Best Insurance Companies for Construction in Canada | Brokers on Construction

Canadian brokers voted — here are the best construction insurers in Canada, 5-Star ranked for 2026

The anatomy of a 5-Star Construction insurer Five qualities that define every winning insurer — as voted by Canadian brokers Click any pillar to explore what brokers look for — and why it matters in 2026's market. All 6 full-submission winners offered Builder's Risk and Wrap-Up Liability. The majority extended to Environmental and Professional Liability cover.

The best construction insurance companies in Canada bring underwriting expertise that is genuinely specific to construction – not generic property and casualty capability adapted to the sector. Malfa says, “You need to have the right underwriting bench where you’re actually doing a lot of loss and risk prevention up front, and the underwriters have knowledge into that.” For a broker placing a project worth tens or hundreds of millions of dollars, this distinction is material.

Risk engineering – the proactive guidance a specialist construction insurer provides on how to reduce loss frequency and severity – was a recurring theme across broker feedback. Water damage sits at the top of the claims frequency table for construction projects, and the highest-rated firms distinguish themselves by bringing practical, project-specific guidance to the table: water shutoff maps, end-of-day valve checks, temporary heat and freeze plans, moisture management systems, and leak detection technology. “That makes a big difference outside of price,” Malfa says, “because that actually will help bring the price down and it’ll help the project run smoother.”

The second major differentiator – and arguably the most decisive – is claims capability. When comparing two otherwise similar quotes, brokers will choose the carrier with the better construction claims bench. What that means specifically is adjusters who are construction-literate: who understand Canadian Construction Documents Committee (CCDC) contracts, project schedules, and the operational consequences of delays, combined with speed to decision and clear lines of authority.

“How quickly can they arrive at a decision and what level of authority do they have before they have to escalate?” Malfa asks. “Because oftentimes, what we see are large settlements that require many layers of escalation and that slows things down completely.”

Transparency – clear timelines, regular broker updates, a practical approach to keeping projects moving – rounds out the claims picture. See how Canada’s top-rated construction insurers approach construction insurance claims handling standards in Canada in IBC’s 2025 Brokers on Construction report. Every 5-Star winner covered builders risk, course of construction, and wrap-up liability as standard – the table-stakes products any serious construction insurance company in Canada must offer.

The majority extended to environmental and pollution liability, professional liability and errors and omissions, delay in start-up, installation floater, and contractors’ equipment cover. The differentiator is how well wordings align with CCDC contract requirements and how flexible underwriters are on mid-term amendments. For context on the commercial insurance environment in which these standards apply, the Insurance Bureau of Canada commercial insurance market data provides a detailed breakdown of 2024 insured commercial losses across Canada.

Brokers consistently cited same-day decision capability on complex risks as a meaningful competitive advantage when rating specialist construction insurers in Canada. Human underwriters available by phone, portal self-serve for smaller risks, and turnaround measured in hours rather than weeks – these were the service standards that separated the best-rated firms from the field. In a soft market where technical margins are compressed, the quality of the broker relationship increasingly determines which insurance companies earn nominations.

Brokers returned repeatedly to the question of whether a construction insurance company would still be present when the market hardened. A carrier that entered the construction space during benign conditions and exited when profitability declined offered no real value to brokers building long-term client relationships. The best construction insurers in Canada have demonstrated presence through multiple market cycles – hard and soft – with consistent wordings, maintained capacity, and staff who know the sector deeply.

The five pillars above – underwriting expertise, claims capability, coverage breadth, broker accessibility, and stability – were identified through broker nominations and insurer submissions for the IBC Brokers on Construction 2026 report. They represent what Canadian brokers consistently look for when selecting the best construction insurance companies in Canada. Canada's catastrophe loss decade Annual insured losses from severe weather events (CAD billions) — why claims capability matters 2001–2010 annual average $0.7B per year 2016–2025 decade total $37B nearly 3× prior decade 2024 record total $8.5B first time over $8B in history The chart above illustrates the long-run deterioration of Canada’s catastrophe loss environment – a trend with direct implications for the cost, availability, and terms of construction insurance in Canada.

When $8.5 billion in insured losses land in a single calendar year, as they did in 2024 according to IBC and CatIQ data, the entire market tightens its scrutiny of risk quality. The result is that a record loss year reinforces rather than undermines the value of long-term, expertise-driven insurer relationships – exactly what the 2026 broker nominations reflect.

Civil construction starts 2026 +30% Only major category growing Federal infrastructure committed $115B over 5 years Hover a bar to explore — Each sector carries distinct insurance implications for brokers and their construction clients in 2026. The construction landscape that specialist insurers must navigate in 2026 looks markedly different from the market that shaped the current generation of underwriters.

Residential starts – particularly the wood frame multi-family projects that historically dominated the construction insurance book – are declining. ConstructConnect Canada projects a five percent fall in residential starts in 2026, with single-family down 11.6 percent. Commercial construction faces a far sharper correction, with starts projected to fall 45.7 percent from their 2025 high.

The counterweight is civil infrastructure. ConstructConnect projects nearly 30 percent growth in civil construction starts in 2026, driven by a federal infrastructure commitment of $115 billion over five years and the $51 billion Build Communities Strong Fund launched in 2026. For brokers whose residential contractor clients are pivoting into civil work, this creates both an opportunity and a challenge: civil risks require construction insurance companies in Canada with public works appetite and CCDC-equivalent contract knowledge – not simply extended multi-family residential programs.

Specialty Program Group (SPG) Canada has been operating in the Canadian construction insurance market for close to eight years – long enough to have navigated a hard market and now to be working through what its construction team describes as the softest cycle it has ever seen. For the managing general agency (MGA), that longevity is not incidental to its appeal to brokers placing construction risks in Canada. It is the point.

“We’re not leaving, we’re not going anywhere,” says Chris Pauli, who leads SPG Canada’s construction team. “Somebody might come in and write a bunch of business and then exit in a year when they don’t think it’s profitable anymore. We’re not in that position.”

That stability –underwritten by parent company SPG’s broader scale of more than 500 staff – translates into something brokers rely on across market cycles: consistent wordings, maintained capacity, and a claims operation that does not disappear when conditions tighten. SPG Canada has assembled approximately $80 million in capacity across more than 20 individual contracts, including multiple Delegated Underwriting Authorities (DUAs) and London binders. In a market where capacity is currently abundant, Pauli is candid that this is not the differentiator it will become.

“Capacity is abundant right now. So, it’s not the difference maker for us at the moment, but it will be again when it changes," he says. The team views its capacity position as a foundation for the next hard market rather than a current selling point.

Where SPG Canada differentiates itself among construction insurance companies in Canada is its claims capability. The firm operates Specialty Claims Canada as an in-house claims management function – a model Pauli describes as unique among MGAs in the Canadian market. “The claims team that we have in house at SPG is second to none.

There’s no other MGA that I know that has what we have,” he says. Specialty Claims Canada handles all of SPG’s claims across its portfolio, bringing construction-specific expertise to both routine losses and the major fires and structural failures that test a carrier’s true capabilities. “Those big ones are what differentiates us,” Pauli says, “where we have expertise, we have knowledge, we know who the adjuster is that should be on that one all across the country.”

In the case of a major fire claim, the response team is on site within hours. The same adjuster who handled previous large losses handles the next, reflecting a continuity of expertise that directly benefits the broker and their client. SPG Canada’s construction group numbers around 30 people, a size Pauli deliberately maintains to preserve a family-oriented culture within a large organization.

Historically a western Canadian MGA with its construction book concentrated in British Columbia (BC) and Alberta, SPG Canada is now actively expanding its civil appetite as brokers whose clients traditionally built residential frame pivot to roads, utilities, and infrastructure. “We’re seeing a lot more growth in Alberta than we are in BC,” Pauli notes, reflecting the broader market shift away from wood frame residential construction in British Columbia toward civil and infrastructure risk further east. The construction industry as a whole has been in decline and so it’s been a bit of a struggle in terms of new projects.

We’ve got a great team – about 30 people who have been consistently there over the last few years. The senior group definitely helps us through those times where it might be a little more difficult. A lot of these guys have never been through a soft market and it’s as soft as it’s ever been.

They’re steering it for us and doing a great job. The service level to the clients has got to be number one right now. I would say market-leading capacity – multiple DUAs, multiple binders through London.

It’s around $80 million in capacity that we can put down today if we needed to, over 20-odd different contracts. And the claims team that we have in house at SPG is second to none. There’s no other MGA that I know that has what we have.

They’re called Specialty Claims Canada. We’ve had our share of losses on the construction side from some of the biggest ones in the country to many of the smaller ones. But those big ones are what differentiates us.

You need some comfort when you’re paying a million dollars in premium for something. In the case of a larger type of fire claim, they’re there within hours. The adjuster is then determined by the expertise required for that specific claim scenario.

The guy that’s handled two large fires for us is going to handle the third large fire because we’ve had excellent feedback on how those first few losses were handled. And we’re always engaged with the broker on those losses – making sure people are happy with the process, the claim service, the payments, all that. It’s the only thing we have to offer after it’s been bound, essentially.

So, it’s a big part of our business. We’re primarily out west – BC and Alberta – though we’re across the country now. We made our bread and butter from condo buildings, four- and six-storey wood frames, and we’re building less and less of those right now because of the market in Canada.

So, we’re having to pivot and help brokers in another way. We’re seeing brokers that used to write four wall frames now writing civil risks because that’s what their contractors are doing. You’ve got to know that the price today might not be the price tomorrow.

You’ve got to be out there talking to people. For brokers asking which Canadian construction insurer is strongest for builders risk insurance, all 15 winners below cover it as a core line. For wrap-up liability policy Canada, every winner offers it as standard.
