On November 20, a fire in a vacant industrial building in Cambridge, Ontario caused odours here in Guelph.
The Ontario Ministry of the Environment is on-site monitoring air quality, and people can resume outdoor activities unless they experience coughing or throat irritation.
Odours may persist through the day.
The Guelph Fire Department responded to several calls Monday evening and asked people to stay indoors to avoid the odours.
