Federal Insurance Backstop to Boost Canada’s Resilience to Earthquake Risk: Morningstar DBRS

Key Takeaways

• $52.6 bn insured loss estimate exceeds Canada’s current insurance capacity.
• Proposed backstop mirrors US TRIA, triggering after insurer loss thresholds.
• Household earthquake coverage low: 4‑7% in Québec, 50‑65% in BC.
• OSFI stress tests require 1‑in‑500‑year quake scenario compliance.

Pulse Analysis

Across the globe, insurers are grappling with a widening protection gap for natural catastrophes. Europe’s recent April 2026 proposals for a continent‑wide risk‑sharing pool illustrate a shift toward public‑private partnerships that keep private capital engaged while limiting systemic fallout. Canada mirrors that pressure: seismic hazard maps from Natural Resources Canada pinpoint British Columbia, Québec and Ontario as epicenters, and a single major quake could generate $52.6 bn in insured losses—far beyond the domestic market’s underwriting capacity. The looming threat has prompted regulators, notably OSFI, to embed one‑in‑500‑year earthquake scenarios into capital adequacy tests, underscoring the urgency of a more robust safety net.

The industry‑backed proposal, unveiled by PACICC and the Insurance Bureau of Canada, adapts the United States Terrorism Risk Insurance Act (TRIA) to the Canadian earthquake context. Under the model, insurers absorb initial losses up to a predefined deductible, after which the federal government steps in, sharing excess costs within a capped exposure limit. This layered approach preserves private‑sector incentives while providing a predictable fiscal ceiling for taxpayers. Adoption could also address the stark coverage shortfall—only 4‑7% of Québec households and 50‑65% of British Columbia homes carry earthquake endorsements—by bolstering consumer confidence in claim payouts.

For insurers, a federal backstop would smooth the tail‑risk profile that currently drives capital buffers and reinsurance demand. Credit rating agencies, including Morningstar DBRS, note that while Canadian insurers remain well‑capitalized, an unmitigated mega‑quake could erode liquidity and trigger rating downgrades. A structured public‑private mechanism would reduce the probability of such outcomes, potentially lowering reinsurance premiums and freeing capital for growth. Moreover, clearer loss‑sharing rules could stimulate broader issuance of catastrophe bonds, a market still nascent in Canada. As policymakers weigh budgetary costs against systemic stability, the backstop emerges as a pivotal lever for safeguarding the nation’s financial resilience.
