Yes, car seats expire, typically 6 to 10 years from their manufacture date. This isn't a marketing ploy; it's a critical safety measure. The primary reasons are the degradation of plastic and other materials over time due to temperature fluctuations and UV exposure, which can weaken the seat's structural integrity in a crash. Additionally, safety standards and technology improve, meaning an older seat may not offer the same level of protection as a current model.
The most direct way to check is to look for a printed expiration date or manufacture date on the seat itself. Check the back, bottom, or sides of the plastic shell, or on a sticker with the model number. The date might be explicitly labeled "Do not use after..." or listed as the manufacture date, which you then add the expiration period to. If you can't find it, your owner's manual will have the location and the seat's specific lifespan.
Never use a car seat that is expired, has been in a moderate or severe crash, is missing parts, or has a history of recalls. Disposing of an expired seat properly is key to preventing its reuse. Render it unusable by cutting the harness straps, and check with your local municipality for recycling programs that accept plastics.
| Car Seat Brand | Typical Expiration Period (Years) | Common Location of Date Stamp |
|---|---|---|
| Graco | 6 - 10 | On the plastic shell, often on the back or bottom. |
| Britax | 6 - 10 | Sticker on the back or bottom of the seat. |
| Evenflo | 6 - 10 | Imprinted on the plastic shell or on a sticker. |
| Chicco | 6 - 8 | Printed on a label on the side or back of the seat. |
| Safety 1st | 6 | On a sticker on the back of the seat. |
| Clek | 9 | Embossed on the back of the shell. |
| Diono | 6 - 10 | On a sticker on the side or back of the seat. |
| Peg Perego | 5 - 8 | On a label on the back or bottom of the seat. |
| Maxi-Cosi | 6 - 9 | Printed on a sticker on the base or shell. |
| UPPAbaby | 7 - 10 | Embossed on the plastic shell or on a label. |

Check the sticker on the back or bottom of the seat—it should say "Do not use after" followed by a date. If it just has a manufacture date, add 6 to 10 years; that’s the standard expiry. No date? Dig out the manual or contact the manufacturer directly. It’s not worth the risk. The plastics get brittle and can crack. When it’s time, cut the straps and toss it so no one else uses it.

As a parent who just went through this, the date can be tricky to find. We had to turn our convertible seat completely over and found it embossed in tiny numbers on the plastic shell. It felt like a treasure hunt. I also learned that expiry isn't just about wear and tear; it's because the safety standards from ten years ago are different today. It’s a pain to replace a seat that looks fine, but knowing it’s about updated crash protection made it an easy decision.

Think of it like the expiry date on food in your pantry. The materials in the car seat—the plastic shell, the foam padding, even the harness straps—break down over time. Sunlight and hot/cold cycles speed this up. In a collision, an expired seat might not perform as designed, putting your child at greater risk. The expiration date is the manufacturer’s guarantee that the seat will function correctly up to that point. It's a non-negotiable safety checkpoint.

Beyond the date stamp, there are other red flags. If you’re getting a hand-me-down or used, you must check three things: the expiry date, the recall history (search Transport Canada’s database), and that it has all its original parts and the instruction manual. If any of these are a "no," walk away. A seat’s history is unknown, and even a minor fender bender can compromise its integrity. Your child’s safety is the one area where "new" is always better.
