​​The Emerald Ash Borer is an invasive insect that kills all types of healthy ash trees. The insect was discovered in York Region in 2008 and the City of Toronto a year earlier. While the Emerald Ash Borer poses no risk to human health, it is a significant threat to our forests.

The Town has contracted with Trugreen to provide treatment services to combat the spread of the Emerald Ash Borer (EAB), an invasive insect that kills healthy ash trees.

The contract will provide for the preventative application of TreeAzin, a pesticide approved in Canada that has shown to protect ash trees from the EAB. Approximately 2,000 publicly-owned trees along boulevards and rights-of-way have been identified in the Town's street tree inventory as potential candidates for treatment. Trees meeting the treatment criteria will be marked by Town staff with a small but highly-visible painted dot.
