Valid COPR traveling to Toronto from US

Hello I am Indian citizen, we have valid COPR for me, my husband(Indian) and son(US citizen). Planning to travel to Canada by Air. We were not asked to retake any medicals and PCC, but we took an Upfront medical be on safe side when landing. Also, i made reservations for our stay. I would like to know did anyone being an Indian or any non- US citizens, traveled from US with valid COPR to activate/get their PR cards. Please let me know your experience. Thank you
