If your TRV is still valid and has entries remaining/allowed, then that TRV w/passport should be enough for the airline to allow you to board.
What many people don't understand is that once you GET to a Canadian border, the CBSA can use your passport and CoPR (confirmation of PR) document to tell that you are a PR and will let you in.
The issue is getting to the border. Commercial carriers (air, train, boat) don't have that data so they have to see SOME document that you are allowed to enter Canada. That can either be your PR Card (obviously), or if you don't have that yet, then a PRTD, or a passport from a visa-exempt country (if asked you tell airline you are going to visit), or a passport from a NON-visa exempt country WITH a valid Canadian visa.
The airline is not going to interrogate you, they just need to see that you have something that shows you are allowed to enter Canada.
The only possible issue w/ using the passport w/TRV, is if the airline can somehow see in their system that the visa is no longer valid due to you being a PR. That seems unlikely though.
