A named-perils policy covers loss caused by the perils the policy lists. An all-risk policy starts more broadly, usually covering fortuitous direct physical loss or damage unless the policy excludes it. “All risk” does not mean every loss is insured, and neither label replaces the need to read the insuring agreement, definitions, exclusions and endorsements.
The two forms start from different coverage grants
Under named-perils coverage, the insured must connect the loss to a listed cause such as fire, lightning or windstorm. The actual list varies by policy. If the applicable peril is not listed, that coverage grant does not respond.
Under an all-risk or open-perils form, the insured must first prove that the loss falls within the initial grant of coverage—for example, fortuitous direct physical loss to insured property during the policy period. The insurer then bears the burden of establishing an exclusion it relies on. If the exclusion contains an exception, the insured generally has to establish that the exception restores coverage.
That sequence, confirmed by the Supreme Court of Canada, is more precise than saying uncertainty always favours one side. The insured still has to prove the initial coverage requirements, and clear policy language is applied as written.
“All risk” still has important limits
All-risk policies contain exclusions and conditions. Depending on the wording, these may address wear and tear, inherent vice, gradual deterioration, faulty design or workmanship, contamination, flood, earth movement, cyber events, vacancy or intentional acts. Some excluded perils can be added back by endorsement, often with a separate limit or deductible.
The Supreme Court has also emphasized that an all-risk form covers risk, not certainty. Ordinary wear or inevitable deterioration is not converted into an insured accident simply because the policy uses broad language.
Named-perils coverage depends on the actual list
Terms such as “basic,” “broad” and “specified perils” are product labels, not a substitute for the contract. A named-perils form may list fire, explosion, windstorm or other causes, but there is no safe universal list for every Canadian commercial policy.
When reviewing a named-perils form, identify:
- the property and locations insured
- each listed peril and its definition
- exclusions that narrow a listed peril
- deductibles, sublimits and waiting periods
- endorsements that add or remove protection
Where several causes contributed to a loss, coverage can turn on the policy’s causation language and the evidence—not simply on which cause appears first in a narrative.
How to identify which form applies
Start with the declarations and schedule, then locate the property insuring agreement they incorporate. An all-risk form commonly uses language such as “all risks of direct physical loss or damage,” followed by exclusions. A named-perils form grants coverage for loss “caused by” specified or listed perils.
Marketing terms such as “comprehensive” may be clues, but they are not conclusive. Ask the broker or insurer to identify the exact form number and endorsements in writing if the declarations are unclear.
One policy can contain both structures
A package policy can use an all-risk form for a building and a narrower form for property in transit, outdoor property, equipment breakdown or another category. Business-interruption coverage may also require damage from a peril insured under the linked property section.
Review each coverage part separately. Finding all-risk wording in one section does not make the entire policy all-risk.
Endorsements can materially change the answer
An endorsement can add a peril, remove an exclusion, impose a sublimit or replace wording in the base form. The endorsement and policy must be read together. Where they conflict, the specific amending language usually controls to the extent of the conflict.
For renewal or placement, build the review around the business’s actual exposures rather than the label on the quote. Confirm how the policy treats water, sewer backup, flood, earthquake, equipment in transit, off-premises property, testing and any unusual operations. Record the form numbers and endorsements accepted so the final policy can be checked against the placement instructions.
The practical difference is therefore the starting coverage grant and the resulting proof sequence. Named-perils coverage requires a listed cause; all-risk coverage begins broadly but remains subject to its initial requirements, exclusions, conditions and endorsements.
