Water Damage Is Now Canada's Biggest Home Insurance Risk

When most homeowners think about insurance claims, they often picture a house fire, a major storm, or a break-in. While those risks still exist, water damage has quietly become one of the most common and costly home insurance claims in Canada.

From heavy rainfall and flooded basements to burst pipes and sewer backups, water-related losses are increasing every year. In fact, water damage now accounts for a significant portion of home insurance claims across the country, costing homeowners, insurers, and communities billions of dollars annually.

As weather patterns become more unpredictable and extreme weather events become more frequent, understanding your home’s water damage risks has never been more important.

Why Are Water Damage Claims Increasing?

Several factors are contributing to the rise in water damage claims:

Extreme Weather Events

Across Canada, homeowners are experiencing more intense rainstorms, flash flooding, and severe weather than ever before. A sudden downpour can overwhelm municipal drainage systems and cause water to enter homes through foundation cracks, windows, or basement entrances.

Aging Infrastructure

Many homes and municipal water systems are aging. Older pipes, sewer systems, and drainage infrastructure can be more vulnerable to failure, increasing the likelihood of water-related losses.

Higher Repair Costs

The cost of restoring a home after water damage continues to rise. Water can quickly damage flooring, drywall, furniture, electronics, and personal belongings. In addition to repairs, homeowners often face expenses related to mold remediation and temporary living arrangements while repairs are completed.

Common Types of Water Damage

Not all water damage is the same, and not every type of loss is covered under a standard home insurance policy.

Some of the most common causes of water damage include:

Sewer backup
Overland flooding
Burst or frozen pipes
Roof leaks
Appliance failures
Sump pump failures
Water entering through foundation cracks

Coverage for these risks can vary depending on your policy and endorsements. That’s why it’s important to review your coverage regularly with your insurance broker.

How Can Homeowners Reduce Their Risk?

While no home is completely immune to water damage, there are several steps homeowners can take to help prevent costly claims.

Maintain Your Home

Regularly inspect your roof, eavestroughs, downspouts, and foundation for signs of wear or damage. Addressing small issues early can help prevent major problems later.

Keep Water Away From Your Foundation

Ensure downspouts direct water away from your home and that the grading around your property slopes away from the foundation.

Test Your Sump Pump

If your home has a sump pump, test it regularly and consider installing a battery backup system to help protect your home during power outages.

Consider Water Detection Devices

Smart water sensors and leak detection systems can alert homeowners to leaks before they become major losses. Some insurance companies may even offer discounts for homes equipped with these devices.

Cottage and Seasonal Property Considerations

For many Ontario families, summer means spending time at the cottage or seasonal property. Unfortunately, cottages can be particularly vulnerable to weather-related damage because they are often unoccupied for extended periods.

Before heading away, make sure your property is secure, inspect trees around buildings, and understand any policy requirements regarding property checks and maintenance.

It’s also a good opportunity to review whether your cottage insurance reflects any recent renovations, additions, or increased property values.

Do You Have the Right Coverage?

One of the biggest misconceptions homeowners have is that all water damage is automatically covered by home insurance. The reality is that different types of water losses may require specific endorsements or additional coverage options.

As weather-related risks continue to evolve, it’s important to review your policy to understand:

What water damage coverages you currently have
Any coverage limits or exclusions
Whether additional protection may be beneficial for your home and location
