Agree, I think I'm in a very unique boat here. I'll probably end up doing what you advised. As according to this:Would personally not reply until you have left and entered Canada and hope everything goes well. Nothing is going to get done by next week because it is a long weekend and it usually takes weeks before anyone reads the responses. If you indicate that you are out of Canada you may then be processed as if you are outside Canada for your landing. They may have changed the process and instead of sending you virtual landing (and sometimes confirming you are in Canada first) you may now need to confirm that you are in Canada before you are a full PR in the system and your ETA gets cancelled. It is hard to know. Your timing is very unfortunate but not very common and virtual landings are relatively new.
I have a Confirmation of Permanent Residence (CoPR) and will travel to Canada. Do I need an eTA? (cic.gc.ca)
"No. If you are from a visa-exempt country and have a Confirmation of Permanent Residence document, you don’t need an eTA. However, if you haven’t received this document before your planned travel to Canada, you will need to apply for an eTA."
According to this it should be fine, though the last paragraph on this page does contradict the first one... Wish they would pick up the phone...!
In any case bottom line is this can't mess with the PR approval at this point, right? It's just an inconvenience for me in terms of getting back and/or being stuck out of Canada until it's resolved? Worst case I fly to the USA and drive over.
