Toronto backflow test report and test tag
Toronto’s Municipal Code Chapter 851 requires the results of every backflow device test to be sent to the City on its form within 7 days, and a record card or test tag on the device. Devices are tested on installation, within 72 hours of a repair or service, when relocated and every year, following the CSA B64 series and AWWA procedures. A device that fails must be repaired within 48 hours.
When a test is required
- When the device is installed
- Within 72 hours of a repair or service
- When the device is relocated
- Every year after that
What the test tag must show
Section 851-8 lists the tag contents:
- Property address
- Device location, type and installation date
- Manufacturer, serial number and size
- Test date
- Tester’s initials and printed name, the employer’s printed name and the tester’s certificate number
Deadlines
The report goes to the City on its form within 7 days of the test. A failed device is repaired within 48 hours. The City accepts reports by email or online; check its current submission page.
How Stampario fills it

- The Canadian backflow report records every tag field (address, location, type, install date, manufacturer, serial, size, test date, tester and certificate number), so writing the tag takes seconds.
- It calculates the buffer (A − B) and has the owner’s signature line many Canadian forms ask for.
- Every device keeps its history, and next year’s test shows up on your call list.
Common questions
Can I send the City this report instead of its form?
The by-law says the City form. Use the City’s form or online submission for filing; the Stampario report is the owner’s signed copy and your own record, with the same readings ready to copy.
Who is responsible for submitting it?
The by-law puts the duty on the owner; in practice the tester submits it as part of the job.
