The future of the monarchy in Canada

From activehistory.ca, a thoughtful article on a sometimes sensitive topic. As a dual citizen whatever Canada decided about the monarchy I'd have a monarch as long as Britain, or maybe in view of the Scottish referendum I should say England, does.
In any event Canada would likely opt to remain part of the British Commonwealth and, as did South Africa which has it's own head of state, so maintaining a link with the British monarchy.
