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.

David Gibson, a distinguished land surveyor, was another leader in this community. Like most of his neighbours, Gibson participated in the ill-fated Upper Canada Rebellion of 1837. He was thus charged with high treason and escaped to the United States, where he found employment as the First Assistant Engineer on the building of the Erie Canal.
