Winter Maintenance

Snow on pine tree

The City of Thorold provides winter maintenance services to help residents and travelers navigate their driving routes with ease.  The City performs Winter Maintenance to more than 300 lane kilometers of roads throughout the City with a fleet of dump trucks, loaders, backhoes and a grader.

Understanding how the program works

Winter Maintenance starts as soon as a storm is in the forecast.  To determine when plowing, salting and/or sanding will take place City staff consider a number of factors including:

  • Temperature
  • Future Forecasts
  • Precipitation Levels

The City is divided into several routes for both plowing and for sanding/salting.  The approximate time to complete these routes is shown below.


Sand/Salt - There are 9 routes and takes roughly 4-6 hours to complete

Snow/Plow - There are 8 routes and takes roughly 8-12 hours to complete


These times may vary for each event as they are dependent on several factors:

  • Snow depth and weight
  • Length of snow event
  • Time of day

Along each route, the main roads (primary and collectors) are addressed first as they typically handle more traffic.  Once the main roads are complete, the fleet then moves to the local roads (side streets and cul-de-sacs).

In courts and cul-de-sacs the snow plows push the snow into a pile in the middle of the paved area.  The City does not remove these piles of snow.  Please keep children from playing around these piles of snow as they are within the active roadway.


How you can help with Winter Maintenance

City Winter Maintenance crews take pride in their efforts to make the City of Thorold's roads safe.  You can help by doing a few simple things to make the area around your property safer.

  • Please shovel snow from your driveway and sidewalks onto your property.  Placing snow on the roadways or public sidewalks is a violation of the Highway Traffic Act.
  • Keep your sidewalks clear from snow and ice.  It helps to prevent slip and fall accidents and it also helps those using walkers, canes, strollers and wheelchairs.
  • Remind your children not to climb or play on snow banks as it can be dangerous, especially around active roadways.

Why does the snow plow push snow onto the end of my driveway?

The primary objective of the City of Thorold Winter Maintenance crews is to maximize the quality of snow clearing on the travelled portion of the roadway.  Snow plows do not have any other place to push the snow except to the curb or to the shoulder of the road.

Sometimes this can happen shortly after you have finished shoveling your own property.  It is understood that this can be frustrating; however, your cooperation is greatly appreciated in clearing this snow without placing it back on the roadway.

The City does not provide services to remove the snow from the bottom of your driveway.

Who do I call to report a street that has not been cleared.
It is important to remember that the first priority of the City Winter Maintenance crews is to keep the main roads clear.  It is asked that residents be patient.  The crews will get to the residential roads as soon as possible.  Roads are cleared in a priority sequence, beginning with primary roads, followed by collectors, local roads and the cul-de-sacs.

Damages to Boulevards and Roadways

It should be noted that the City of Thorold is not responsible for any damage to plants, driveway curbs or other items that have been placed on or in the boulevards.

Any damages to City owned trees, sod and pavement will be repaired in the spring by City Staff when time permits.

Parking Restrictions

Vehicles parked on the roadway prevent Winter Maintenance crews from clearing the roadway of snow in a timely and efficient manner.  When a snow plow is forced to go around a parked vehicle it leaves an embankment of snow which creates difficulty for other drivers and allows for a build up of snow to occur on the roadway.  For this reason parking on the roadway when snow clearing measures are taking place is a violation of the City of Thorold Parking and Stopping By-law (150-2012).

Typically, Parking Enforcement Officers begin their patrol shortly after the snow plows begin their route and may continue well after the plows are complete.  A vehicle found to be interfering with snow clearing measures is subject to a fine of $100.00 and may be towed at the owner's expense.

Please remember, during snow clearing events you are able to park on your apron until such time the plow has cleared your road, your vehicle must then return to the road for parking.

If parked vehicles are a problem on your street, please contact the By-Law Enforcement Division at 905-227-6613 or
