PRTD - urgent travel

Hi everyone,

I received my ecopr on March 10 and I'm travelling to Norway for 10 days this Monday. My PR card photo and address is currently under revision and it hasn’t even mailed yet.

I know I need a PRTD to board a flight back to Canada. The nearest VAC for me is London.

My main concern is: I'm not sure I want to send my passport to the London VAC because I'm worried I won't get it back in time (or at all before I travel).

My questions:

1. Is there any way to get a PRTD without physically sending my passport? Can anything be done online or digitally?
2. If I have to send my passport, how long does London VAC typically take to return it?
3. One option I'm considering is returning to Canada via the US by land border - I know you don't need a PRTD for land entry. Is this correct and has anyone done this through Buffalo?

Any advice or experience welcome. Thanks!
