Dec. 22, 2022 – The City of Sarnia is preparing to deploy winter road maintenance resources in response to a Winter Storm Warning issued by Environment Canada.

The City operates a fleet of 17 plows, five sidewalk plows, and four parking lot plows, in addition to utilizing the support of snow-removal contractors as needed.

Snow removal is prioritized on designated primary routes to ensure the delivery of transit and access for emergency services. Secondary roads are cleared after primary routes have been completed. Sidewalks not on priority maintenance routes are not maintained from Nov. 1 to April 30. For more information on snow removal processes visit

Residents are reminded that overnight parking on City streets is prohibited during winter months to facilitate snow removal.

Weather may also impact Sarnia Transit service delivery, leading to delays or detours. Updates will be shared via the City website and social media.

Environment Canada is predicting a major winter storm, beginning with snow and/or rain, this evening and continuing through Friday into Saturday. Potential hazards include:

  • Wind gusts of 90 to 100 km/h creating widespread blowing snow and significantly reduced visibility
  • Snowfall amounts of 5 to 15 cm by Friday night
  • Wind chill values as low as -20C
  • A flash freeze producing icy and slippery surfaces

Environment Canada advises residents to consider postponing non-essential travel.

Residents are also reminded to be prepared for any possible emergency, including extreme weather events, by having a home emergency preparedness kit including enough food, water and prescription medication for at least 72 hours. When travelling it is advised to stock a vehicle emergency kit. For more information visit
