Most corp contracts that I know of specify price breaks and not upgrades. The fact that your ticket was booked & paid for by a Canadian company likely does not increase your chances for upgrade. As Academic points out, it's really more a function of fare class and certificate you use.
As you are not an Aeroplan Elite or SuperElite member, I don't think you'll be able to upgrade short of paying the fare difference. You should however be able to collect the points assuming you are somehow associated with *A.
