This is how Parliamentary and democratic conventions are made in our parliamentary system. A clear statement by the House, after a clear abuse. The House has spoken, and the Crown and its counsellors must now so govern themselves, except at their peril.
In future, a Prime Minister who advises the Governor-General to padlock our Parliament in order to avoid accountability on a great public issue (as opposed to a routine proceeding) is in violation of a direct order from Canada’s only legitimate and elected democratic body — the House of Commons.
In future, a Governor-General who accepts such advice is therefore inviting a wide debate about the future utility of her office — which would also raise fundamental issues about the future of the Crown in Canada.
