Every January we sit down with the public data — Insurance Bureau of Canada (IBC) releases, CatIQ catastrophe tallies, Statistics Canada surveys, federal insolvency statistics, and the global breach-cost studies — and ask one question on behalf of Ontario business owners: what actually changed, and what should you do about it at your next renewal?
The 2024 answer is dramatic. Canada just recorded the most expensive year for insured catastrophe losses in its history, by a wide margin, while the commercial insurance market simultaneously loosened for well-run businesses in most lines. Both things are true at once, and understanding why is the key to buying coverage intelligently in 2025. This report walks through the numbers, line by line.
2024: the year the catastrophe curve bent
Start with the headline number. Insured losses from catastrophic weather events in Canada reached roughly $8.5 billion in 2024 according to IBC, citing CatIQ data — obliterating the previous annual record of about $6 billion (2016, the Fort McMurray wildfire year) and nearly tripling 2023's total of roughly $3.1 billion. For perspective on how fast this curve has bent: through the 1990s and early 2000s, Canada averaged around $400 million a year in insured cat losses. The past decade normalized $2 billion. 2024 quadrupled that new normal.
The damage came in a brutal summer sequence. In July, flash flooding swept Toronto and southern Ontario, and the Jasper wildfire destroyed a third of the townsite — over a billion dollars insured. In August, a hailstorm hammered Calgary with insured losses approaching $3 billion, the costliest hail event in Canadian history and the second-costliest insured event of any kind. Days later, the remnants of Hurricane Debby dropped record rainfall on Quebec, adding roughly $2.5 billion more. Four events, five weeks, most of the record.
Ontario's specific lesson from 2024 is water. The July storms flooded commercial basements, stalled fleets on flooded highways, and shut businesses for days across the GTA — the kind of event that touches commercial property, business interruption, and commercial auto claims simultaneously. Urban flooding is now Ontario's defining catastrophe peril, and insurers price like they know it.
What catastrophe math does to your property renewal
Catastrophe losses flow to business premiums through a specific mechanism: reinsurance. Insurers buy their own insurance against catastrophe years, and after the global reinsurance market repriced sharply in 2023 — property-catastrophe reinsurance costs jumped by double digits worldwide at the January 2023 renewals — Canadian property rates carried that cost through 2023 and 2024. A record 2024 cat year keeps that pressure from fully unwinding, even as the broader market softens.
Practically, expect commercial property in 2025 to remain the firm line: flood and sewer-backup deductibles rising in exposed areas, more attention to roof age and construction details, and real premium differences between buildings with and without water mitigation. The levers a business controls are the underwriting details — backwater valves, monitored water sensors, documented maintenance — and honest insurance-to-value, because rebuilding costs inflated hard over 2021–2024 and underinsured limits meet co-insurance penalties at exactly the wrong time.
One more property-market note from the public record: after years of climbing cat losses, IBC has repeatedly flagged that a meaningful share of Canadian flood risk sits effectively uninsurable in the private market — the reason Ottawa has been developing a national flood insurance program for high-risk residential properties. Commercial buyers in flood-exposed locations should read that as a signal: capacity exists, but it's priced, conditioned, and worth locking in with an insurer who understands your specific site.
The market cycle: softening, but split
Away from catastrophe-exposed property, 2024 confirmed what brokers had been seeing since late 2023: the hard market that began around 2019 — years of double-digit commercial rate increases, shrinking capacity, and underwriters saying no — has eased. Global commercial rate indices from the major brokerages showed increases decelerating through 2024 to the low single digits on average, with some segments flat or down. Canada followed the pattern. Competition returned for well-performing risks; insurers are growing again.
But 'the market' is now several markets. Liability lines for standard risks: genuinely competitive, with multiple insurers quoting where two years ago there was one. Professional liability and D&O: improved markedly from the 2020–2022 squeeze, especially for private companies with clean financials. Property: firm, for the reinsurance reasons above. Commercial auto: still rising, for reasons of its own (next section). The uniform hard market is over; a line-by-line market has replaced it.
The strategic implication for buyers is that 2025 rewards shopping in a way 2021 simply couldn't. When capacity is scarce, marketing your account changes little. When insurers are competing again, the difference between a rolled-over renewal and a properly marketed one is real money — which is precisely the work an independent brokerage exists to do.
Commercial auto and the theft crisis
Commercial auto refused to join the softening, and the public data explains why. Vehicle theft in Canada reached crisis scale: insurers paid out over $1.5 billion in theft claims in 2023 per IBC — the worst year on record and roughly triple the level of just a few years earlier — with Ontario the epicentre. The federal government convened a national summit on auto theft in 2024; port inspections and enforcement increased, and by late 2024 theft rates had begun easing off their peak, but claim costs remain far above historical norms.
For businesses running vehicles, theft is only half the story. Repair costs have inflated with vehicle technology — a bumper is now a sensor array — and commercial claims severity rose accordingly. The result: fleet and commercial auto renewals through 2024 commonly outpaced the rest of the program, and 2025 looks similar.
What works against it, per the insurers' own filings and credits: telematics programs, aftermarket immobilizers and tracking on theft-targeted models, secured overnight parking, and driver-file discipline. Fleets that can demonstrate those controls are being rated visibly better than fleets that can't — the auto market is hard, but it is not indiscriminate.
Cyber: from chaos to underwriting discipline
Cyber insurance spent 2020–2022 in crisis — ransomware losses spiked, premiums doubled, capacity fled. The 2024 story, visible in both global market reports and Canadian placement experience, is stabilization through discipline: premiums flattened and even declined for businesses with strong controls, while insurers held the line on minimum security requirements. Multi-factor authentication, tested backups, and endpoint protection stopped being premium credits and became entry tickets.
The threat itself didn't shrink. Statistics Canada's cyber security survey work has consistently found roughly one in six Canadian businesses impacted by cyber incidents, with incident response costs climbing. IBM's Cost of a Data Breach study put the average total cost of a Canadian breach above $6 million in 2024 — driven by detection, notification, lost business, and recovery across an average lifecycle measured in months. Small businesses sit below that average in absolute dollars and above it in survivability terms: a six-figure incident is existential at small scale.
Our read for 2025: this is the best cyber buying environment in five years for prepared businesses. If you were declined or priced out in 2022, re-market now — with your controls documented — and if you've never carried the coverage, the gap between premium and exposure has rarely been wider. The anatomy of a modern cyber claim — breach coach, forensics, notification, restoration — is exactly the machinery a small business cannot improvise.
The small business economy underneath
Insurance sits on top of the real economy, and 2024's real economy was hard on small business. Federal Office of the Superintendent of Bankruptcy data showed business insolvencies surging — 2023 filings rose over 40% year-over-year, and 2024 opened with the steepest quarterly spike in decades as pandemic-era CEBA loan repayment deadlines hit, before easing later in the year. The businesses that remain are operating with thinner buffers than at any point since 2020.
Thin buffers change insurance priorities. Business interruption coverage — the line that keeps revenue alive after a loss — matters more when there's no cash cushion behind it. Deductible choices deserve real thought rather than defaults. And insurance-to-value on property and equipment, after three years of replacement-cost inflation, needs verifying rather than assuming. The cheapest program that fails at claim time is the most expensive thing a fragile business can own.
The counterweight in the data: Canada still counts roughly 1.2 million employer businesses, 98% of them small, employing nearly two-thirds of the private workforce — and formation continued through the turbulence. The small business economy is stressed, not shrinking. It just has no room for uninsured surprises.
The industry behind your policy: Canada's P&C sector by the numbers
Because this is an industry report, a portrait of the industry itself. Canada's property and casualty insurance sector writes on the order of $90 billion in direct premiums a year (IBC's annual Facts publication), spread across roughly 190 private insurers — a genuinely competitive market by global standards, which is why an independent brokerage's access matters: no single insurer sees even a tenth of it. The sector employs somewhere around 130,000 Canadians across underwriting, claims, broking, and adjusting, and pays out claims measured in the tens of billions annually — property, auto, and liability combined.
Two structural facts worth knowing as a buyer. First, solvency: Canadian insurers are capital-regulated by OSFI federally (and provincial regulators for provincially-incorporated companies) against tests they hold comfortable margins above — Canadian P&C insurer failures are genuinely rare events, a handful over the past few decades. Second, the backstop behind the backstop: PACICC, the industry-funded compensation corporation, protects policyholders within limits if a member insurer ever does fail. You are not just buying a promise; you're buying a promise inside one of the more heavily supervised financial systems anywhere.
The industry is also, per its own persistent complaint, among the most heavily taxed sectors in the country — premium taxes, income taxes, and provincial levies flow from your premium to governments in the billions each year. It's part of why the premium dollar divides the way it does, which deserves its own section.
Where your premium dollar actually goes
IBC publishes the breakdown most buyers never see: of each premium dollar, the majority — commonly 55 to 65 cents across the cycle — goes straight back out as claims and the cost of adjusting them. Operating expenses, including broker commissions and the machinery of underwriting and service, take roughly another 20 to 25 cents. Taxes and levies claim a meaningful slice. What's left as underwriting margin is thin and cycle-dependent — in bad catastrophe years, negative — which is why insurers historically lean on investment income earned on premiums held between collection and claim.
The industry's scorecard for all this is the combined ratio: claims plus expenses as a percentage of premiums, where under 100 means underwriting profit. The Canadian P&C industry's combined ratio swings with the catastrophe curve — comfortable in benign years, pressured hard in years like 2024 — and that swing is the honest explanation for the market cycle this report keeps referencing: sustained ratios near or above 100 harden markets; strong ones invite competition back in.
Why this matters to an Ontario business owner: premium isn't arbitrary. It's the visible end of a loss-cost machine, and the parts you can influence — your claims record, your documented controls, your risk's presentation — are exactly the parts a marketed renewal puts to work.
The costliest insured events in Canadian history — and what the list says
The all-time table, in rounded public figures, now reads roughly: the 2016 Fort McMurray wildfire (about $4 billion insured at the time, still the costliest single event); August 2024's Calgary hailstorm (approaching $3 billion); the 1998 Quebec–Ontario ice storm (well over $1 billion in 1998 dollars — multiples of that today); the 2013 southern Alberta floods (about $1.7 billion); the July 2013 Toronto rainstorm (about $1 billion); the May 2022 Ontario–Quebec derecho (about $1 billion); 2024's Jasper wildfire (over $1 billion); Hurricane Fiona in 2022 (around $800 million — Atlantic Canada's costliest event); the 2011 Slave Lake wildfire (roughly $700 million); and the 2021 British Columbia atmospheric-river floods (about $675 million).
Read the list twice and two patterns fall out. Every major peril is represented — wildfire, hail, flood, ice, wind — so 'catastrophe' in Canada is not one risk but a portfolio of them. And the recency skew is stark: the large majority of the entries land in the last decade, which is the entire reinsurance repricing story of this report told as a list of place names.
The Ontario-specific note: three of the entries — the ice storm, the 2013 Toronto rainstorm, and the 2022 derecho — hit this province directly, and 2024 added the July GTA flooding. For commercial property and business interruption buyers here, catastrophe exposure stopped being a Prairie abstraction years ago.
Who regulates all this — a buyer's field guide
The supervision stack, briefly, because it shapes what you're buying. OSFI oversees the solvency of federally incorporated insurers — the capital tests behind the claims-paying promise. In Ontario, FSRA regulates market conduct and, for auto insurance, the rates themselves (commercial auto filings included, which is part of why that line moves the way it does). Brokers are separately licensed and regulated through RIBO in Ontario — the professional-standards layer sitting between you and the market. And PACICC, mentioned above, backstops policyholders against the rare insurer failure.
None of this is trivia at claim time. Regulated conduct standards are why claim-handling timelines and fair-treatment obligations have teeth, and the complaint and escalation machinery exists all the way up to ombudservices when a file genuinely stalls. The system's design assumption is the same as this report's: an informed buyer, using the machinery, gets materially better outcomes than a passive one.
Line by line: our 2025 outlook
General liability: flat to modest increases for clean risks; genuinely marketable. Property: firm, with water/cat details driving individual outcomes — mitigation documentation pays. Auto and fleet: continued increases, moderating where theft controls and telematics are in place. Cyber: flat to down for controlled risks; requirements non-negotiable. Professional liability and D&O: competitive for standard risks, with private-company D&O notably more available than two years ago. Specialty and hard-to-place classes: capacity exists but relationships and presentation decide access.
Two watch-items for the year. First, weather: another record or near-record cat season would re-firm property quickly; the reinsurance market is watching Canadian hail and flood the way it watches US hurricanes. Second, the economy: if insolvency stress persists, expect underwriters to keep scrutinizing financial condition on larger risks — one more reason clean, current financials belong in your renewal submission.
What Ontario businesses should actually do
First, market your renewal — this is the year shopping works again. Give your broker sixty days runway, current financials, and your loss runs; make insurers compete for the account. Second, fix insurance-to-value: rebuild costs, equipment replacement, and interruption values have all inflated past 2021-era limits. Third, document your controls — water mitigation, theft prevention, cyber hygiene — because in a split market, evidence is the difference between the good rate and the average one.
Fourth, close the two gaps this data says matter most: cyber coverage if you don't carry it, and realistic indemnity periods if you do carry interruption. Fifth, if you were declined for anything in the hard market — cyber, D&O, a tough property — try again. The market that said no in 2022 is saying yes, with conditions, in 2025.
Sources and method
Figures in this report are drawn from public sources: Insurance Bureau of Canada releases and its annual Facts of the Property and Casualty Insurance Industry in Canada; CatIQ catastrophe loss summaries; Statistics Canada business and cyber security survey data; the federal Office of the Superintendent of Bankruptcy insolvency statistics; IBM's Cost of a Data Breach study; and published global market indices from major reinsurance and brokerage houses. Numbers are rounded and, where sources update retroactively, the most recent public figure is used. None of this constitutes advice on a specific risk — that's what the conversation is for.
If any number here changed how you think about your own program, that's the report doing its job. Talk to an advisor or start a marketed renewal — sixty days before your expiry is the sweet spot, and 2025 is a year worth shopping.
