http://www.aircanada.com/en/aeroplan...des/eupgrades/eUpgrade waitlist requests are carried through until flight departure. If your waitlisted upgrade request does not clear before you check in, it is automatically transferred to the airport upgrade standby list for clearance at the gate.
But you'll still need to wait until your booking window (2/4/7 days) before you request the upgrade.
