The Emerald Ash Borer left many trees in Mississauga devastated.

Dead ash trees are located on properties across Mississauga and may only become apparent now, as their leaves haven’t returned after winter.

If an ash tree is identified as a source of danger on private property, a Property Standards Order (PSO) will be issued by the City for you to have the tree removed. If you receive a PSO, you need to arrange to have the tree removed, but are not required to get a permit to remove the tree in question.

Ash trees on private property are the responsibility of the property owner. However, because of the increased demand on tree-removal services, municipal law enforcement officers will be providing up to 120 days to bring the property into compliance, instead of the usual 30 days.

On City-owned properties, forestry crews have begun removing ash trees infested with Emerald Ash Borer, which are marked with an orange X. Work has begun in the following Ward 5 parks:

  • Westwood Park
  • Max Ward Park
  • Brandon Gate Park
  • Northwood Park
  • Derry Greenway Park
  • Elmcreek Park
  • Father Jospeh A. Nolan Park
  • Malton Greenway

Crews will be working Monday to Friday from 7 a.m. to 5 p.m. After the initial tree removal, crews will remove the tree stumps, repair the ground with topsoil and reseed. All works will be weather dependant.

All City-owned trees on streets and in parks that are removed due to Emerald Ash Borer will be replanted within the community. Some street trees may need to be replanted in another location due to changes in underground utilities.
Trees will be replanted approximately one year after the stump is removed. However, timing is approximate due to the short planting season and weather conditions.

Ward 5 is expected to receive quite a number of new trees because many trees were lost to Emerald Ash Borer and the 2013 ice storm. If you have any questions or comments, please feel free to contact my office at 905-896-5500 or visit
