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.
Upper Canada
Although the province is frequently referred to as "English Canada" after the Union of the Canadas, and its ethnic homogeneity said to be a factor in the Upper Canada Rebellion of 1837, it should be noted that there was range of ethnic groups in Upper Canada. However, due to the lack of a detailed breakdown, it is difficult to count each group, and this may be considered abuse of statistics. An idea of the ethnic breakdown can be had if one considers the religious census of 1842, which is helpfully provided below: Roman Catholics were 15% of the population, and adherents to this religion were, at the time, mainly drawn from the Irish and the French settlers. The Roman Catholic faith also numbered some votaries from amongst the Scottish settlers. The category of "other" religious adherents, somewhat under 5% of the population, included the Aboriginal and Metis culture.
