Winter bike commuting is practical when riders plan for changing surfaces, limited daylight, cold exposure, and delayed snow clearing. Winter bike commuting means using a bicycle for transportation during cold, snowy, icy, or dark conditions—not simply riding in low temperatures. Toronto's winter counts show about 20% of peak-summer cycling continues, including roughly 1,200 daily riders on Richmond and Adelaide streets and 1,000 on Bloor Street, according to the City of Toronto's winter-cycling information.

How should you plan a winter commute?
Choose a primary route that receives regular snow clearing, then identify an alternative. Toronto clears bikeways after 2 centimetres of snow, but each plowing round takes about eight hours, and several rounds may be needed. Check the route shortly before leaving.
A path that was safe in the morning may become rutted, slushy, icy, or narrowed by snow later in the day. Postpone the trip during a winter Storm Warning. The National weather Service says snow, ice, sleet, or blowing snow can make travel difficult or impossible; the decision depends on hazards, not a universal temperature cutoff. See the National Weather Service winter-weather guidance.
- Confirm the route is cleared.
- Allow extra time for slower surfaces.
- Keep an alternative route available.
- Turn back if conditions become less stable than expected.
What clothing works best?
Use a close-fitting, breathable base layer under waterproof outer clothing. This combination helps manage sweat while limiting exposure to wet snow, rain, and road spray. Keep loose fabric away from the drivetrain.
Trouser legs, scarves, straps, and other garments can catch in the chain or other moving parts. Protect the areas that become uncomfortable first, such as hands, feet, ears, and face. Clothing should allow normal steering and braking, and it should remain manageable when you enter a heated building.
How can you improve traction and prevent snow buildup?
Lower tire pressure only to the low end of the range printed on the tire sidewall. This can increase contact with the surface, but going below the recommended range raises the risk of damaging the tire or rim. Leave enough clearance around the tires and fenders for snow.
Tight fender gaps can clog as wet snow packs into the space, potentially stopping the wheel. Inspect the bike after wet or salty rides. Remove packed snow before it hardens, and check that the brakes, wheels, chain, and shifting still operate normally before the next trip.
What should you do on ice and in darkness?
If you encounter black ice, steer straight, avoid pedaling and braking, and allow extra stopping distance. Braking or making a sudden movement can initiate a skid and cause a fall. Use a white front light, red rear light, and reflectors when riding in darkness or poor visibility.
Lights make the bicycle easier to detect, but visibility equipment cannot overcome a distracted driver. A correctly fitted helmet remains essential on every ride. The National Highway Traffic Safety Administration reported 1,103 bicyclists killed in U.S. traffic crashes in 2024 and advises wearing a properly fitted helmet before each ride, as described in its bicycle-safety guidance.
When is the cold itself too dangerous?
Check wind chill as well as air temperature. Wind removes heat from exposed skin faster, so a calm-looking thermometer reading may underestimate the risk during a fast ride.
For example, the National Weather Service lists a wind chill of −19°F when the air temperature is 0°F and wind speed is 15 mph; exposed skin can freeze in 30 minutes under those conditions. Use the National Weather Service wind-chill chart when deciding whether exposed skin can remain protected. Cover exposed skin, shorten the trip, or choose another form of transportation when cold, wind, ice, or visibility makes control and protection unreliable.
