Definity Financial Corporation (TSX: DFY) reported an underwriting loss of $8.8 million in the third quarter of 2026 (Q3 2026), reversing underwriting income of $113.6 million in the same period last year. Catastrophe losses of $190.0 million accounted for 12.8 percentage points of the Waterloo, Ont.-based insurer’s consolidated combined ratio, which rose to 100.6% from 89.4% in Q3 2025, according to the company’s November 5 earnings release.
The result is the first time Definity’s enlarged book has been tested by a severe catastrophe season since the insurer completed its $3.3-billion acquisition of Travelers’ Canadian property and casualty operations. Gross written premiums grew 36.2% to $1.67 billion in Q3 2026, but the premium gains were not enough to absorb the storm-driven claims.
Personal property was hit hardest. The segment posted a combined ratio of 112.1%, up from 83.6% a year ago, with catastrophe losses adding 32.6 percentage points compared to 3.6 percentage points in Q3 2025. Personal auto rose to 96.0% from 94.0%, while commercial lines came in at 96.1% versus 88.1%.

The quarter’s catastrophe costs reflected an industry-wide pattern. The Insurance Bureau of Canada (IBC) reported that insured losses from extreme weather in Canada have averaged more than $3.7 billion annually over the past decade, reflecting a substantial increase from previous decades. In 2024, insured losses exceeded $9 billion, making it the costliest year on record for severe weather-related damage in Canada.
Catastrophe Indices and Quantification Inc. (CatIQ) data showed losses concentrated in the Prairies and Ontario. A June storm system across southern Saskatchewan and Manitoba generated an estimated $923 million in insured losses, ranking third by claims count in CatIQ’s catastrophe database. Saskatchewan Government Insurance alone received claims expected to exceed $100 million from the June 9 Regina hailstorm, while Manitoba Public Insurance logged 29,195 hail-related claims from the same event.
In Ontario, storms on September 2 and 3 caused an estimated $563 million in insured damage across the southern part of the province, with Toronto taking the worst of the hail and wind. Earlier in the summer, storms across Ontario and Quebec between June 30 and July 3 produced losses of $491 million, driven largely by basement flooding in Ottawa.
Brokers placing personal property risks in the Prairies, the Greater Toronto Area, and Ottawa should expect underwriters to look more closely at valuations, deductibles, and mitigation measures heading into 2027 renewals. The 112.1% personal property combined ratio at Definity, paired with a 105.0% personal property result that Intact Financial Corporation posted in its own Q3 2026 earnings, suggests the pressure on that line extends across carriers.

Despite the underwriting loss, Definity’s top line continued to grow through its broker network. Personal lines premiums rose 36.9% and commercial lines increased 34.2%, with the broker channel accounting for the bulk of the gains. The direct channel grew 4.1% by comparison. Year to date, gross written premiums reached $4.87 billion, up 35.4%, which the company said keeps it on track for its full-year target of $6.5 billion.
“Gross written premiums increased 36.2%, driven by strong retention of the acquired renewal book and ongoing underlying growth contribution, keeping us on track to achieve our full-year gross written premium target of $6.5 billion,” said Rowan Saunders, president and CEO of Definity, in the earnings release.
The gap between broker-channel and direct-channel growth rates signals that Definity’s expansion remains broker-dependent. For intermediaries, that reliance translates into continued access to capacity and appetite from a carrier that now writes approximately $6.4 billion in pro forma gross written premiums.
Integration of the acquired book continued, with run-rate synergies reaching $56 million and contributing $14 million to Q3 2026 earnings. Philip Mather, executive vice-president and CFO of Definity Financial Corporation, said the company remains on track to capture at least one-third of its revised $125 million annual synergy target during 2026. The conversion process for all acquired product lines is now underway, which may mean system and workflow changes for brokers who previously placed business through the acquired carrier.
Net investment income rose to $79.3 million from $54.1 million a year earlier, reflecting the larger portfolio and trading into higher market yields.
Definity reported a net loss attributable to common shareholders of $32.4 million, compared to net income of $193.1 million in Q3 2025. Operating net income was $43.9 million, down from $125.2 million, for operating earnings per share of $0.36. The trailing 12-month operating return on equity was 10.3%, down from 12.5%.
Financial capacity stood at approximately $1.2 billion at quarter end, and book value per share was $34.53, up 3.3% year over year. For brokers, the capital position matters because it underpins Definity’s ability to continue writing new business and absorbing further catastrophe losses without pulling back from the market.
