I would observe that standing your ground against Aeronautics Act is a good way to get into serious trouble. While I don’t disagree with not accepting this mess, if your actions purposely delay your flight, and then you can be offloaded for a very different reason if you cause a stir and the crew doesn’t want you on board anymore.

The solution of just accepting or bringing mattresses just feeds the problem… Write to AirCanada, don’t accept their compensation, and make a stir this way, will be more affective and start to impact the bottom line.
