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.
Rebellions of 1837–1838
After the rebellions died down more moderate reformers, such as the political partners Robert Baldwin and Louis-Hippolyte Lafontaine, gained credibility as an alternative voice to the radicals. They proved to be influential when the British government sent Lord Durham, a prominent reformer, to investigate the cause of the troubles. Among the recommendations in his report was the establishment of responsible government for the colonies, one of the rebels' original demands (although it was not achieved until 1849). Durham also recommended the merging of Upper and Lower Canada into a single political unit (the Act of Union), which became the nucleus for modern-day Canada. More controversially, he recommended the government-sponsored cultural assimilation of French Canadians to the English language and culture. In fact, the merging of the Upper and Lower Canada was intended to take any form of self-government away from the French Canadians, forcing them into becoming a smaller part of the new, larger, political unit.
