Hey! Sorry to delay, just saw this.
When you called the CBSA and they said your case is non-discretionary, what exactly did you ask them / tell them about your case?
What kind of letters do you have from your professors? I think a letter directly from your school / program is preferable.
Don’t fret too much about your university. They are trying to keep up with all the news from the government, and to be really transparent, many of them don’t seem to really know about this option. I wouldn’t heed their advice if you have a worthwhile case.
To answer your questions: yes, I showed them my AIP but only as a supplement to my case, not as my only reasoning. And no, do not cancel your previous app beforehand, you can do that afterward.
I think because you have in-person activities, your case might work - what type of program are you enrolled in?

Thank you so much for your reply, no worries about timing!
Reading about your case is really a great hope for me!
I am a PhD candidate in the Humanities program at Concordia, but I used to be a visitor scholar last fall, then traveled out of Montreal for a job and got stranded out. Meanwhile, I got accepted as PhD student. Originally I was planning to return to Montreal with my SO, and apply at POE as US citizen. But COVID came and I haven't been able to come back. Therefore, I did call CBSA and the officer said that my case is non-discretionary because, I used to live there and I' am returning home, and my research lab activities are presential.
I do have two letters from my advisers (with the official university letterhead) and even from the Dean of my department informing me that I must be there for lab activities, and the labs have been re-opened. My activities in the lab and with my advisor are related to theater activities and media recordings of residents of Montreal.
My ISO office is advising me to be very careful and a bit discouraging since I don't have an SP or an IRSS final letter. I believe they don't want to disclose info about the number of students who crossed (or might not have information about) US students who did it only with the AIP letter.
I'm really scared about the act of going to the land border because I only have the AIP, along with the other essential documents (even my apartment lease!). I really hope I have an understanding officer like yours.
Thank you for reading and posting about your case!
