesslie, John Rolph, William John O'Grady and Dr Thomas Morrison, all of Toronto. They were critical to introducing the British Political Unions to Upper Canada. Political Unions were not parties. The unions organised petitions to Parliament.
