The difference between named perils and all-risk insurance comes down to what causes of loss are covered and who must prove what when a claim arises. A named perils policy lists specific events that trigger coverage, such as fire, lightning, windstorm, or theft, and if the cause of your loss is not on that list, you have no claim. An all-risk policy, by contrast, covers any cause of loss unless it falls within a stated exclusion. The practical consequence is significant: under named perils coverage, you must prove your loss resulted from one of the enumerated causes, while under all-risk coverage, the insurer must prove an exclusion applies if it wants to deny your claim.
Canadian commercial property insurance has used both structures for decades, though the terminology can mislead business owners who assume "all-risk" means everything is covered. It does not. Every all-risk policy contains exclusions, and some of those exclusions are broad. Common exclusions in all-risk commercial policies include gradual deterioration, wear and tear, inherent defect, contamination, earth movement, flood, and intentional acts. The policy may also exclude specific perils through endorsements that carve out coverage for events like sewer backup or overland water unless you purchase that protection separately. Reading your policy's exclusions section is essential because that section defines the outer boundaries of your coverage just as much as the insuring agreement itself.
Named perils policies, sometimes called specified perils or basic perils coverage, protect against a finite list of causes. A typical named perils commercial property form in Alberta might cover fire, lightning, explosion, windstorm, hail, riot, civil commotion, aircraft impact, vehicle impact, smoke, vandalism, and certain water damage such as sudden escape from plumbing systems. If your building suffers damage from a cause not on the list—say, weight of ice and snow causing a roof collapse when that peril is not enumerated—you face denial. The advantage of named perils coverage is typically lower premium cost. The disadvantage is that unusual or unexpected causes of loss may fall outside your protection entirely, leaving you to absorb the expense.
Business owners often hold policies without knowing which structure applies to their coverage. The declarations page of your policy will typically indicate the coverage form, but the language varies among insurers. Phrases like "comprehensive" or "broad form" often signal all-risk coverage, while "basic form" or "specified perils" usually indicates named perils. When the declarations page is unclear, the insuring agreement section of the policy wording will state either that all risks of direct physical loss are covered except as excluded, or that loss by the following perils is covered, followed by an enumerated list. If you cannot determine which structure applies after reviewing these sections, ask your broker or insurer directly and request written confirmation.
The burden of proof difference between these two structures matters most when a claim becomes contested. In Alberta and across Canada, insurers denying all-risk claims must demonstrate that an exclusion applies. Courts have consistently held that exclusions in all-risk policies are interpreted narrowly and that ambiguity favours the insured. Under named perils coverage, the burden falls on you to establish that your loss resulted from one of the listed causes. If the origin of damage is uncertain—perhaps multiple factors contributed or the evidence is inconclusive—that uncertainty works against you in a named perils claim and against the insurer in an all-risk claim. This distinction can determine the outcome when physical evidence has been destroyed or when the cause of loss involves a chain of events with multiple contributing factors.
Many commercial property policies combine both structures within a single contract. Your building might carry all-risk coverage while outdoor signs, fences, or equipment in transit carry named perils coverage. Contents might be insured on a different basis than the structure itself. Business interruption coverage often follows the same coverage structure as the underlying property coverage, meaning if fire triggers building coverage and interrupts your operations, business interruption coverage responds, but if the interruption results from an excluded cause, both coverages fail. Reviewing each section of your policy separately is necessary because the coverage structure for one category of property does not necessarily apply to another.
Endorsements can modify either structure. An insurer might add coverage to a named perils policy by endorsement, expanding the list of covered causes. Conversely, an all-risk policy might contain endorsements that introduce additional exclusions or sub-limits for certain perils. Earthquake coverage in British Columbia, for instance, is commonly written as an endorsement with its own deductible and limit, separate from the base policy. Overland flood coverage has increasingly appeared as an optional endorsement in commercial policies since significant flooding events prompted insurers to offer the protection more widely. Each endorsement changes the scope of what is covered, and the endorsement wording controls when it conflicts with the base policy.
When reviewing your coverage or renewing your policy, consider whether the perils most likely to affect your operations fall within your protection. A business operating in a flood-prone area needs to confirm whether flood is excluded and whether endorsement coverage is available. A business with expensive outdoor equipment might need to verify whether that equipment carries the same coverage structure as building contents. Understanding the difference between named perils and all-risk coverage allows you to have an informed conversation with your broker about whether your current structure fits your risk profile or whether adjustments are warranted. The time to discover gaps is before a loss occurs, not when an adjuster explains why your claim falls outside the policy's protection.
