Please contact 311 to discuss the accuracy of your water meter. Toronto Water will determine if a water meter accuracy test is necessary.

If the meter is over-registering, the test is free. If the test is under registering or registering accurately, there is a fee.


If the meter is at the weighted acceptable average you will be billed on your next water bill.

Depending on the meter size testing can take 1-2 hours. Results are usually mailed to you within 3-4 weeks. Once the meter has been tested, the results are documented and the meter held for 6 months.
