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 Rebellion
A number of the rebels were hanged including Samuel Lount and Peter Matthews, others were shot. Their deaths were a strong motivation for the continuing Patriot War. Many more prisoners were transported, but most were pardoned, e.g. Enoch Moore (Loyalist turned rebel). A general pardon (for everyone but Mackenzie) was issued in 1845, and Mackenzie himself was pardoned in 1849 and allowed to return to Canada, where he resumed his political career. Mackenzie was strongly disillusioned after his time in the United States, writing to his son that "after what I have seen here, I frankly confess to you that, had I passed nine years in the United States before, instead of after, the outbreak, I am sure I would have been the last man in America to be engaged in it." In later life however, Mackenzie advocated annexation of Canada by the United States.
