Commercial Snow Removal Contracts: What to Look For

Snow removal contracts are one of those agreements that most property managers review once during onboarding and then forget about until something goes wrong. In Calgary, where a single storm event can bring 30 centimetres of snow, the difference between a well-written contract and a poorly written one often comes down to a liability claim, a board complaint, or a vendor that goes dark during the city's worst weather.

Here's what to look for before signing.

Trigger depth: this clause defines everything

The most important term in a snow removal contract is the trigger depth — the accumulation at which your vendor is contractually obligated to dispatch. Common thresholds are 5 cm, 7.5 cm, and 10 cm.

A lower trigger depth means more frequent service and higher costs. A higher threshold reduces cost but means more snow on the ground before anyone shows up. For commercial properties with high foot traffic — retail plazas, office buildings, healthcare facilities — 5 cm is a reasonable threshold. For light commercial or residential strata with lower traffic volume, 7.5 cm is typical.

What to watch for: Some contracts state trigger depth ambiguously ("significant accumulation" or "as needed"). These give the vendor discretion that doesn't protect your property. Insist on a specific numeric threshold.

Response time guarantee

Once the trigger is hit, how quickly does your vendor dispatch? This is separate from when crews arrive on your specific property — that depends on route position. But you should know the vendor's committed response time from trigger to dispatch, and ideally, their contracted arrival window for your property specifically.

In Calgary's busiest storm events, response time guarantees are what separate vendors who show up at 6 AM and those who show up at noon. Both technically "showed up," but only one protected your property.

Scope: exactly which areas are covered

Your contract should specify — with detail — which areas are covered and which are not. Common scope items:

• •Main vehicle lanes and parking lots
• •Fire routes and emergency access paths (often legally required to be cleared first)
• •Sidewalks adjacent to the property
• •Pedestrian walkways and paths within the property
• •Building entry points and vestibules
• •Accessible parking spaces and curb cuts

Areas that are often left ambiguous: loading dock approaches, rear parking areas, maintenance access roads, and private residential balconies in strata properties. If it isn't specified, assume it isn't included.

Salting and sanding: included or billed separately?

De-icing is a separate cost centre for most vendors. Ice management (salting and sanding) is often billed separately from plowing — either per application or on a seasonal basis. Before signing, confirm:

• •Is ice management included in your seasonal rate, or billed per application?
• •What is the unit price per application if billed separately?
• •What product is used (rock salt, calcium chloride, sand-salt mix)?
• •Is re-icing between storms included?

Ice management costs can match or exceed plowing costs in a Calgary winter with frequent freeze-thaw cycles. Know what you're budgeting before the season.

Vendor documentation: what your board needs to confirm

Before signing with any snow removal vendor, confirm they can provide:

• •Proof of coverage and current documentation upon request
• •WCB registration confirmation — verifies the vendor operates compliantly
• •A clear escalation and contact protocol for storm events

What to watch for: Vendors who can't provide documentation, or whose paperwork expires mid-season. Verify annually, not just at onboarding.

Seasonal vs. per-event pricing

Seasonal (flat-rate): You pay one fixed price for the entire winter regardless of how many storms occur. Good for budgeting, higher cost in light-snow years, excellent value in heavy years. Most preferred by condo boards and property managers.

Per-event: Billed each time the vendor dispatches. Lower base cost, but unpredictable — a heavy winter can dramatically exceed budget.

Hybrid: Flat rate up to a specified number of events or hours, then billed per event beyond. Becoming more common as vendors hedge against extreme weather years.

For most Calgary commercial properties, seasonal contracts are the right call. They align your vendor's incentive (efficient operations) with your interest (consistent coverage) and make budget forecasting reliable.

Documentation and reporting

Professional snow removal vendors provide service documentation after each dispatch: timestamp in, timestamp out, areas serviced, product applied (if applicable), and conditions on arrival. This documentation protects you in liability situations and confirms the vendor is performing as contracted.

If your current vendor doesn't provide service reports, that's a gap worth addressing before renewing.
