@Navitaly @matteosc I am in the same situation. I got my eCOPR on Jan 11th. I don't have my PR card but looks like its going to take atleast a couple of months from eCOPR date. My TRV was renewed recently on Jan 6th and is valid until 2029. I have travel plans to leave the country on Jan 30th. I cannot postpone or cancel this. I am hoping the validity of my visa will allow me to enter Canada. The timing is coincidental where both TRV and eCOPR arrived around the same time. I did not plan this and considering I don't have a natural travel document as a PR, I am hoping my TRV can fill the gap. It sounds fair to me but cannot find much documentation online.
If your new PR card isn’t ready before you leave, you can still travel but you need a permanent resident travel document (PRTD) to return to Canada by commercial vehicle. You can only apply for a PRTD from outside Canada.
