Buying a child car seat or booster seat
From Transport Canada
It is important to choose the right stage of child car seat for your child. Each province and territory has its own restrictions for child car seat and booster seat use. Your model of seat will also have its own restrictions.
Some child car seats fit more than one stage. It is safest to keep your child in each stage for as long as possible.
It is a good idea to register your new seat with the manufacturer. It is also important to replace the seat if it is damaged, expired, or was in a car involved in a collision.

Learn the four stages of child car seat use
There are four stages of child car seat and seat belt use for children, as shown in the chart below. All car seats are different. Check the manufacturer's manual and the labels on the seat to find out if your child is the appropriate weight and height for the seat.
- Stage 1: Rear-facing seats – use until your child outgrows the car seat's weight/height limits.
- Stage 2: Forward-facing seats – use until your child outgrows the car seat's weight/height limits.
- Stage 3: Booster seats – use until your child outgrows the booster seat's weight/height limits.
- Stage 4: Seat belts – use once your child outgrows the booster seat's weight/height limits.
Stage 1: Rear-facing seats are placed at a 45-degree angle so that your baby's head is supported. This makes it easier for them to breathe. A snug harness will keep your baby safe in a sudden stop or crash.
Keep your child in the rear-facing seat for as long as they are still in the weight/height range of the seat.
Stage 2: Forward-facing seats have harness straps that are narrower than a vehicle seat belt and fit children's small shoulders.
As long your child is still in the weight/height range of the seat itself, you can still safely use the child seat.
Stage 3: Booster seats are designed to allow seat belt use by children who no longer need forward-facing seats. The booster seat positions a child so that the seat belt fits properly over the lap and shoulder.
Stage 4: Seat belts are used when children are tall enough to use a seat belt that is properly positioned over their lap and shoulder without needing a booster seat.

Avoid cross-border shopping for child car seats
The National Safety Mark (sample shown below) indicates that a child car seat is certified to Canadian safety standards, which are different from other standards.
It is illegal to import, sell, or use child car seats and booster seats in Canada that do not have this mark.
Parents are strongly advised to buy a seat only from a Canadian retailer to make sure the seat meets Canada's rigorous regulations for safety. For more information, read Child car seat cross border shopping – what parents and caregivers should know.
Register your child car seat or booster seat
You should register your new seat with the manufacturer after buying it. Registering with the manufacturer is the only way that you will receive notices about any safety recalls affecting the product. There are two ways to register:
mail the product registration card to the manufacturer
visit the website of the manufacturer and register online
Note: You can also access safety recall notices directly on the Motor Vehicle Safety Recalls Database.
Replacement of child car seats or booster seats
If your child has outgrown a seat, replace it with one that fits.
Dispose of your child car seat or booster seat if:
the expiry date on your seat has passed
the seat was in a vehicle that was involved in a collision
even if the seat was empty, it may have been damaged
If the shell or webbing of the seat is torn or damaged, contact the manufacturer to check whether you should replace the seat.
See Safety recalls, notices, and testing for child car seats if you need information on finding recalls or public notices related to your model of seat.
