In Ontario, backflow prevention is a critical measure to ensure the safety and quality of our drinking water. Regulated by municipal by-laws and the Ontario Building Code (OBC), these programs are designed to prevent contamination of the water supply, ensuring the health of the community. Municipalities enforce these regulations, with penalties for non-compliance.

Each municipality in Ontario may have specific requirements for backflow prevention, including mandatory testing, installation, and maintenance of backflow prevention devices. It’s important for property owners and business operators to be aware of the unique regulations in their area.
