As per the link I posted above "For flights between Toronto Pearson and JFK, LaGuardia and Newark airports" ... so YUL is not supposed to allow a free standby.
That being said I frequently see agents bend things a bit when it makes sense for Air Canada. Rapidair free standby for example applies YYZ-YOW and YYZ-YUL but technically not YUL-YOW ... but I've never had an issue standing by on an earlier flight on fares that would normally not allow it.
When looking at my confirmation that I received upon booking, I see the following. It was also shown in the AC app for my booking. Perhaps the site needs to be updated or there was a change after I booked.
Same-day standby at the airport is available: on flights between Toronto and Montréal or Ottawa, on flights between
Calgary, Edmonton and Vancouver, as well as on flights between Toronto Pearson (YYZ) and LaGuardia (LGA), John F.
Kennedy (JFK) or Newark (EWR) airports (connecting flights excluded).
