By-law to stop the spread of the emerald ash borer

Coloured markings are often used to monitor and plan operations on public trees. These colours may indicate a pesticide treatment, pruning, felling or another intervention. Each borough has its own colour code. To learn more about operations on trees in your area, contact your borough.

Important message:

In order to limit the spread of the emerald ash borer, the city asks residents to not place deciduous tree branches in their garbage can or green waste bag. They should be placed on the curbside in unattached bundles, and you should call 311 to have them picked up. Thank you for your valuable cooperation.
