A high back booster seat is the right next step once your child has outgrown the five-point harness on a forward-facing car seat. Kido Bébé carries high back booster seats from Britax, UPPAbaby, Diono, Clek, Cybex, Nuna, and Maxi-Cosi, giving families across Canada and in Montreal a curated, multi-brand range built around proper seatbelt fit. If your child still needs harness support a little longer, our harness-to-booster car seats collection is worth a look first.

In Canada, booster seat use falls under Transport Canada's motor vehicle safety regulations, specifically CMVSS, the Canadian Motor Vehicle Safety Standards, not the American standards many buying guides quote by default. A high back booster adds a backrest and headrest around your child, positioning the shoulder belt across the chest instead of the neck and adding side-impact protection a backless booster cannot offer. Most models secure to the vehicle using the Universal Anchorage System, or UAS in Canada, keeping the seat stable when empty.

Most children move into a booster once they weigh at least 40 lbs (approximately 18 kg) and are at least four years old, having outgrown their harnessed seat. From there, guidance calls for staying in a booster until the vehicle's own lap and shoulder belt fits properly, generally around 4 feet 9 inches (145 cm). The age this happens varies by province, so always check your provincial requirements alongside the seat's own printed weight and height limits.

Look for an adjustable headrest that grows with your child over several years, deep side wings that still work with winter coats and Montreal's cold-weather layers, and a seatbelt guide that keeps the shoulder belt off the neck.
