Ontario home insurance costs surge amid climate pressures

Home insurance costs in Ontario are climbing at a pace well above inflation, reflecting the mounting toll of extreme weather and rising rebuilding expenses. 

Average premiums in the province rose 7.15% in 2025 compared to last year, more than triple the inflation rate of 2.3% and above the national increase of 5.3%. Over the past decade, Ontario’s home insurance premiums have jumped 84%, far outstripping general consumer prices, which grew by 28%. A study by Canadian insurtech MyChoice analyzed thousands of quotes from January to September 2025 to compare year-over-year premiums across Ontario municipalities. The analysis controlled for homeowner profile and coverage to isolate rate movements.

The sharp increases follow a record year for insured losses in Canada. Severe weather caused $8.5 billion in insured damages in 2024, the highest on record. Events such as the Jasper wildfires, with $1.1 billion in damages, and Ontario’s summer flash floods, at nearly $940 million, added pressure to an already strained system.

Northern Ontario was hit hardest. Thunder Bay saw premiums jump 26.39%, while North Bay and Huntsville rose 22.64% and 19.72% respectively. Communities with higher wildfire exposure, including Kenora, Timmins and Sudbury, all posted above-average increases. Flood-prone cities also faced steep hikes: Pembroke rose 22.17%, Ajax 22.11% and Ottawa 14.30%.

Other parts of the province saw notable increases as well. Mid-sized cities such as Brockville (+16.77%), Burlington (+15.97%) and Belleville (+14.26%) recorded double-digit gains, alongside larger centres including London, Windsor and Mississauga.

Not every community faced such steep hikes. Several municipalities, including Gravenhurst, Innisfil and Welland, saw little change. A small number, such as Woodstock (−5.86%) and Waterloo (−5.11%), recorded declines. The uneven pattern reflects the highly localised way insurers price coverage, which can vary based on wildfire exposure, floodplain mapping, crime rates and claims history.

Several forces are driving premiums higher. Construction costs remain elevated due to supply chain pressures and higher labour expenses, raising the cost of rebuilding.

Water damage, now the most common home insurance claim in Canada, is testing aging infrastructure across Ontario. At the same time, reinsurers have raised prices after heavy global losses in 2023–24, increasing costs for primary insurers.

The implications for the market are significant. Premium increases risk making home coverage less affordable for households, particularly in high-risk areas. Insurers are tightening their pricing models and relying more heavily on granular risk data, while homeowners face growing pressure to invest in mitigation measures or shop around for competitive rates.

Without broader solutions, affordability could become a central issue for Ontario’s home insurance sector, the study suggested.
