Canada's Burning Bill: Actuaries Redraw Wildfire Insurance Map

OTTAWA, Ontario – February 26, 2026 – As Canada grapples with the escalating financial fallout of longer and more destructive wildfire seasons, the nation's risk experts are rolling out a new playbook for the insurance industry. The Canadian Institute of Actuaries (CIA) has released a comprehensive document designed to help property and casualty (P&C) insurers navigate the increasingly volatile and costly threat of wildfires.

The move comes as the country reels from unprecedented events. The 2023 wildfire season was the most destructive on record, charring an estimated 18 million hectares and contributing to over $3.1 billion in insured damages from severe weather. The threat has become persistent, with dozens of "zombie" fires from that season smouldering through the winter to reignite in early 2024, underscoring a new year-round reality for risk managers.

Developed by the CIA’s Property & Casualty Practice Committee and climate risk experts, Wildfire Risk Considerations for P&C Insurance Pricing and Underwriting provides a framework for insurers to strengthen their analytical methods. The goal is to enhance financial stability and ensure regulatory compliance in an era of accelerating climate change.

“Wildfire risk is no longer a remote or episodic concern for insurers. It is a growing and systemic challenge that requires a proactive approach,” says Shayan Sen, FCIA, Chair of the committee that developed the resource. “This resource is intended to help actuaries and insurance professionals strengthen their approaches to pricing and underwriting as wildfire risk continues to evolve.”

Redrawing the Risk Map: A New Playbook for Insurers

The new guidelines from the Canadian Institute of Actuaries offer a technical deep-dive into the complex variables of modern wildfire risk. The document provides crucial information on hazard fundamentals, including ignition sources, fuel types, weather patterns like El Niño, and topography. More importantly, it outlines sophisticated approaches for quantifying this risk, moving beyond historical data to incorporate forward-looking models using tools like average annual loss (AAL) and probable maximum loss (PML) analysis.

This guidance arrives at a critical juncture, as insurers are already scrambling to adapt. The industry has seen wildfire-related claims surge by over 300% in the last five years alone. In response, some firms are leveraging cutting-edge technology to get ahead of the flames. Swiss Re, for example, has partnered with Alphabet's Bellwether project to integrate 600 layers of geographic data and 20 years of historical patterns to forecast wildfire risk with granular accuracy up to five years in advance.

The CIA's framework aims to standardize and bolster these efforts across the industry, providing a common language and methodology. This is crucial for meeting the stringent expectations of federal and provincial regulators. The Office of the Superintendent of Financial Institutions (OSFI) has already implemented its Guideline B-15, which mandates that federally regulated financial institutions, including insurers, improve their climate risk management, governance, and disclosures. OSFI is also collecting standardized data on physical risks like wildfires to better assess aggregate exposures across the financial system.

By providing a robust methodology for assessing and pricing wildfire risk, the CIA’s document directly supports insurers in fulfilling these regulatory obligations, helping them build more resilient business models and maintain solvency in the face of potentially catastrophic loss scenarios.

The Homeowner's Bottom Line: Premiums, Availability, and Resilience

For Canadian homeowners, the abstract concepts of actuarial science are translating into concrete and often painful financial realities. As insurers refine their risk models, the cost of property insurance is skyrocketing in wildfire-prone regions, with premium hikes far outpacing increases in home values.

In Kamloops, B.C., average annual premiums nearly doubled between 2023 and 2025. In Medicine Hat, Alberta, insurance costs now represent a staggering 19% of a typical mortgage payment, making it one of the country's least affordable markets for home insurance. These dramatic increases reflect the new reality that insurers are pricing for, and they raise urgent questions about long-term affordability and availability.

Industry experts warn that Canada could begin to see a crisis similar to those in high-risk U.S. states like California, where some insurers have withdrawn coverage entirely. The pressure is already visible; Aviva Canada recently pulled out of Alberta's direct home and auto insurance market, citing a combination of regulatory and climate-related pressures. During active wildfire threats, most companies also place temporary moratoriums on selling new policies in affected areas, a practice that could become more frequent.

However, the new focus on risk quantification is also driving a push toward proactive mitigation. The CIA guidelines implicitly encourage a system where preparedness is rewarded. Several major insurers, including Intact and Aviva Canada, have partnered with Wildfire Defense Systems (WDS) to provide at-risk policyholders in Alberta and B.C. with on-the-ground protection services, such as setting up sprinklers and applying fire-blocking gels. Others, like Co-operators and BCAA Insurance, offer direct premium discounts to homeowners who complete FireSmart™ home assessments, creating a clear financial incentive for individual action.

Beyond the Balance Sheet: A Call for Collaborative Action

The CIA's guidance is a critical tool for the insurance industry, but it also highlights a broader truth: insuring against disaster is not the same as preventing it. The document itself points to the need for deeper collaboration between insurers, governments, and regulators to foster a more resilient society.

This call to action is echoed in federal initiatives. The national Wildfire Resilient Futures Initiative (WRFI) is a $285 million investment aimed at accelerating technological innovation and establishing a Centre of Excellence for wildfire science. Similarly, the National Adaptation Strategy, launched in 2023, aims to improve climate preparedness in housing and infrastructure. However, critics have noted that progress on implementation has been slow, lacking a clear economic framework to guide investment where it is needed most.

The stakes extend beyond insurance policies. Lenders are increasingly concerned about their exposure, as a lack of adequate property insurance for borrowers in high-risk zones directly threatens the value of their collateral and increases the risk of credit losses. The stability of entire communities and regional economies is intertwined with the ability to manage and mitigate this growing threat.

Ultimately, the new actuarial guidelines provide the financial sector with a clearer lens through which to view the fire-scorched landscapes of Canada's future. While this will undoubtedly lead to more accurate pricing and more stable insurance portfolios, it also sends an unmistakable signal that the risk itself must be tackled at its source through a unified national effort combining scientific research, public policy, community engagement, and individual responsibility.
