would seem to suggest no Nexus kiosk / gate arriving YTZ. However it seems from the discussion at length in this thread we’ve concluded that northbound air entry using Nexus card is theoretically fine everywhere per the regs, not just at specified airports with kiosks. (I thought I remembered using an old-style iris scan Nexus kiosk when last arriving there long ago, but I use YYZ much more often, so that distant memory might be totally wrong.) In any event, at an explicitly participating airport like YYZ or YOW, it seems like CBSA is fine with entry into Canada on Nexus card alone, and it’s just Porter’s policy that is not.
