This means that the Queen’s Coronation Oath is central to the whole question of oaths?
Yes. We take oaths of parliamentary loyalty, of general allegiance, or of citizenship to our Sovereign, the head of our national family, because she has first taken an oath of loyalty to us, her people. The oath of citizenship is a reciprocal oath because it is really only one half of the relationship between subject and sovereign, the other half being the Queen’s oath to her subjects. Canada itself, except through its personification in the Queen, cannot take an oath to its people so an oath to Canada is a one-way imposition that improperly restricts the freedom of Canadians.
