A federal flood insurance backstop promised since 2019, funded at $450 million and targeted for an April 2026 launch, still has no delivery date.
With no public mechanism in place, the job of explaining who is and is not covered for overland flood and sewer backup, and what to do about it, has fallen almost entirely to the broker desk, a dynamic now visible in a claims dispute playing out in St. Catharines, Ont.
St. Catharines declared a state of emergency in late July after three storms dropped nearly 400mm of rain on the city inside a single week, according to the city's own flood recovery updates.
The Insurance Bureau of Canada (IBC) says the resulting claims backlog reflects a capacity problem across the industry, not an isolated incident.
"Not only are the insurance adjusters inundated with all of these claims, restoration companies, in turn, are inundated with all of this too," said Anne Marie Thomas, IBC's consumer and industry relations director.
Underneath that operational strain sits a coverage structure that rarely gets scrutinized until a claim is already filed, which is precisely the point at which a broker's earlier advice, or lack of it, becomes material.
Sewer backup and overland flood protection remain optional endorsements in Canada rather than standard inclusions.
"What a lot of people do not realize is that not all policies include coverage caused by sewer backup or overland flood," Thomas said. "If you didn't buy it, you could find yourself without any coverage at all."
IBC's own data shows the access side of that problem has largely been solved at the product level. As of July 2026, the bureau reports that 94% of Canadian homes can technically buy overland flood insurance, yet external water damage still accounted for close to a quarter of all home insurance claims last year, a gap between what's sold and what's actually held that sits squarely in the advice, not the underwriting.
Roughly 850,000 homes remain ineligible for overland flood cover under current market conditions, a figure that has not moved much even as headline access has climbed. Until a federal mechanism exists, that residual exposure sits with private carriers, provincial disaster assistance programs, and the households themselves.
Ottawa's design work has stalled repeatedly, and that leaves no near-term relief on the horizon. Rachel Barry, IBC's director of federal affairs, said in June that the federal government has not committed to a date.
"There's no timeline that I can share right now from government," Barry said, adding that discussions have centred on how a federal backstop would function alongside coverage already sold by private insurers.
Ottawa is trying to balance affordability for high-risk households against the risk of an open-ended taxpayer subsidy for properties that flood repeatedly, while also getting provinces and municipalities to align land-use planning and building codes with whatever backstop eventually takes shape, a timeline measured in years rather than the next renewal cycle.
That uncertainty was underscored further in April, when the federal emergency management minister declined to promise near-term delivery, calling the file "an incredibly complicated discussion."
IBC has proposed a federal reinsurance entity structured through a Canada Mortgage and Housing Corporation subsidiary, intended to extend affordable overland flood coverage to the roughly 1.5 million highest-risk households currently priced out of the private market.
Until that mechanism exists, brokers in flood-exposed territories are the ones fielding the conversation about why a property cannot be placed, or can only be placed with a capped limit or a steep deductible.
Some carriers have moved to narrow that placement gap on their own terms. Co-operators, for one, has built its Comprehensive Water product into the only flood policy in the country available across all risk levels, including storm surge, reaching an estimated 745,000 households as of mid-2026.
That product remains the exception rather than the market norm, which means most brokers working high-risk postal codes are still managing clients through capped, expensive, or declined options rather than a straightforward sale.
David Mayer, insurance and underwriting director at Rates.ca, said home insurance pricing works differently from auto, with premiums set against location-based risk factors including flood exposure rather than an individual's claims record.
Home insurance premiums nationally have climbed as much as 45% over the past six years, according to Rates.ca figures, while reinsurance costs for Canadian property books rose 25% to 30% during the 2023 renewal cycle and by as much as 50% to 70% for books with recent losses, per TD Economics estimates, pressure that ultimately surfaces in the renewal quote a broker has to defend to a client.
Repeated regional loss events, Mayer said, feed directly into how that local pricing gets set. "But again, it doesn't necessarily mean that's going to be the case," he said, referring to any single storm cluster.
None of the above changes what happens after a loss occurs. IBC still advises documenting damage immediately rather than waiting for a restoration crew, and warns that a client who hires a contractor ahead of an adjuster's assessment carries the financial risk if coverage is later denied, a scenario a broker is often the first call for.
Unresolved claims can be escalated internally to an insurer's ombudsperson, and from there to the independent General Insurance OmbudService, a process brokers frequently end up walking clients through in the absence of a responsive adjuster.
Until a federal backstop is designed, funded, and running, the advisory and liability weight of Canada's flood insurance gap continues to sit with the broker channel rather than with any government mechanism, a position events like St. Catharines make difficult to ignore at the next round of renewals.
