Canadian property and casualty insurers saw underwriting margins narrow in the second quarter of 2026, according to S&P Global Market Intelligence, as elevated catastrophe losses combined with insurance service revenue growth of just 0.8% year over year, the fourth consecutive quarter of decelerating expansion.
The industry's gross insurance service ratio rose 1.5 percentage points to 84.3%, with insurance service expenses climbing to $14.54 billion from $14.16 billion, outpacing revenue growth. S&P described the shift as rising underwriting pressure rather than a renewed hardening of the market.
Property losses drove most of the deterioration, and the regional breakdown lines up directly with this year's storm season. Manitoba posted a 182.3% total provincial ratio and a 229.2% personal property ratio, while Saskatchewan's property ratio approached 100.5%. Both provinces bore the brunt of the June 9-10 severe storm outbreak, an event CatIQ's latest industry estimate now puts at $923 million in insured losses, up from $850 million at the 45-day mark, with Manitoba Public Insurance alone recording 29,195 hail-related claims from that single event, more than its previous single-event record. S&P attributed Saskatchewan's elevated property ratio partly to aging stormwater infrastructure and limited property-level mitigation.
The automobile sector moved in the opposite direction, with its gross insurance service ratio improving to 85.8% from 92.6% in Q1 2026 and 87.6% a year earlier, suggesting earned rate increases and claims actions are working.
S&P flagged one specific threat to that progress: President Trump's proposed doubling of tariffs on Canadian vehicles and auto parts to 50%, effective January 2027, could meaningfully raise repair and replacement costs. That risk is already visible in the data. Statistics Canada's CPI showed passenger vehicle parts, maintenance and repair costs up 2.9% between April 2025 and April 2026, a trend tied to parts crossing the Canada-US border multiple times before final assembly, with tariff cost compounding at each crossing.
This is not the first time S&P has flagged Alberta's auto market specifically as an outlier. Its Q1 2026 report on the 2025 results found the province's largest OSFI-filing insurers posted a 113.3% gross insurance service ratio in Alberta in 2025, against 87.4% elsewhere in the country, attributing the gap to the province's rate cap constraints. That same report found the broader industry's aggregate combined ratio had improved sharply to 92.4% after 2024's catastrophe losses, a recovery this quarter's 84.3% figure suggests has now partially reversed.
Intact Insurance remains Canada's largest carrier by a wide margin, with 14.9% market share and $3.38 billion in insurance revenue, and the top six carriers together account for more than half of consolidated market revenue. S&P framed that concentration as evidence that scale, distribution and capital flexibility matter more when a single quarter can swing on Prairie storm losses.
S&P also noted that only 41.9% of Canadian P&C premiums come from Canadian-owned parent companies, and pointed to Tokio Marine Holdings' interest in geographic diversification as one signal of continued foreign consolidation appetite.
That interest has already played out in public reporting. The Financial Times reported in late August that Tokio Marine had reviewed Intact Financial Corporation directly as a possible acquisition target, alongside Australia's Suncorp and Insurance Australia Group, before dropping Intact from consideration specifically because of its size - roughly $47 billion in market value - and settling on Suncorp as the frontrunner instead. That does not eliminate the broader foreign-ownership trend S&P is describing, but it does mean the specific scenario of Canada's largest insurer being acquired is not currently on the table.
For brokers, this quarter's margin compression is a regional, Prairie-driven story layered onto a national revenue slowdown, not a uniform national hardening or softening signal. Brokers with clients in Manitoba and Saskatchewan should expect continued underwriting scrutiny and firmer renewal terms given the provincial ratios reported here, while auto lines - despite real recent improvement - carry a specific downside risk tied to a US tariff decision that will not resolve before January 2027 at the earliest.
