Winter maintenance

Roads Services is responsible for the City’s snow and ice control program. It is committed to helping make Ottawa’s roads, sidewalks and winter cycling network safe and passable for vehicles, pedestrians and cyclists. An effective winter maintenance program is essential to allow the City to function under normal winter weather conditions.

Between November 15 and April 1, the City may declare a Winter Weather Parking Ban for inclement weather including freezing rain or when Environment Canada forecasts 7 cm or more of snow in the Ottawa area. This includes any forecast for a range of snow more than 7 cm, such as 5 to 10 cm. The Winter Weather Parking Ban will be called to support clearing operations and will continue until the City issues notice that it has been lifted.

When a winter weather parking ban is called, the City issues a special advisory to the local media and posts it on ottawa.ca. The parking ban ends when snow clearing is completed, and the City issues an advisory indicating that it has been lifted.

Vehicles without a residential parking permit that are parked on the street during a parking ban may be ticketed and towed.

Impact on residential parking permit holders

If you have a residential parking permit, your vehicle is exempt from winter weather parking bans. Removing your vehicle from the street helps City crews clear the street faster.

Select Park and Ride locations

In partnership with our OC Transpo colleagues and our Roads and Parking team, we have opened up six park-and-ride locations with designated parking available during a Winter Weather Parking Ban. The locations are:

• Riverview (at Earl Armstrong)
• Innovation (at Innovation Drive)
• Chapel Hill
• Nepean Woods (at Strandherd Drive)
• Greenboro
• Leitrim

The locations have designated parking areas, clearly marked with directional signs and parking signs, indicating that Winter Weather Parking is available during a ban. These spaces will be opened to residents during the parking ban.

Where to park overnight 

City parking garages are available for overnight parking during a winter weather parking ban. Because of limited availability, parking lots have individual overnight parking hours, and parkers are responsible to retrieve their vehicle before the parking period ends. Vehicles left past the available overnight parking period will be subject to the parking lot’s applicable rate for the entire duration of their stay.

Payment at the machine is not necessary during the overnight ban. Please exit through the gate.

When roads and sidewalks get plowed

Snow removal is based on a road-priority system, with high-use roads and emergency and transit routes cleared first.

When roads get cleared

• Major roads, arterials and major collector roads: Plows are deployed at the start of accumulation.
• After the last snowflake falls:
  • Major roads, arterials and major collectors: Within four hours.  Roads will not be bare pavement during a storm.
  • Minor collector roads: Within six hours
  • Residential roads and lanes: Within 10 hours

Under extreme winter storm conditions (i.e. those that exceed normal conditions), snow and ice control operations will be carried out based on the capacity of resources in as continuous a manner as practicable. This will give crews the flexibility to provide relief in residential areas while simultaneously maintaining and clearing priority roads.

When sidewalks get cleared

After the last snowflake falls:

• Sidewalks in the downtown core: Within 6 hours
• Downtown residential sidewalks: Within 12 hours
• Residential sidewalks: Within 16 hours
• Intersections and pedestrian crossings: Within 16 hours
• Bus stops: Within 24 hours after clean up

If your sidewalk has not been cleared 48 hours after the end of a snowfall, please let us know by submitting an online service request. The City does not clear snow from driveways or private sidewalks leading to a residence.

Plowing through a winter storm

After a severe snow storm, operators may have to plow a street twice. Sometimes a grader or dump truck with front and wing plows will do a first pass, followed by a sand/salt truck, to clear a small amount of snow and make sanding/salting more effective.

To clear a cul-de-sac, operators will push the remaining snow to the centre or outside of the street, depending on the available area.

In the early winter, the City removes ruts that have formed on snow-packed surfaces. This keeps catch basin open and helps prevent flooding.

Salt and sand

The City applies dry salt, wet salt, sand salt mix, liquid brine and abrasive materials on streets. Salt is spread early during a snowstorm to make a brine solution that prevents the ice from sticking to the asphalt.

To minimize salt use, rock salt is sprayed with a liquid de-icer as it is spread. This speeds up ice melting by making the salt sticky so it can adhere to the road.

Anti-icing is used before or at the beginning of freezing rain or other winter precipitation. The de-icing solution consists of pre-wetted salt or a liquid solution. It is applied to the Transitway and Highway 174 to prevent ice from forming and bonding to the pavement.

Abrasive materials such as sand are used to increase traction in colder temperatures when salt is not effective.

Snow removal and disposal

The City aims to distribute snow on both sides of the road. Snow banks are removed or reduced in size when they begin to restrict sightlines, travel widths, and pedestrian and cycling traffic. Snow banks that restrict sightlines at intersections and at pedestrian, school and railway crossings are removed within 24 hours after crews are made aware of the situation. If weather permits, snow banks are pushed back to curbs to provide more driving width on the roads and to make space to store snow.

The City’s snow disposal facilities do not accept snow from private operators. To find private snow disposal facilities, consult the Yellow Pages, Greater Ottawa Truckers Association or Ottawa Construction Association.

Temporary no-parking signs

During planned snow removal, temporary "No Parking" signs are posted along streets to be cleared. This parking ban applies to all vehicles, including vehicles with residential parking permits. Any vehicle parked during a temporary "No Parking" ban will be ticketed and towed.

Potholes

For information about potholes, please consult our Road maintenance webpage.

Flood control

If the temperature rises above zero degrees Celsius in a short period of time, flooding can occur. The City maintains drainage systems to reduce potential flooding conditions. City crews remove snow and ice from catch basins on roads and sidewalks to ensure melting snow drains when required. It is normal for water to pool around a catch basin in wet weather. Roads are designed to drain based on the sewer capacity. Roadside ditches are cleared at the outlet end of the ditch system to provide drainage for the spring melt. 

The City is conducting a review of its Winter Maintenance Quality Standards (WMQS), with a focus on the maintenance standards for sidewalks and pathways, certain residential roads (to reduce rutting), and certain roads adjacent to schools where no sidewalks are available, and/or where there are bus stops. Learn more about the project and engagement opportunities here.

If you have current specific maintenance concerns, please submit a service request online.

• Do not push snow and ice on the street, sidewalk or park.
• Keep fire hydrants free of snow.
• Use wood, plastic or fibreglass driveway markers, which should be no larger than a hockey stick.
• Open catch basins or drains in front of your property when the weather becomes mild.
• Catch basins are identified by a yellow “T” bar painted on the roadway.

A snow windrow is a pile of snow that accumulates at the end of driveways and on the sides of streets during plowing. It is the responsibility of the home owner to remove their own driveway windrows.

Snow fences

Snow fences reduce the build-up of drifting snow and ice on roads, and improve visibility for motorists. The City installs wood-slat snow fences or partners with local farmers for corn or tree fences.

Plant a snow fence

The City encourages landowners who plant corn to participate in the Alternative Snow Fencing Program.

In late summer, participating landowners leave six to 12 rows of standing corn parallel to the road and 20 metres from the road’s right-of-way property line. In December, landowners are paid an amount based on the market value per tonne of the unharvested corn, the yield of tonnes per acre, the actual acres standing and for spring clean-up work

In non-agricultural areas, landowners can plant trees 20 metres from the right-of-way property line.

To find out more, please call 3-1-1 (TTY: 613-580-2401).

Place garbage containers and bags and recycling bins at the curb. Do not place them behind or on top of snow banks.

Garbage and recycling collection

Towed vehicles are usually moved to a nearby street where snow removal has already taken place. If you cannot find your vehicle, call 3-1-1.

To make sidewalks safe to walk on in the winter, the City provides do-it-yourself grit boxes close to steep hills and in areas where there are many pedestrians, seniors and persons using mobility devices. Residents are encouraged to spread the grit on slippery spots on sidewalks and other problem areas.

When the snow falls, City crews immediately start clearing the way for you. With such a large network of roads, clearing snow from City streets requires collaboration and support from staff and residents. Residents can help make the process safer for everyone. One way to help is to please slow down and let snow plow operators lead the way when you see a blue light. Below are some additional tips that you can follow to make our roads safe and clear of snow. 

• Be patient and keep a safe distance behind working snow plows.  Snow plows often travel slowly because they are removing snow, spreading salt or sand and applying liquid anti-ice to roadways. 
• Never pass a snow plow.  Snow plows are wider than the average vehicle with large blades that extend a metre or more ahead and into the neighbouring lane. Passing a snow plow on the right could result in severe and even fatal collisions. 
• Don’t drive beside snow plows.  Snow plows sometimes shift sideways when they are plowing packed snow or drifts which could put you at risk for a collision. 
• Move aside. Snow plows often drive along the centre line of a roadway to remove snow.  If you are approaching a snow plow from the opposite direction, shift right, if conditions allow, to ensure there is enough space for the plow to pass you safely. 
• Beware of reduced visibility. Even at reduced plowing speeds, a light powdery snow forms a cloud in the wake of a snow plow that severely restricts a driver’s visibility.  This makes passing extremely dangerous. 
• Do not pass between snow plows in tandem.  On multi-lane roads snow plows often work in tandem, forming an echelon or “conga line”.  Passing or weaving between these plows is dangerous.  Please stay well back of echelon plows. 
• Watch for snow plows on sunny days.  Snow plows and removal equipment are out for several hours and even days after a storm clearing shoulders and cutting back snow banks.  Please be aware of plows even on clear days. 
• Teach children to play away from the road.  The driver of a snow plow may not be able to see a child playing in the snow. 
• Children should never build snow forts or tunnels along the roadway.  Snow forts and tunnels may collapse or be pushed down by snow plows or removal equipment. 
• Pedestrians should ensure they are visible.  Pedestrians should move back from the road if they see or hear a snow plow approaching.

City Snow Vehicle Receives Sideguard Safety Device

The City of Ottawa's Fleet Services team recently completed the installation of a sideguard on a snow plow. This barrier, which was gifted to the City is intended to serve as an additional safety measure for cyclists and pedestrians.
