Apologies, I have two more questions:
1. If I am flying to the US and then entering Canada via a land border, will the US inquire about my legal status in Canada? If they do, should I present my COPR or my visa stamp along with my work permit?
2. If I leave Canada after receiving my COPR, will my PR card still be delivered to my Canadian address while I am away?
1. US won't care about your legal status in Canada as long as you have a visa, Canadian Border Patrol might ask that question while entering Canada and you just show them your COPR and Visa that's all no need to show your WP as you are already a Permanent Resident now.
2. yes it will be delivered to the mail box of the address that you mentioned during P2.
