Q: When can my child start riding in the front seat of the car?A: Transport Canada recommends keeping all children under 13 years of age in the back seat. This is of particular importance in cars that have air bags in the front seat, as front air bags can cause serious injuries to children. Advanced air bags that use sensors to determine the weight of the person in the front seat CANNOT be relied upon to prevent the air bag from deploying while your child is in the front seat.http://www.seatsforkidscanada.com/FAQ.html
