Snow contracting looks like a plowing business. Legally, it's a liability business that happens to own plows. The moment an Ontario contractor signs a commercial snow contract, they typically absorb the property owner's slip-and-fall exposure through indemnity clauses — and slip claims arrive months after the storm, long after anyone remembers the morning in question.
That structure isn't a reason to avoid the work; winter contracts anchor many landscaping businesses through the off-season. It is a reason to read what you're signing, insure it properly, and run the documentation habits that win claims.
How the risk transfer works
Commercial snow contracts almost universally contain hold-harmless and indemnification language: if someone slips in the parking lot, the contractor defends and indemnifies the property owner. Many go further, requiring the owner be named as additional insured on the contractor's CGL policy — meaning your insurance responds for their exposure arising from your work.
Understand what that does to your insurance economics. You're not pricing plowing; you're pricing plowing plus the premises liability of every property on your route. Underwriters rate snow operations accordingly, which is why 'we just plow a few lots' can move a landscaping premium more than the revenue seems to justify — and why undeclared snow work is one of the classic coverage gaps in the trade. If snow is in your winter, it must be on your policy.
Ontario's notice window helps — documentation wins
Ontario law gives snow contractors and property owners a meaningful protection: for injuries from snow or ice, claimants generally must serve written notice within 60 days. It screens out stale claims — but the claims that arrive on time are decided on evidence, and the contractor's evidence is their logs.
The winning file looks like this: contract showing the service level agreed; GPS or time-stamped records of every visit; salt/de-icer application records; weather conditions noted; photos where conditions were unusual. Contractors who keep that file resolve claims quickly and cheaply. Contractors who rely on memory fund long fights. The log discipline costs minutes per site and is the highest-return risk management in the industry.
Contract terms worth negotiating
Not all snow contracts allocate risk the same way. Watch the trigger definition — are you obligated at 2 cm or 5 cm, and who decides when conditions warrant salting? Per-push versus seasonal pricing changes your incentives and your documentation needs. Beware clauses making you responsible for conditions between visits regardless of weather, and clauses requiring 'bare pavement' — a standard Ontario freeze-thaw cycles make unpromisable.
Where you can, negotiate language tying your responsibility to the agreed service schedule, and keep the owner responsible for hazards you weren't contracted to treat. We review these clauses alongside snow removal coverage placements constantly — the contract and the policy have to tell the same story.
Insuring the season properly
The core is CGL rated for snow and ice operations, at limits your contracts demand — $2 million minimum, $5 million for many commercial and municipal clients. Around it: commercial auto for trucks with plows and salters declared, equipment coverage for the attachments themselves, and contractual liability wording that matches the indemnities you sign.
Certificate logistics matter too. Winter clients want certificates before the first flake, usually naming them as additional insured. Get your route list to your broker in the fall and the paperwork clears before contracts start — not during the first storm.
Pricing snow work: building the liability into the bid
Contractors who lose money on snow usually lost it at bid time, by pricing the plowing and forgetting they were also selling insurance-backed risk assumption. The professional bid builds in: the insurance premium delta for declared snow operations (get the number from your broker before the season, not after), the documentation time — GPS logs, salt records, site photos — that defensible service requires, and a margin that reflects the indemnity you're signing. A contract that transfers a property owner's slip-and-fall exposure to you at plowing-only prices is a contract that pays you to hold someone else's risk for free.
Salt and service-level clauses deserve line-item attention. 'Zero tolerance' and 'bare pavement' language sounds like diligence but functions as strict liability in a freeze-thaw climate — price it accordingly or negotiate it to a monitoring-based standard you can actually meet. Per-event versus seasonal pricing shifts weather risk between you and the client; know which side of that bet your cash flow can hold through a heavy winter.
And cap your route to your capacity honestly. Every site added past what your equipment and crew can service within the contracted response time isn't revenue — it's a documented service-level breach waiting for its slip claim. The best operators we insure bid fewer sites at better margins and sleep through storms their overextended competitors spend in court, eventually.
A claim walkthrough: the March slip, the July letter
How these files actually unfold: a woman falls in a plaza parking lot on a March morning, breaking a wrist. Nothing is said at the scene. In July, the property manager receives a lawyer's letter; within weeks, the contractor is added — the contract's indemnity clause doing exactly what it was written to do. First question from every insurer on the file: what do the records show for the seventy-two hours before the fall?
In the version where the contractor kept GPS logs and salt records, the file shows two plow visits and a salting the evening prior, consistent with the contract's trigger and the weather data. The claim resolves within policy limits, efficiently — largely on the strength of paper. In the version without records, the same facts become a credibility contest years after the morning in question, defence costs multiply, and settlement value rises with the uncertainty. Identical service, radically different outcomes, separated only by documentation discipline.
Ontario's 60-day notice requirement for snow-and-ice claims screens some late claims out — but letters that arrive inside the window still take a year or more to resolve, and your logs are the only witness that never forgets. Keep them like invoices: because in this trade, they are.
Subcontracting and route sales: the liability follows the contract
Two structures deserve their own caution flags because they quietly rearrange who holds the risk. First, subcontracting: established contractors routinely sub out overflow routes in heavy winters, and the paper matters enormously — if your subcontractor plows a site under your contract, the client's claim comes to you, and your protection is the sub's insurance plus your own. That means collecting the sub's certificate (with limits matching yours and, ideally, you named as additional insured) before their first push, and written subcontract terms mirroring the indemnities you gave the client downward. A sub with a plow and no policy is your exposure wearing their truck.
Second, buying or selling routes mid-season — common in a trade where operators retire, burn out, or expand opportunistically. The insurance question is continuity: claims from a slip in January will arrive months later, after the route changed hands, and the contract governing that site on the day of the fall decides whose policy answers. Route-sale agreements should state explicitly who carries responsibility for pre-sale service dates, and both parties' insurers should know the transaction happened. The alternative — two contractors and two insurers each pointing at the other over a July claim letter — serves nobody except the plaintiff's counsel.
The unifying rule: in snow work, liability travels with contracts, not with trucks. Every time the contract structure changes — a sub added, a route sold, a client's property manager replaced with new terms — the insurance file needs to change with it, same week. It's five minutes of admin per change, and it's the difference between a clean claim and an ownership dispute.
Residential routes: smaller sites, same discipline
Residential driveway routes feel lower-stakes than commercial lots, and mostly are — but the same legal structure applies at smaller scale, and two residential-specific wrinkles deserve attention. First, the sidewalk question: many municipalities place public-sidewalk clearing duties on the abutting homeowner, and your contract language decides whether you've assumed that duty for them. A pedestrian's fall on the public sidewalk in front of a client's home tests exactly that clause. Second, property damage frequency: lawn edges, interlock, garage doors, and parked cars absorb the trade's most common small claims, and a season of $800 sod repairs erodes margins as surely as one large claim.
The residential playbook: contracts (yes, even one-pagers) that define the cleared area and trigger, dash-cam or phone photos of pre-existing damage on first service, marker stakes installed in November, and the same visit logging the commercial side uses — GPS breadcrumbs cover a hundred driveways as easily as ten lots. Priced honestly and documented lightly, residential routes are excellent business; treated as handshake work, they're a hundred small liabilities with snowbanks on top.
The bottom line
Snow work pays because it carries risk the property owner doesn't want. Price that risk into your bids, insure it explicitly, log every visit, and the winter book becomes what it should be: dependable revenue with a defensible file behind it.
