am I assuming you are a Canadian plat holder? Wonder if the kiosk works with a US-based card.

I’ve got the US one, which got me a card for priority last time, but I’m not sure if the benefit technically applies (and is unpromoted), or if the person at the table last time just can’t tell since the cards look exactly the same. Even if the benefit is on the US card, probably hardly worth Amex marketing the benefit for priority security at a single Canadian airport since it likely apply to so few cardholders. So wondering if the kiosk would accept a US card. On the other hand, last time I left YYZ in Oct., Nexus line was not open, and is now, so that line is likely a better bet than priority.
