Aviva Canada turned in an underwriting loss in the third quarter of 2026. The company’s discrete Q3 combined operating ratio reached 101.5%, up from 96.8% in the same period a year earlier, according to Aviva plc’s nine-month trading update. An unusually active quarter for severe weather events across multiple provinces drove the result.
The result pulled Canada’s nine-month combined ratio to 95.9%, 0.5 percentage points worse than the prior period. That puts Canada in an awkward position within the Aviva group. It is the only geography across the company’s general insurance operations where the nine-month combined ratio deteriorated year on year,while the UK improved by 0.6 points and Ireland by 5.8 points, the latter partly reflecting the prior-year impact of Storm Éowyn.
Aviva said the Canadian claims costs were “broadly in line with our market share,” which is a measured way of saying the company absorbed its proportionate share of an expensive summer. What it does not say is that the summer was genuinely severe.
Canada’s summer 2026 severe weather generated more than CA$3.7 billion in insured losses, making it the third-costliest summer on record, according to preliminary estimates from Catastrophe Indices and Quantification Inc. (CatIQ). Prairie storms across Alberta, Saskatchewan, and Manitoba accounted for the largest portion.
The underlying picture is not a deteriorating book. Aviva Canada’s personal lines premiums were up 4% in constant currency terms in the first nine months on the back of pricing actions taken across auto and property over the past 18 months. Those actions are earning through, and the full-year combined ratio target has been framed as “approaching 94%,” which requires Q4 to deliver a substantial improvement.
Nav Dhillon, chief executive of Aviva Canada, said at the half-year stage that the company did not want to “ride a soft market” and would stay focused on underwriting discipline. That stance has been consistent, but the CAT experience in Q3 meant that even a well-disciplined book absorbed a quarter of elevated losses. Intact Financial and Definity Financial together estimated approximately $850 million in catastrophe losses for Q3 2026, net of reinsurance, driven by the same events.
The Q3 experience reinforces what Aviva has been saying about property underwriting discipline in CAT-exposed regions. British Columbia wildfires, Prairie hailstorms, and Ontario flooding all featured in a quarter that pushed the combined ratio above 100. Earned rate improvements and improved weather experience in Q4 are what Aviva needs to close the gap on the full-year target.
Canada’s commercial lines position adds a separate layer of complexity. Nine-month commercial premiums were flat year on year. It was described in the trading update as being driven by scheme wins in Aviva’s Global Corporate and Specialty unit, partly offset by competitive rating conditions. That is a different kind of pressure from the weather-related one, and both are running simultaneously.
Paul Fletcher, managing director of business and broker distribution at Aviva Canada, said at an industry briefing that the soft commercial market could last through 2027. Peter Janzen, executive vice-president and president of Intact Insurance Canada, put the soft market’s remaining life at a similar length, telling the same briefing he expected 18 to 24 more months of soft conditions. For commercial lines brokers, the competitive conditions across Canada’s P&C market in 2026 have meant real downward pressure on premiums, particularly in liability and commercial combined lines.
Aviva Canada has been clear that it will not compete on price to win business, and will continue to decline submissions where the terms do not meet its underwriting standards.
At the group level, Aviva’s performance remains strong. General insurance premiums rose 19% to £11.8 billion over nine months, the group Solvency II cover ratio reached 179%, and the company expects to meet its full-year earnings per share growth target of approximately 11%. Canada represents £3.3 billion of that premium base in sterling terms as reported by the group - a significant operation, and one where Aviva has signalled it intends to grow through brokers and partners over the medium term.
The full-year 2026 COR target for Canada of “approaching 94%” is achievable, but it requires a benign Q4 on weather. Given that Canada ranked summer 2026 as the third-costliest on record for insured losses, brokers placing CAT-exposed property risks should not assume that pricing has fully caught up with the underlying risk.
