Don't give up quite yet and do not wait to get to YVR. When you check in at YYJ tomorrow morning ask the agent at the counter to add you to the U/G list for AC29. Show the cert to the agent and they should be able to do it without issue.
EDIT: I was going to be working at the time you'll be checking in but my shift just changed and wont be starting until Noon tomorrow, so good luck.
