Choosing a child car seat or booster seat

A child’s developmental stage, weight and height can help determine what type of child car seat is best suited for them:

Forward-facing child car seat

Rear-facing child car seat, if the manufacturer recommends its use

Your child can use a seatbelt alone when they reach any of the following milestones:

Follow recommendations from the manufacturer

It’s safest to keep your child in a child car seat or booster seat until they reach the maximum weight and height limits of the child car seat.

Most child car seats do not allow the use of aftermarket products and advise to not dress the child in bulky clothing or sports gear as it can compromise the fit of the harness.

Always follow the recommended use set out by the manufacturer.

Buying a child car seat

When purchasing a child car seat or booster seat, check that it has:

Installing a child car seat

For all child car seats, read the manufacturer’s instruction manual and your vehicle owner manual for proper use and installation.

Your child can remain in a rear-facing child car seat until they outgrow the weight and height limits. When switching to the next stage of child car seat, check that the child meets all the minimum requirements outlined by the manufacturer.

Rear-facing and forward-facing child car seats

  1. Place the child car seat in the back seat of the vehicle away from active airbags.
  2. For rear-facing seats, angle the seat according to the sticker or level indicator on the side or base of the seat. Use the appropriate recline level set out by the manufacturer.
  3. Feed the seatbelt or universal anchor system ( UAS ) through the appropriate belt path of the child car seat. Fasten it. There should be no more than 2.5 cm (1 in ) of movement at the belt path. Be sure to check the UAS weight limits in the vehicle owner’s manual and the child car seat manufacturers instruction manual.
  4. Use the harness slots to position the straps: Check that the straps are straight and do not twist or fold. The harness should be snug so that you can’t pinch any excess webbing.
  5. For forward-facing child car seats, fasten the top tether strap, which is located on the rear of the child car seat, to the appropriate anchor point in the vehicle.
  6. Center the chest clip on the harness at the child’s sternum (armpit level).
  7. Each time you place your child in the child car seat, check that the installation is still secure. Tighten the harness straps again if needed. If you are using a rear-facing child car seat with a base, make sure the child car seat latches into the base every time.

Booster seat

It’s safest to let the child outgrow the child car seat before moving to a booster seat. Follow these steps to properly use your booster seat:

  1. Only use a booster seat in a vehicle seat position that has both a lap and shoulder seatbelt.
  2. Place the booster seat in the back seat away from an active airbag.
  3. Adjust the lap and shoulder belts. The shoulder strap lies centred across your child’s shoulder (not the neck or face) and middle of the chest. The lap belt crosses low over the hips (not stomach). Do not use seatbelt adjusters.
  4. Make sure your child's head is supported by the top of the booster seat, the vehicle seat or the headrest.
