Parks, Forestry & Recreation
Toronto, the largest city in Canada has an urban forest with an estimated 10.2 million trees covering approximately 18,000 hectares. Forty percent of this valuable resource is situated on public property, including an estimated 3.5 million trees within our parkland system and approximately 600,000 trees on our streets.

Urban Forestry staff observed a significant loss of leaves in several forested locations across the City. Defoliation is caused by a caterpillar of a native insect, fall cankerworm. Defoliation is nearly completed and the caterpillars are moving to pupate in the soil.
Urban Forestry staff will monitor the affected areas this fall to determine further action.
Urban Forestry implemented the 2017 Gypsy Moth control programme. It included two aerial spray applications in selected areas on May 23 and May 27th.
The City will be assessing the success of the programme by monitoring the gypsy moth population and the extent of defoliation during the growing season.
