Winter Driving Tips for Ottawa Roads: How to Avoid Breakdowns

March 22, 2026|By Ottawa Towing Solutions Team

Ottawa is one of the coldest capital cities in the world, and our winters are no joke. From December through March, drivers face extreme cold snaps that can plunge temperatures below minus 30 degrees Celsius, ice storms that coat every surface in a sheet of glass, and blowing snow that reduces visibility to near zero on the Queensway. Every winter, our trucks respond to hundreds of calls from drivers who got stranded because of a preventable breakdown. Here is how to avoid being one of them.

Install Winter Tires (It Is the Law in Quebec)

Ontario does not legally mandate winter tires, but if you cross the river into Gatineau or anywhere in Quebec, you are required by law to have them installed between December 1 and March 15. Regardless of the legal requirement, winter tires are one of the single best investments you can make for safe winter driving in Ottawa.

All-season tires lose their grip when temperatures drop below 7 degrees Celsius. Their rubber compounds harden in the cold, reducing traction on both dry and wet pavement. Winter tires are designed with softer rubber compounds and deeper tread patterns that maintain grip in freezing temperatures. On a snowy or icy road, the stopping distance difference between winter tires and all-seasons can be several car lengths, which is often the difference between stopping safely and rear-ending the vehicle ahead of you.

Take Care of Your Battery

Cold weather is the number one killer of car batteries. A fully charged battery loses about 35 percent of its cranking power at minus 20 degrees Celsius, and a weak battery may have nothing left to give at those temperatures. Battery boost calls are our most common winter service request by a wide margin.

Here is how to protect yourself:

Have your battery tested before winter begins. Most auto parts stores will test it for free. If it is more than three years old, consider replacing it proactively.
Keep the battery terminals clean and free of corrosion. A wire brush and some baking soda mixed with water will do the job.
If you park outside, consider using a battery blanket or block heater to keep the engine warm overnight. A block heater is a small investment that pays for itself in reliable starts and reduced engine wear.
Avoid short trips in extreme cold. Your alternator needs time to recharge the battery after starting, and short trips do not give it enough time.

Pack a Winter Emergency Kit

If you drive in Ottawa between November and April, you should have a winter emergency kit in your trunk at all times. You may never need it, but if you get stranded on a rural stretch of road or stuck in a highway closure on the 417, you will be glad it is there.

Your kit should include:

A warm blanket or sleeping bag
Extra winter gloves, a hat, and warm socks
A flashlight with extra batteries
Jumper cables or a portable jump starter
An ice scraper and a small snow shovel
A bag of sand or kitty litter for traction
Non-perishable snacks and bottled water
A first aid kit
A fully charged portable phone charger
Road flares or reflective triangles

Prepare Your Vehicle for Winter

Beyond tires and the battery, there are several other maintenance items that deserve attention before winter arrives:

Windshield washer fluid: Switch to a winter-rated formula rated to at least minus 40 degrees. Regular washer fluid will freeze in your lines and leave you with no way to clear road salt spray from your windshield.
Coolant/antifreeze: Have your coolant tested to make sure the freeze point is low enough for Ottawa temperatures. A 50/50 mix of coolant and water protects to about minus 37 degrees.
Wiper blades: Install winter-rated wiper blades. They are built with rubber boots that prevent ice from clogging the joints.
Brakes: Have your brakes inspected before winter. Stopping distances are already longer on snow and ice, and worn brakes make the problem much worse.
Tire pressure: Cold air causes tire pressure to drop. Check your tire pressure at least monthly during winter, and inflate to the manufacturer's recommended level, which you can find on the sticker inside the driver's door jamb.

What to Do If You Get Stranded on the 417

The Queensway (Highway 417) is Ottawa's main east-west artery, and it is where many winter breakdowns happen. If your vehicle breaks down or you lose control on the 417, follow these steps:

Pull as far onto the right shoulder as possible. If you can reach an exit or a service area, do so.
Turn on your hazard lights immediately.
Stay inside your vehicle with your seatbelt on. The shoulder of the 417 is a dangerous place, especially in low visibility conditions. Being inside your car with the seatbelt on gives you the best protection if another vehicle leaves the road.
Call for help. If you have roadside assistance, use it. Otherwise, call a towing company that covers the 417.
If you must exit your vehicle, do so on the side away from traffic. Never stand between your vehicle and the traffic lanes.
Run your engine periodically for heat, but crack a window slightly to prevent carbon monoxide buildup, especially if snow is piling up around your exhaust pipe.

Drive for the Conditions, Not the Speed Limit

This is the simplest advice and the hardest for many people to follow. The posted speed limit assumes dry, clear conditions. When the road is covered in snow or ice, that limit is meaningless. Reduce your speed, increase your following distance to at least four seconds, and avoid sudden acceleration, braking, or steering inputs. If the conditions are truly bad, consider whether the trip is necessary at all. No appointment or errand is worth your life.

Ottawa winters are long, but they are manageable with the right preparation. Take care of your vehicle, pack an emergency kit, and drive cautiously. And if you do end up needing a tow or a boost on a cold Ottawa night, save our number. We have been out in every ice storm, cold snap, and blizzard this city has thrown at us.
