Why Did My Home Insurance Go Up in Ontario? Explained

If you’ve opened a home insurance renewal notice recently and done a double-take at the number, you’re not alone. “Why did my home insurance go up?” Ontario homeowners have been asking that same question. The short answer is that several powerful forces are converging at once, and most of them are not going away anytime soon.

At McDougall Insurance, we believe informed homeowners are better prepared homeowners. So let’s walk through exactly what’s happening, why your premiums are climbing, and what you can actually do about it.

How Much Have Home Insurance Premiums Actually Gone Up?

The numbers tell a striking story. The average home insurance premium in Ontario has increased by nearly 38.9% over the past five years, which is a pace far above overall inflation. Zoom out to a decade, and the picture is even sharper: Ontario’s home insurance premiums have jumped 84% between 2014 and 2024, while general consumer prices grew by just 28% over the same period.

More recently, average premiums in Ontario rose 7.15% in 2025 compared to 2024, more than triple the province’s 2.3% inflation rate that year, and above the national average increase of 5.3%. In dollar terms, Ontario homeowners are now paying approximately $519 more per year than they were a decade ago.

These aren’t arbitrary hikes. The rising insurance premiums reflect real and significant changes in the risk landscape, from catastrophic weather events to the soaring cost of building materials. Let’s break each factor down.

More recently, growth has begun to moderate, but not reverse. Home insurance premiums in Ontario increased by roughly 2–5% in 2026, depending on the dataset, following a sharper 7.15% jump in 2025. While the pace has slowed, premiums continue to rise faster than general inflation, reinforcing a long-term upward trend.

Extreme Weather Events and the Growing Cost of Climate Change

No single factor has done more to drive rising insurance premiums in Ontario than the increasing frequency and severity of extreme weather. The insurance industry is dealing with a fundamentally different risk environment than it was even a decade ago.

2024 was the costliest year on record for weather-related insured losses in Canada, totalling $8.5 billion to $9.4 billion. To put that in perspective, the annual average of insured losses between 2001 and 2010 was $701 million. The number of catastrophic weather events in Canada has increased significantly compared to previous decades, with their financial impact quadrupling on average.

Every year since 2020 has ranked in the top ten worst years for insured losses from extreme weather in Canada. This is not a blip; it’s a sustained trend that insurance companies are now pricing into their models.

Ontario has felt this firsthand. In the summer of 2024, flash floods swept through the Greater Toronto Area, resulting in approximately $940 million in insured damages alone. Events like these cause more serious damage and generate more costly insurance claims, costs that are ultimately reflected in the premiums paid by homeowners across the province.

After a record-breaking 2024 that saw insured losses reach as high as $9.4 billion, 2025 brought some relief, but not a return to normal. Severe weather still caused more than $2.4 billion in insured damage, making it one of the costliest years on record and highlighting how elevated baseline risk has become.

Flooding: Ontario’s Costliest Threat

Flooding has become the most damaging natural hazard in Canada, causing average annual losses of about $800 million over the last decade. Overland flooding is defined as when water enters homes through doors, windows, or cracks in the foundation, and it is the single most common and costly natural disaster in Canada.

Yet only about 55% of Canadians carry overland flood insurance coverage, leaving a significant portion of homeowners financially exposed. For those living near flood-prone waterways or in high-risk areas around Lake Ontario and its tributaries, the cost of repairing a basement after flooding can reach at least $43,000 out of pocket without the right coverage.

For homeowners who do file a claim, the financial impact carries forward. A single water damage claim can raise premiums for homeowner’s insurance by an average of $376 annually in Ontario. It’s a reality that makes prevention and the right flood coverage all the more important.

Hailstorms, Wildfires, and Wind Events

Flooding isn’t the only culprit. The insurance industry attributes rising premiums to climate change and climate-related disasters, including wildfires, hailstorms, and severe wind events. A single wind-hail claim adds an average of $386 to the annual home insurance premium for a 2,500-square-foot home in Ontario.

As severe weather becomes more frequent and more intense, insurers face mounting claims costs, and those costs are inevitably passed along through higher premiums.

Rising Building Material Costs and the Construction Industry

Even setting aside extreme weather, the cost to repair or rebuild a home has risen dramatically. The cost of repairing weather-damaged property in Canada has surged by 485% since 2019, a figure that captures just how much more expensive home repairs have become.

The cost of residential building construction in Canada soared by 66% since 2019, significantly outpacing the 19% general inflation rate over the same period. Building materials like lumber, steel, and concrete all saw sharp price increases during and after the pandemic, driven by supply chain disruptions and surging demand.

Tariffs on imported materials have also added to the cost of construction materials, particularly on steel and lumber crossing from the United States. These price pressures from tariffs further influence home insurance rates by making even routine repairs more expensive to complete.

Labour Shortages in the Construction Industry

A shortage of skilled labor in the construction industry is driving up the costs of home repairs and renovations across Ontario. When there aren’t enough qualified tradespeople to handle the volume of work, projects take longer and cost more. Insurance companies account for these higher claims costs when setting their premium rates.

Statistics Canada data have documented these rising building costs consistently over recent years, and the construction industry shows little sign of the labour supply catching up with demand in the short term.

Inflation, Reinsurance, and the Bigger Economic Picture

Inflation is causing insurance companies to adjust their premium rates to keep up with the rising cost of living and reconstruction. When everything from labour to materials to equipment costs more, the amount an insurer must pay to settle a claim goes up, and that directly feeds into higher premiums for policyholders.

There’s another layer most homeowners aren’t aware of: reinsurance. Canadian insurers buy their own reinsurance to cover massive disasters, and global reinsurance rates have jumped 10% to 40% recently. Reinsurance is essentially insurance for insurance companies, and when those costs rise, they flow through to the premiums you pay.

Insurance premiums have grown at a pace far above overall inflation since 2020, which underscores that extreme weather and rising rebuilding costs, not just general price increases, are the primary drivers behind what Ontario homeowners are experiencing today.

Your Home’s Condition, Location, and Claims History

Beyond the broader market forces, there are factors specific to your own property and history that influence your home insurance costs.

Older Homes and High-Risk Features

Many Ontario homes have outdated systems like knob-and-tube or aluminum wiring, galvanized steel plumbing, and roofs older than 20 years, which are seen as high-risk by insurers. These features increase the likelihood of a claim and make your property more expensive to insure. If you’ve recently had a home inspection, flag any of these issues; it may explain a jump in your renewal premium.

Where You Live in Ontario

Location plays a significant role in determining your insurance premium. Many communities in northern Ontario, particularly rural communities, pay 30% to 80% more for their home insurance than cities around southern Ontario. Homes situated near flood-prone waterways, in areas with limited fire services, or in communities that have experienced a high concentration of recent claims may all face steeper increases.

Even within the GTA, premium levels vary considerably by postal code. Insurers use localized data, floodplain mapping, wildfire exposure, crime rates, and neighbourhood claims history to assess risk at a granular level.

Your Claims History

Maintaining a claims-free record can help keep your insurance premiums lower. Insurance companies view a history of claims as an indicator of future risk, so a single water damage claim adding $376 annually to your premium is not unusual. If your household has filed multiple claims in recent years, that history is a likely contributor to your current home insurance rates.

In Ontario, insurers can also use your credit score to help determine your risk level. A strong score may qualify you for lower rates, so it’s worth keeping that in mind when managing your overall financial health.

What Can You Do About Rising Home Insurance Costs?

While the broader forces driving up insurance costs are largely outside your control, there are meaningful steps you can take to manage what you pay. Here are some of the most effective strategies Ontario homeowners can consider right now.

Shop Around and Compare Quotes

Shopping around for insurance can lead to significant savings on premiums. Many homeowners simply renew with their current provider year after year without checking whether a better rate is available elsewhere. Consulting with different insurance brokers can help you find the best coverage options across multiple insurance companies, something a direct writer simply cannot do.

Bundle Your Home and Auto Insurance

Bundling your car insurance and home insurance policies can save you money. Most insurers offer meaningful discounts when you consolidate your home and auto insurance coverage under the same policy. It’s one of the easiest ways to reduce your overall insurance costs without sacrificing coverage.

Reassess Your Coverage Needs

Reassessing your insurance needs can help reduce your premium costs. Are you carrying coverage you no longer need? Is your home’s insured value still accurate? Adjusting your deductible or reviewing optional riders with your broker can uncover savings without leaving you under-protected.

Reduce Risk at Home

Updating older home systems, like replacing aging wiring, upgrading plumbing, installing a sump pump, or a backwater valve, can make your home less of a risk in the eyes of your insurer. Some improvements may qualify you for premium reductions. Installing monitored alarms for fire and security is another straightforward way to demonstrate lower risk and potentially lower your insurance costs.

Make Sure Your Flood Coverage Is Adequate

Given that overland flooding is the single most costly natural disaster in Canada, and that only about 55% of Canadians carry flood coverage, this is a conversation worth having with your broker. Standard home insurance policies often do not include overland flood coverage by default. Adding it may increase your premium modestly, but it protects against costs that could otherwise reach tens of thousands of dollars out of pocket.
