Surtsicna has a very good point, and I wholeheartedly. New France was a colony. Colonies are not independent states and thus by definition don't have a Head of State, be it a President or a Monarch. Elizabeth II, for example, is not 'Queen of the Falkland Islands', because no such office exists and the Falklands are not an independent state. Francois Hollande is not 'President of French Guiana', because French Guiana is a French overseas department, and so on. Again; colonies cannot have a Head of State by definition!

Canada after 1867 of course was not a colony, legally had a monarchy separate from that of the UK, and thus 1867 really should be the cut-off point.

'Monarchs who ruled the country that was the colonial power that colonized Canada' is not the same thing as 'Monarchs of Canada'-including the French monarchs and the UK monarchs prior to 1867 makes as much sense as having a list of the British monarchs prior to 1776 on the page 'List of Presidents of the United States'
