Backflow requirements in Toronto
In Toronto, backflow prevention is governed by the City’s Water Supply By-law (Chapter 851). Owners of industrial, commercial, institutional, and Part 3 residential properties — as well as construction sites — must install a backflow preventer and have it tested by a certified Cross-Connection Control Specialist.
- Testing required at installation, annually, and within 72 hours of any repair
- Devices selected by hazard level under the CSA B64.10 standard
- Results submitted to Toronto Water by a certified tester
- Applies to ICI and Part 3 residential properties plus construction sites
Toronto operates one of the most established backflow prevention programs in Ontario, and the City actively follows up on overdue testing.
