What I'm taking away from that response is that you know quite well that the monarchy have no real power in Canada.

What power do you think they have? What real, tangible things do you think they can they do?

If you don't understand how opening up the constitution could turn into a massive clusterfuck then I'd suggest you do a little research into the controversies surrounding the Constitution Act of 1982 and its passage without the assent of Quebec.

Not exactly our proudest moment as a nation, but we can't just close our eyes and pretend it didn't happen.

That would require the assent of every province due to the ay our constitution is structured, and every indigenous tribe with a treaty signed by the Crown because one party to a treaty can't unilaterally alter the terms like that. That would make it every bit the shitshow that totally removing the Crown would be.

The only way something like this could happen would be if the monarchy tried to pull some bullshit like they did in Australia. That would cause a constitutional crisis of epic proportions and create the political will to remove them entirely. I don't think it's a realistic thing, though. The monarchy know damned well that we're only content to leave this can of worms unopened because they don't interfere with us.

It's unlikely that it would cause the country to collapse, the issue is that it would be a massive boondoggle, cost a fortune, and inevitably fail, all for the sake of making a pointless statement. Why on earth would we want that?

Anyone who thinks ditching the Crown makes sense for Canada is profoundly ignorant of our political system. They have no real authority here and it would cause the biggest inter-provincial clusterfuck in decades as provinces tried to extract concessions for providing their assent. That's not even getting the mess it would cause with indigenous tribes who have signed treaties with the Crown.
