Thanks!
You do need to enter Canada because the boarding lounge is inside security but there is no immigration/customs to cross to leave (except for US-bound flights). Therefore, if you are not admissible to Canada, you will not be able to access your flight. There is no area where flights are in a transit area outside immigration for overseas destinations. If you are in the boarding lounge, you are free to leave via the security exit and no one is going to stop you - so they stop you before you get there. I would hope.
