Snow & Winter Weather Update: What We Need to Know

Snow is falling across Calgary, with 5 to 10 centimetres expected by Monday. For your safety, please be patient, allow extra time for travel, bundle up, and be ready for winter conditions on your commute. Calgary Transit is also implementing city-wide snow detours to keep service moving.

Road Conditions & City Response

The City’s crews have been working ahead of and during the snowfall to prepare equipment, apply anti‑icing materials, and focus on the most critical routes. Under the Priority Snow Plan, teams begin by tackling the busiest roadways before snow stops accumulating.

Once the snowfall ends city‑wide, a “snow clock” is activated. Here’s how it works:

• 0–18 hours after snowfall ends: Crews clear the busiest major roads, defined as those with more than 20,000 vehicle trips per day.

• 0–24 hours after snowfall ends: Hand crews clear high‑priority pedestrian infrastructure—overpasses, sidewalks beside city properties, major bus pads and LRT platforms.

• 18–36 hours after snowfall ends: Crews shift to high‑volume community and transit routes (roads with more than 5,000 vehicles per day) and other vital intersections or bus routes.

• 36 hours and beyond: Attention turns to lower‑volume roads, residential streets (which are maintained to a hard snow pack), and remaining bus stops or ramps.

Please note: major provincial highways such as Deerfoot Trail and Stoney Trail are maintained by the Province, not the City.

If you’re driving, walking, wheeling, or using transit, please slow down, be patient, give yourself extra time, and pack winter essentials to help ensure a safe commute for everyone.

Calgary Transit: City-Wide Snow Detours in Effect

To ensure transit service stays as safe and reliable as possible, Calgary Transit will activate snow detours city-wide for the commute on Monday, November 24, beginning with the first trips of the day. This proactive approach helps prevent buses from getting stuck and reduces delays for riders.

What to Expect

• City-wide snow detours start Monday morning and will stay in effect until conditions improve. Detours may be lifted city-wide or by quadrant once operations stabilize.

• All transit school routes will continue as normal and are not impacted by snow detours.

• Crews are preparing LRT and MAX platforms, sidewalks, stairs, Transitways, parking lots and bus loops throughout the storm.

To find out if your route is affected, visit the full list of detours and maps at: calgarytransit.com/snowdetours.

Be a Snow Angel

Snow Angels is a volunteer initiative that encourages Calgarians to “adopt a sidewalk” and help clear snow for neighbours who may struggle - especially older adults and those with limited mobility. It’s a simple but powerful way to show community care: when snow falls, Snow Angels lend a hand to keep sidewalks safe and accessible. The City also helps recognize these everyday heroes with free downloadable certificates, and participants are invited to share their stories on social media using the hashtag #YYCSnowAngels.

Stay Updated

Motorists are advised to check The City’s Traffic Cameras and Road Conditions Map.
