All children’s car seats and booster cushions now sold in Canada have an expiry or useful life date on them. Manufacturers do this to warn buyers not to use them too long. People using children’s car seats and booster cushions past their expiry or useful life date, do so at their own risk.

Manufacturers give an expiry or useful life date because over time:

• frequent use and exposure to sunlight can damage plastic;
• labels on the products fade or become hard to read;
• safety instructions have likely been lost;
• food, cleaners, drinks and other materials that have been spilled or used on webbing, buckles, adjusters and other parts may prevent them from working safely;
• the history or condition of the car seat or booster cushion becomes hard to check (was it in an accident, was it stored in a place or in a way that caused damage to parts, etc.?);
• safety regulations and standards may have changed, so safer products may now be on the market; and
• second or third hand owners may not get product recall notices if safety problems arise.

In Canada, all provinces and territories require infants and toddlers to be buckled up in the appropriate car seat. Several provinces also require booster cushions for children who have outgrown a child car seat but are too small for a regular seat belt. The provincial and territorial laws also say that the children's car seats and booster cushions must be certified to Canada Motor Vehicle Safety Standards and must be used according to the manufacturer's instructions. If you don't, or if you use them past their expiry or useful life dates - you may be found guilty of breaking the law.
