I got the email at 1st Dec as well, supposed to have and telephone interview between 9:30~12:00 today, but I got a call just now (at 7:30, 2 hours earlier and I was still sleeping....come on this is not as you said in the email, I already consider the time difference between Montreal and Vancouver), and I haven't received coPR yet...
The lady told me to mail back the document once I have it, and someone will contact me for reschedule, but this time it won't be an express landing, but a normal procedure, which means I need to go to the border, do process like everyone else.
I still don't get why they make this so confusing...it just costs me another two weeks of waiting, let alone christmas holidays are coming, gosh I wish to get it done before holidays so much...
