Every business that lets customers, delivery drivers, or the public onto its property takes on a legal duty most owners never read about until something goes wrong. Occupiers' liability insurance for a business is the coverage that sits behind that duty, and it becomes especially relevant once snow and ice turn a parking lot or a front step into the most common source of a winter claim.
This article looks at what occupiers' liability actually means, who counts as an occupier under Canadian law, and how a typical commercial insurance program is designed to respond when someone is hurt on a business's premises.
What is occupiers' liability?
Occupiers' liability is the legal duty owed by anyone who controls a property to take reasonable care that people entering it are reasonably safe, covering both the physical condition of the premises and the activities carried out there. Every Canadian province has its own occupiers' liability legislation, such as Ontario's Occupiers' Liability Act and Alberta's equivalent statute, and while the exact wording differs, the core idea is consistent: control over a property comes with a responsibility for the people who use it.
For a business, this duty is not optional and does not depend on whether the business owns the building. A tenant running a shop, a restaurant leasing space in a strip mall, or a contractor with a job site trailer can all be occupiers, alongside the property's actual owner, each owing a version of the same duty.
Who is considered an occupier?
Provincial legislation generally defines an occupier as a person in physical possession of a property, or a person who has responsibility for and control over its condition, the activities conducted on it, and who is permitted to enter. That definition is broad on purpose, and more than one party can hold occupier status over the same property at the same time.
A common example is a commercial landlord and a retail tenant sharing responsibility for the same storefront. The landlord may be the occupier of the parking lot and common areas, while the tenant is the occupier of the leased unit itself, and a lease agreement often spells out which party is responsible for which area, including snow clearing. A business that assumes a landlord's insurance automatically covers the tenant's own exposure can be left with a gap that only a licensed broker reviewing the specific lease and policies can catch.
How winter weather raises the stakes
Snow and ice do not change the underlying legal duty, but they change how often it gets tested. Slip and fall incidents tied to snow and ice are among the most common sources of a winter liability claim against a Canadian business, and courts weigh a business's inspection routine and snow-clearing records closely when a claim is reviewed.
Ontario's Occupiers' Liability Act was amended by Bill 118, which received Royal Assent in December 2020 and took effect January 29, 2021, to shorten the notice period for a snow or ice injury claim to 60 days from the date of the incident, down from a much longer limitation period. According to the Legislative Assembly of Ontario, the amendment requires a written notice stating the date, time, and location of the incident, and it applies to an occupier and to any independent contractor the occupier hires to clear snow or ice. Alberta's occupiers' liability statute does not carry the same shortened notice period, which is one reason a business operating in more than one province should not assume the same rules apply everywhere.
Insurers have also seen the cost side of this trend. Commercial liability claims in Canada, a category that includes slip and fall incidents, have been reported by industry sources as rising sharply over recent years, which is part of why insurers increasingly ask about a business's winter maintenance practices at renewal.
How business insurance typically fits in
A business's occupiers' liability exposure is usually addressed within its broader liability program rather than through a standalone policy. A commercial general liability policy is generally designed to help address a third-party bodily injury or property damage claim, including one arising from a slip and fall tied to snow or ice on the business's premises, subject to the policy's specific wording, limits, and any exclusions that apply.
A business that hires a contractor to plow or salt its lot may also be asked to confirm the contractor carries its own liability coverage, sometimes with the business named as an additional insured, so that a claim tied to the contractor's work may have more than one policy available to respond. None of this replaces good documentation: insurers and courts alike tend to look favourably on a business that can show a consistent, recorded snow-clearing schedule. Coverage details vary by insurer and policy, and only the wording of an actual policy and a licensed broker can confirm what applies to a specific business.
Benefits of understanding occupiers' liability
Knowing how occupiers' liability works before winter arrives gives a business owner a clearer sense of where its exposure actually sits, rather than assuming a generic liability policy automatically handles every scenario. It also makes conversations with a landlord, a property manager, or a snow-removal contractor more productive, since a business that understands who is legally the occupier of a given area can ask sharper questions about who is responsible for clearing it.
That clarity also helps when it is time to review limits. A business that has thought through its occupier status can bring a more specific set of questions to a broker about whether its current liability limits and any additional insured arrangements still match how the property is actually used.
Where you'll come across occupiers' liability
Occupiers' liability tends to surface at a few predictable points in a business's year. It comes up when a business first signs a commercial lease and negotiates who is responsible for snow and ice clearing in shared areas. It resurfaces every fall, when a business reviews its business insurance in Canada ahead of the first snowfall and confirms its winter maintenance plan with a broker.
It also appears after an incident, when a business works through what happened with its broker and, if needed, a lawyer, or when a commercial property insurance renewal prompts a broader look at how the business's overall risk picture has changed. Businesses that lease space from a landlord who handles snow removal may see occupiers' liability referenced directly in the lease's insurance requirements, alongside the additional insured language many commercial leases already require.
Talk to a licensed broker about occupiers' liability
Occupiers' liability rules vary by province, and how they interact with a specific business's lease, contracts, and insurance program is not something a general article can map out for an individual situation. A licensed broker can review a business's premises, its snow-clearing arrangements, and its current liability limits, and help line up a commercial insurance quote that reflects how the property is actually occupied and used.
Coverage details vary by insurer and by policy, and only the wording of an actual policy and a licensed broker can confirm what applies to a specific situation.
