... okay Travelocity.ca lets me specify preferred times and is reasonable. But for YYZ-YUL, if I say 7:00pm, it only offers 9:00pm. If I say 6:00pm, it only offers 9:00pm!

If I just look for a one-way fare on ac.com, there are flights in Tango at 6:00, 6:30, 7:00, 8:00, and 9:00. 6,7, and 8 are expensive but the others are <$100.


... Expedia.ca offers nothing after 6:00pm, perhaps enforcing the (wrong) 4hr rule, but still offers departures from YYZ as early as 7:30am!
