Frankly speaking, first time heard like this, seems airline guys dont have clear information and they dont want to take any chances and just lied to you so you can get away, my opinion, before booking the tiket with any different airline, just check with them that you are eligibile to fly, and i am sure you are.
I am in Canada now after the 2nd attempt, here is my story which I also shared on the other thread for anyone who is interested. (My COPR was issued before Mar 18th and valid when I travel)
I tried again 2 days later and I am now in Canada. The check in was still horrible, let me share my story.
So after the first attempt, I cancelled my round trip ticket and purchased a one way ticket and give it another go.
So this time I came prepared, I even had letter of explanation, a letter from my friend that says he will let me stay at his place and so on. But honestly we don't really need all these after we have obtained COPR, especially under express entry.
Again they took all the documents and took them forever (1 hr) to come back to me saying that they are not sure if my entry will be cleared in Canada and hence would like to have me purchase another ticket just in case my entry is denied. At this point, I am quite puzzled because I had a round trip ticket 2 days ago and yet I was denied to board. I bought a ticket anyway because I would need it sooner or later and the price is actually not bad, although I was far from pleased. But the best is yet to come, I was about to get my boarding pass after showing them I bought another one way ticket for return; they said "stop"! I seriously don't know what's going on and someone said that if I have a return ticket then CBSA in Canada would even more likely to deny me entry and ask me to refund the ticket again. By now, I am not sure what to think anymore and by now I am not even sure if it is CBSA that they are corresponding anymore because if it was CBSA then it is way too unprofessional and incapable. Airline helped me refund the ticket and I finally got the boarding pass with a consent form stating that EVA will not be responsible if I am denied for entry in Canada.
FLYING- thinking could it be possible that I get denied entry? Doesn't sound right as I have all the right doc.
Landed in Vancouver, cleared the first custom, didn't ask me anything. Took my COPR to the immigration counter only to find there are 6 officers there chatting and having fun until i ruined their moment perhaps. One of them came to me and took my paper away to process and came back 10 mins later to ask me to fill out the address for PR card and I am good to go. Oh and told me to make sure I self isolate for 14 days. Voila, that's it.
I have no idea what the fuzz is all about at check in, but all is well and I am self isolating as we speak.
I am suspecting that the airline wasn't speaking to CBSA at all but only among themselves, or else its way too unprofessional.
