Which policies implemented by the royal family in the last ~50 years do you think are responsible?
The King doesn't need to get his hands dirty in implementing policies: he has prime minister for that. What the king does is he vetoes policies he doesn't like, without explaining his reasons to PM. So I'd reframe your question as "what hasn't been done in the past 50 years?"
I can't tell if you're joking or not. That's not how the Canadian system works.
Lol you speak English that means England owns Canada. I know you are acting smart and speaking like a jerk but research reality and you will realize the sun still does not set for the British empire which is the Romans. They own America also.
