The 30-second checklist (save this)

• Dress your child in thin, warm layers (fleece is perfect), not a puffy snowsuit.

• Buckle the harness snug so you can’t pinch the strap at the collarbone.

• Add warmth over the straps: blanket, sweater, or a coat worn over the top after buckling.

• For infant seats, use a cover that goes over the shell like a shower cap—nothing behind your baby or under the straps.

• If your child faces the front, always attach the top tether strap in your vehicle.

• Use seats with the Canadian safety mark (the round maple leaf).

Why big puffy coats are a problem

Big coats create hidden space under the straps. In a crash, the coat squishes down and the straps can be too loose. Thin layers keep your child warm and let the straps do their job.

What’s safe to add (and what to skip)

Usually safe

• A blanket placed over your child after you buckle.

• A warm sweater or coat worn on top of the straps like a blanket.

• Infant seat covers that go over the seat rim and do not sit behind your baby or thread through the straps.

Skip these

• Anything that goes behind your child’s back or under the straps (bunting bags inside the seat, unapproved inserts, cushiony strap covers).

• Snowsuits that make you loosen the straps to get them to buckle.

Easy winter routines that help

• Pre-warm the car while you’re loading.

• Keep a blanket by the door for the walk to the car; remove it once the car is warm.

• With toddlers, buckle first, then put their coat on backwards over the straps like a cape.

• Keep a small bin in the car: spare mitts, a hat, an extra fleece, and a spare blanket.

Canada-only basics (quick and important)

• Look for the Canadian safety mark on the seat or label. That’s your “yes, this is approved here.”

• When your child faces the front, the top tether strap must be hooked to the anchor in your vehicle.

• Follow the seat’s manual for strap height and weight limits (they vary by model).

• If you’re unsure, book a car-seat check with a trained technician near you. It’s friendly, fast, and worth it.

Quick fixes to common problems

• “My child looks cold without the snowsuit.” Try a long-sleeve onesie, a fleece layer, warm socks, and a hat. Buckle snug, then add a blanket or the coat over the straps.

• “The straps feel tight over a sweater.” Remove one layer and tighten until you can’t pinch the strap at the collarbone.

• “We walk outside to the car and it’s windy.” Use a blanket for the walk and an over-the-seat style cover on infant seats to block wind. Remove extra layers once the car is warm.

Tiny FAQ

Q: Can my child wear a winter coat in the seat?

A: Only if the straps still fit snug without loosening. If you must loosen the straps, the coat is too bulky. Buckle first, then put warmth on top.

Q: Are stroller footmuffs safe in the car seat?

A: Footmuffs and bags that go inside the seat aren’t safe in the car. Save them for the stroller. Use blankets and over-seat covers in the car instead.

Q: What about second-hand or imported seats?

A: Use seats that have the Canadian safety mark and are within their use-by date. Seats meant for other countries may not be legal here.

A dad’s wrap-up

Canadian winters are no joke—but you’ve got this. Think: thin layers on, straps snug, warmth on top. A few small changes make the ride safer and still cozy. If you want a second set of eyes, a local car-seat check is the most reassuring fifteen minutes you’ll spend all season.
