mmm. I am not a Canadian (American, residing in Arizona), but as my parents are up in BC, I completed my Nexus interview at YVR (converted GE to Nexus since I was crossing the boarder frequently when seeing my parents). So, maybe this is due to my card being issued in Canada? That would be a bummer, I guess if that's the case, I should renew in 2023 in Blaine or some other US based center.
I do see a remote option becoming available, so if I can actually get an appointment, maybe that will solve the issue. Will just have to keep a close eye on it I guess.
