So many of my friends that have flown on Canadian airlines with their toddlers (the ones with smaller babies, haven't had issues) weren't permitted to bring the car seat onto the plane. Some were even told 'yes, its permitted', 'yes, that seat meets plane standards' prior to arriving at the airport and then they get there, literally to the gate and have to check it. Can't stand all the confusion, but yes, we will definitely re-evaluate the situation closer to departure.
