New Brunswick Car Seat Laws

Each Canadian province and territory has their own laws that govern the use of car seats, booster seats, and seat belts according to the child’s age, height, and weight. The law is the minimum safety standard that can be enforced. You may choose to keep your child rear facing, forward facing, or in a booster seat for longer than these minimums. Check your seat for the height, weight, and age limits.
