I think most Canadians would agree. We just don’t care about it enough to try to change it because if something came up where we actually needed to force the issue we could fairly easily, and it has it’s own benefits in being closer allies with other Commonwealth countries.

It’s not the citizens having no confidence in the government, it’s the other members of parliament. If the government cannot get a majority of MPs to support their bill, they have lost the confidence of parliament, which will trigger and election (or technically could have the GG assign government to another party who DOES have the confidence of parliament, though to my knowledge that has never happened, but it is a tool in their toolbox).

Our federal elections are run by Elections Canada, which reports to parliament as a whole, not to the Government of Canada. It is a non-partisan agency. We have a similar setup in the provinces with each having their own provincial election agency. I am unsure how it is handled in the territories.

Pretty much. If the current party in power is not able to gain sufficient support for confidence motions (there are a number of things that qualify as a confidence motion, the budget being a big one) Then the Governor General (the official representative of the King / Queen) can offer control to another party if they ARE able to gather that support, or simply call an election.

Technically the (currently King) is our head of state, but for most functions our Prime Minister fills that role. The current government losing confidence of parliament is one of the functions where the King still holds de facto power in addition to de jure power.

Note that while they are titles held by the same person, the titles of King of Canada and King of the United Kingdom are legally distinct, and while referring to his role in Canadian governance, it is appropriate to refer to Charles III as King of Canada specifically, and inappropriate to use his other titles in that context. Mostly because the King of the United Kingdom has no role in our government, but the King of Canada does.
