If your upgrade doesn't clear before you check in, you can transfer yourself to the departure waitlist at the airport when you do check in - either using OLCI or by phoning after you've checked in to make sure you've been transfered.
If you are still waitlisted before doing OLCI, you won't be able to check in on-line unless you remove yourself from the waitlist, check in, then add yourself to the departure waitlist.
Good luck.
The OP is not talking about the certificate upgrade process. S/he has used points for a Business Class ticket, but 2 segments only had Economy availability.
There is not an automatic upgrade process for these situations. You must constantly look for Business inventory and then call into Aeroplan to make the free change. If you are an ExpertFlyer user, you can set alerts to notify you when space becomes available.
If by the day of departure you still do not have a Business seat, you can be put on the standby list at the airport. There has been no comfirmation, but it's thought that Reward tickets have a lower priority than status pax using certs to upgrade.
Good luck!
