Debate on the monarchy in Canada
Debate between monarchists and republicans in Canada has been taking place since before the country's Confederation in 1867, though it has rarely been of significance since the rebellions of 1837. Open support for republicanism only came from the Patriotes in the early 19th century, the Red River Métis in 1869, and minor actions by the Fenians in the 19th century.
