This article explains why and how some Canadians have asserted a right to possess firearms from the late nineteenth century to the early twenty-first century. It demonstrates that several late-nineteenth-century politicians asserted a right to arms for self-defence purposes based on the English Bill of Rights. This “right” was forgotten until opponents of gun control dusted it off in the late twentieth century. Firearm owners began to assert such a right based upon the English Bill of Rights, William Blackstone, and the English common law. Their claims remained judicially untested until recent cases finally undermined such arguments.
