Smoke testing of the sanitary sewer system in Ward 1 from Lakeshore to the Queensway between Cawthra and the Etobicoke Creek.

What are we doing?

The Region of Peel have retained Infrastructure IntelligenceServices (I2S) to complete smoke testing within your neighbourhood. The area to be tested is shown on the map.

The test will be performed as a first step to identifying the connection points for roof downspouts, catch basins, and other water inlets (i.e. to the sanitary sewer or storm sewer).

Testing in your area (see map on right) is expected to start the week of October 26th and is expected to last two (2) to four (4) days. A staff member will come to your door on the day of testing.

What is Smoke Testing?
Smoke testing is a safe, quick way to identify connections. The smoke used in the test has no odour, isn’t harmful to your health, and will disappear in a few minutes.

What do I need to do?

  • Check to see that all plumbing traps under sinks, washing facilities and floor drains have water in
    them. Pour a few cups of water into your basement floor drains, and any sinks, showers, or other
    plumbing fixtures when you receive this notice.
  • If smoke enters your home and it is a nuisance to you, leave the affected room until testing is
    completed (10-15mins).
  • If you, or any member of your family, have a health condition that you feel we need to be aware of
    please contact the Region of Peel at 905-791-7800, ext. 4409.

The fire department will be notified of the streets being tested. If you have doubt about the origin of smoke, always contact the fire department at 911 or non-emergency communications line at 905-456-5700.
Should you have any further questions please contact Seth Monczka at the Region of Peel at 437-522-4062 or For more information visit, or follow us on twitter @peelpublicworks.
