Winter in Canada brings freezing temperatures, heavy snowfall, and ice that can damage your home and potentially void your insurance coverage if proper precautions are not taken. Most home insurance policies in Canada require homeowners to take reasonable steps to prevent damage, and failing to winterize your property can result in denied claims for freeze-related damage. This checklist covers the essential steps to protect your home and maintain your coverage before winter arrives.

Heating System and Pipes

Inspect and service your heating system. Schedule a professional inspection of your furnace or heating system before the cold sets in. Most insurers expect homeowners to maintain heating equipment in working order, and a breakdown during winter can lead to frozen pipes and costly water damage claims.

Insulate exposed pipes. Wrap pipes in unheated areas such as basements, crawl spaces, and exterior walls with foam insulation sleeves. According to the Insurance Bureau of Canada, frozen and burst pipes are among the most common and expensive winter claims (IBC, 2026).

Keep your thermostat set to at least 13 degrees Celsius (55 degrees Fahrenheit) if you leave your home. Many home insurance policies in Canada include a requirement that you maintain minimum heat or have someone check your property daily if you are away for more than a specified period (often 48 to 96 hours, depending on your province and insurer). Verify this requirement with your insurer and arrange for a neighbour or property manager to check your home if you will be away.

Shut off exterior water taps and drain garden hoses. Disconnect hoses, drain outdoor faucets, and shut off interior valves that supply exterior taps to prevent freezing and pipe bursts.

Roof and Gutters

Clear gutters and downspouts. Remove leaves, twigs, and debris from gutters and downspouts to ensure proper drainage. Ice dams can form when gutters are blocked, causing water to back up under shingles and into your home. Ice dam damage may be covered under the dwelling portion of your home insurance policy, but prevention is always better than filing a claim.

Inspect your roof for damage. Check for loose, cracked, or missing shingles and repair them before snow and ice accumulate. Heavy snow loads can worsen existing damage and lead to leaks or structural issues.

Remove overhanging branches. Trim tree branches that hang over your roof or power lines. Ice and snow can cause branches to break and damage your home or cause power outages.

Windows, Doors, and Weatherproofing

Seal gaps and cracks around windows and doors. Apply weatherstripping and caulking to prevent cold air from entering and warm air from escaping. This reduces heating costs and prevents ice buildup in vulnerable areas.

Install storm windows or use window insulation kits. Adding an extra layer of insulation helps protect against drafts and reduces the risk of condensation and ice formation on interior surfaces.

Check door sweeps and thresholds. Ensure exterior doors close tightly and that door sweeps are in good condition to keep out snow, rain, and cold air.

Chimney and Fireplace

Have your chimney inspected and cleaned. Creosote buildup in chimneys can lead to chimney fires, a serious risk during winter when fireplaces see more use. Most home insurance policies cover fire damage, but you must take reasonable precautions to prevent fires in the first place.

Install a chimney cap. A cap prevents rain, snow, birds, and debris from entering your chimney and causing blockages or damage.

Walkways, Driveways, and Exterior

Stock up on ice melt and sand. Keep walkways, driveways, and steps clear of ice and snow to prevent slip-and-fall injuries. Homeowners can be held liable for injuries that occur on their property, and liability coverage under your home insurance policy typically requires you to maintain safe conditions.

Check outdoor lighting. Ensure exterior lights are working to improve visibility and safety during the shorter, darker winter days.

Store or secure outdoor furniture and equipment. High winds and heavy snow can damage or blow away unsecured items. Store patio furniture, grills, and garden tools in a shed or garage.

Emergency Preparedness

Test smoke and carbon monoxide detectors. Replace batteries and ensure detectors are functioning properly. Heating system malfunctions during winter can increase the risk of carbon monoxide poisoning.

Prepare an emergency kit. Include flashlights, batteries, a battery-powered radio, non-perishable food, water, blankets, and a first aid kit. Power outages are more common in winter, and being prepared reduces risk and stress.

Know where your water shut-off valve is located. In the event of a pipe burst, shutting off the water quickly can minimize damage.

Verify Your Home Insurance Coverage

Review your home insurance policy. Confirm what winter-related damage is covered and understand any maintenance requirements or vacancy clauses that apply if you leave your home for an extended period. Coverage, exclusions, and requirements vary by province and by insurer, so read your policy wording carefully.

Document your property. Take photos or video of your home and belongings before winter. This documentation can be invaluable if you need to file a claim.

Contact your insurance broker or agent. If you have questions about winterization requirements or coverage for specific winter risks such as ice dams, sewer backup, or overland water (flooding from snowmelt), speak with a licensed insurance broker or agent in your province. The Financial Consumer Agency of Canada recommends confirming coverage details and asking about any endorsements or riders you may need (FCAC, 2026).

Conclusion

Winterizing your home protects your property, reduces the risk of expensive damage, and ensures you meet the maintenance requirements of your home insurance policy. Start this checklist in the fall, well before freezing temperatures arrive. Taking these steps now can prevent costly claims and give you peace of mind throughout the winter season.
