Reporting a spill — immediate steps

Prioritize safety: evacuate or isolate the area, avoid contact with unknown substances, and call 911 if there is immediate threat to life or property. After ensuring safety, contact City of Guelph reporting so staff can coordinate an inspection and response[1]. For spills that may affect the environment or waterways, also notify Ontario’s pollution reporting line as required under provincial rules[2].

If anyone is injured or fumes are present, call 911 immediately.

Specific monetary fines, escalation of penalties for repeat or continuing offences, and exact section references are not specified on the cited City pages; see the official links below for department contact and procedure details[3].

  • Monetary fines: not specified on the cited page.
