Emergency response contained leak; residents urged to stay cautious
Emergency services in Greater Sudbury spent Wednesday addressing a natural gas leak in the Minnow Lake area that prompted precautionary evacuations and a temporary road closure.
Firefighters with the Greater Sudbury Fire Service, the department’s hazardous materials team and technicians from natural gas distributor Enbridge were on scene at Bancroft Drive near 2nd Avenue after authorities detected a high concentration of natural gas coming from sewer drains earlier in the day. Greater Sudbury Police Service also attended the incident.
| Detail | Information |
|---|---|
| Location | Bancroft Drive near 2nd Ave., Minnow Lake, Greater Sudbury |
| Evacuations | 12 buildings evacuated as a precaution |
| Road status | Bancroft Drive closed earlier; reopened at 2:30 p.m. |
| Ongoing actions | Hazmat monitoring and air-quality assessment on site |
City spokespersons and emergency services used social media to alert residents early in the morning. The incident was traced to gas seeping through sewer drains; crews focused on monitoring air quality and ensuring the leak did not pose a broader hazard to nearby homes and traffic.
- 12 buildings were evacuated as a precautionary measure.
- Bancroft Drive was closed at the intersection of 2nd and 3rd avenues during operations and later reopened.
- Hazmat teams and Enbridge remained on site to assess and monitor the situation.
By mid-afternoon, officials reported Bancroft Drive had been reopened to traffic at 2:30 p.m. Fire crews, however, remained on scene to continue monitoring and to provide public-safety oversight while assessments continued.
For residents in and around Minnow Lake, the response serves as a reminder of the intersection between municipal infrastructure and utility systems. Natural gas entering sewer systems is an unusual pathway for leaks and can complicate detection and mitigation, since it may travel through underground pipes and escape at manholes, drains or vents.
Local authorities urged anyone who noticed the smell of natural gas to call emergency services immediately and to keep a safe distance from the affected area. Residents who were evacuated were moved away from their buildings until crews could assure that immediate risks had been reduced.
While the immediate closure has been lifted and evacuations were precautionary, the presence of hazmat units and a utility representative on site indicates follow-up work and monitoring will be required to ensure there are no lingering hazards. Crews also advised motorists and passersby to exercise caution near the site while operations continue.
Sudbury’s public safety agencies have not released a detailed timeline for when all monitoring will be complete, but the reopening of Bancroft Drive and the continued presence of emergency personnel suggest the situation had been stabilised by mid-afternoon. Residents seeking up-to-date information should monitor official Greater Sudbury social channels and local media for any further advisories.
The incident underscores the importance of coordinated responses between the city’s fire service, police and private utilities when infrastructure issues have the potential to affect public safety in neighbourhoods that bridge Sudbury’s urban and suburban landscapes.
