yes. Once you get your COPR, you need to exit Canada at the nearest border (most likely US!), and re-enter. WHen you enter, you tell them you want to "land as a PR" and with your passport + COPR, they will complete the procedures. It's quick ( 10 min more or less), and not stressful. If you don't have a US visa, you can just tell them at the border that you don't want to go to the US but you just need to flagpole, and they will do everything necessary.
Good luck,
