Canadian commercial lines continue to soften, but that softening is not uniform. In commercial property, market segmentation is increasingly pronounced in 2026, says Aon’s Spring 2026 Canadian Insurance Market Update.
“Accounts with robust risk management, preferred occupancies, accurate valuations, and limited catastrophe exposure are seeing meaningful rate relief, enhanced wordings, and improved sublimits,” the report says.
“By contrast, properties with adverse loss histories, wood frame or highly combustible construction, complex industrial processes, or significant exposure to key natural perils continue to face tighter terms and elevated scrutiny relative to other segments in the market.”
Underwriters remain focused on severe convective storm, flood, wildfire, earthquake and windstorm, particularly in known Canadian hotspots, the report says. In those Cat-exposed areas, carriers are recalibrating sublimits and increasing deductibles. In some cases, insurers are also applying higher waiting periods or more restrictive terms, even while core all-risks pricing eases.
For clients, Aon says, this segmentation reinforces the value of reinvesting in physical risk improvements, data quality, and valuations now, so that their risk profile moves — or stays — on the preferred side of the market divide.
Aon notes underwriting discipline remains strong in 2026. But it’s expressed through selection, data quality and differentiation rather than across-the-board rate pressure. Insurers are placing heightened emphasis on accurate valuations to address years of construction cost and inflation lag, as well as high quality COPE (Construction, Occupancy, Protection, Exposure) data.
“Demonstrable mitigation such as wildfire defensible space, enhanced flood protections, hail and windstorm measures, robust maintenance programs and resilient building materials, has become a critical differentiator,” the report says.
The softer commercial market gives clients an opportunity to fund these upgrades, Aon says, by deliberately investing a portion of premium savings into:
- Updated valuations and improved total insured value and COPE data
- Targeted risk engineering and loss prevention projects
- Resilience measures, such as flood defences, wildfire hardening, and roof and envelope upgrades
- Stronger emergency response and business continuity planning.
Organizations can both unlock better terms today and reduce volatility at the next turn of the cycle. Escalating Cat frequency and severity, persistent inflation in repair and reconstruction costs, and geopolitical and supply chain volatility continue to create uncertainty around long-term loss costs and capital availability, Aon says.
“Even in a softer rating environment, carriers and brokers are leaning more heavily on analytics, catastrophe modelling, and scenario testing to design property programs that are sustainable across cycles.”
Overall, the Canadian commercial property insurance sector remains resilient in 2026, with strong underwriting performance and improved investment income supporting increased capacity and competitive momentum, despite elevated catastrophe losses.
As the year progresses, organizations that deliberately reinvest in their property programs, rather than simply banking short-term savings, will be best positioned, Aon’s report says. “Proactive risk management, improved data, and thoughtful program redesign enable buyers to capture current market benefits while building a more resilient, future-ready insurance and risk financing strategy.”
