Our Process
How we plan and deliver parking lot snow removal
Parking lot snow removal is the plowing, stacking, and de-icing of commercial parking areas, drive aisles, and fire routes, cleared to a pattern mapped before the season. Harrowgate Group performs it across the GTA and Ontario on a contracted trigger depth, with storage located to protect drainage, accessible stalls, and sightlines.
- 01 Send your inquiry, a few photos or a description of the site.
- 02 We come out, assess the site, take measurements, and confirm the scope.
- 03 We complete the parking lot snow removal on site, to the load and finish the job needs.
- 04 We install it, finish to grade, and clean up, one accountable crew, start to finish.
Local Context
A closer look at parking lot snow removal
Scope
Understanding parking lot snow removal
How we plow a commercial lot
The lot is walked and staked in the fall, the plow pattern and storage are mapped, and then every event is cleared to that same pattern by equipment matched to the surface.
Staking is not cosmetic. Curbs, islands, catch basins, hydrants, bollards, wheel stops, and soft edges are marked before they disappear, because an operator working at three in the morning in a whiteout cannot see them and a blade will find them. The plow pattern sets the direction snow travels so it ends up where it is supposed to end up in one movement instead of being pushed three times.
Equipment is matched to the area. Loaders with box pushers move volume efficiently across open lots and carry snow to the storage location rather than windrowing it across the aisle. Plow trucks handle drive aisles and travel routes. Skid steers work the curb lines, islands, tight corners, and the areas around dumpster enclosures and bollards where a full-size machine causes damage. Blades are set to the surface: on a concrete apron or a decorative paver area, the setup changes to protect the finish.
Stalls are recovered rather than abandoned. It is easy to plow the aisles and leave a windrow across the parking, and it is the most common reason a property loses capacity. We clear back to the stall line and clean up the rows once the event ends. De-icing follows clearing, at rates matched to pavement temperature, and every visit is logged.
Materials, drainage, and Ontario obligations
Commercial lots commonly dispatch at 2.5 cm or 5 cm. Sodium chloride is effective to roughly minus 10 degrees Celsius; below that magnesium or calcium chloride blends are required. Application rates are calibrated to pavement temperature rather than applied by habit.
Drainage governs where snow can be stacked. Piles placed over catch basins have nowhere to release meltwater, so it runs across the drive aisle and refreezes overnight, which turns a storage decision into an ice complaint and eventually a claim. Storage is located so meltwater drains to a basin, and away from sightlines at the exits where a pile creates a collision risk.
Accessible parking and the barrier-free route to the entrance have to be maintained under the Accessibility for Ontarians with Disabilities Act, which makes accessible stalls a priority clearing element and rules them out as storage. Fire routes have to stay passable and are cleared on every visit.
Chloride use is managed under the Code of Practice for the Environmental Management of Road Salts, applying to organizations using more than 500 tonnes a year on a five year rolling average and to those in salt vulnerable areas.
Salt damages the asset it is protecting. Chloride drives corrosion in reinforcing steel and causes scaling on concrete curbs, walks, and aprons, particularly on pours under a year old. Where new concrete is in play, product selection changes. This is the same durability problem our paving and concrete crews address the rest of the year.
What goes wrong, and how we prevent it
Lot failures are stall loss, refreeze across the aisle, pavement and curb damage, and a route that arrives too late to matter.
Stall loss. Windrows left across the parking rows and piles dumped in the nearest convenient spot cost the property capacity all winter. Clearing back to the stall line and mapping storage in the fall is what prevents it, and hauling is scheduled once the site genuinely runs out of room.
Refreeze. Piles on catch basins send meltwater across the aisle to freeze overnight, producing exactly the sheet of ice the service was bought to prevent. Storage placement is a drainage decision first.
Damage. Unstaked curbs and islands, wrong blade setup, and oversized equipment in tight areas produce gouged asphalt, sheared bollards, and broken curb edges. Staking, matched equipment, and operators who ran the same site last season prevent most of it.
Late service. An oversold route means the lot is cleared after the property needed it. Routes are sized to committed equipment.
No record. Section 6.1 of Ontario's Occupiers' Liability Act requires written notice within 60 days of a snow or ice injury, served on the occupier or on the contractor hired to clear the site. Time-stamped logs of each visit are the practical answer.

FAQ
Parking Lot Snow Removal FAQ
Where should snow be stacked in a parking lot?
Where meltwater drains to a catch basin rather than across a drive aisle, clear of sightlines at the exits, off fire routes, and never in accessible stalls. Storage is located during the fall site walk. Once the piles start costing the property stalls or creating refreeze, the snow is loaded out and hauled.
How do you avoid damaging curbs, islands, and bollards?
Everything that disappears under snow is staked before the season: curbs, islands, catch basins, hydrants, bollards, and wheel stops. Equipment is matched to the area, with skid steers on curb lines and tight corners rather than full-size machines, and blade setup is adjusted on concrete and decorative surfaces.
Do you clear the parking stalls or just the aisles?
Both. Clearing the aisles and leaving windrows across the rows is the most common reason a property loses capacity through the winter. Stalls are cleared back to the line and the rows are cleaned up once the event ends.
Why does the same spot in our lot ice every winter?
Almost always grade or drainage. Water ponds in a low spot or runs across the surface from a downspout, a pile, or an adjacent slope, then freezes. Salt manages the symptom. The permanent fix is regrading or adding drainage, which is work we price for the spring.
Does salt damage asphalt and concrete?
Chloride drives corrosion in reinforcing steel and causes surface scaling on concrete, especially on pours under a year old. Asphalt is less chemically vulnerable but suffers from the freeze-thaw cycling that follows poor drainage. Calibrated rates, pre-wetting, and alternative products on young concrete limit the damage.
What trigger depth applies to a parking lot?
Commonly 2.5 cm or 5 cm, depending on when the property has to be usable and how much traffic it carries. Fire routes and accessible stalls are cleared on every visit regardless of depth, and pedestrian surfaces normally run on a lower trigger than the parking.
What happens on a site with nowhere to stack snow?
Hauling becomes part of the seasonal scope rather than an emergency. Loading and truck cycles are planned and priced from the start, so the lot keeps its capacity through the winter instead of filling up in January and creating a problem nobody budgeted for.
What do you need to quote a lot?
A site plan or aerial and the address. Lot area, stall count, whether there is usable on-site storage, fire route and accessible stall locations, catch basin locations if known, and the hours the lot has to be usable let us price and plan it properly.
