In a moving road vehicle, children whose sitting height is less than 63 cm (measured from the seat to the top of the head) must be securely held in a car seat for children.
As it is mandatory to use a suitable car seat for children, you must read the manufacturer's instructions for the height and weight a given seat can safely accommodate.
Note
To ensure that you choose the right seat and use it properly, you can make an appointment with a child car seat installation and inspection service in your region. Certain charges may apply for installation only.
For regional listings of outlets that offer the child car seat inspection service (by appointment only), consult the Website of CAA-Québec.
