Thanks -- that's exactly what I wanted to know

Good point, thanks! I am pretty sure the note is in the PNR as I have verified it with 2 different reservations agents just in case

. If I am not mistaken, at YYZ they use the DCS software provided by the airport authority, so there is always a possibility that the note won't show-up automatically...
