Felling/Treating ash trees
In September 2015, City Council adopted its first strategy to fight the emerald ash borer in order to preserve the urban forest, maintain the canopy, and protect biodiversity.
Any ash tree of which more than 30% of the branches are dead must be felled. It is important to act quickly, because a dead ash tree is dangerous and more costly to fell. Before felling, you must obtain a permit, which will be issued free of charge.
Felling period: October 1 to March 15.
A grant is provided to homeowners for the felling of ash trees whose diameter is 25 cm or more. The grant covers 50% of felling costs, up to a maximum of $500 per tree.
To get the grant
Send the receipt confirming payment to the Public Works Department, which will issue the grant by email to the person whose name appears on the receipt.
So far, preventive treatment with TreeAzin is the only action recommended by experts that offers a relatively effective protection against the emerald ash borer. The treatment involves injecting an insecticide at the base of the trunk that will have an effect on the tree for two years. If your ash tree(s) have already been treated, you can continue treatment this year; however, no new treatments will be started.
A special price is available for residential properties. Homeowners should contact the Public Works Department.
- Deadline to request an inspection: August 15
- Deadline to take advantage of the special rate: August 31
Homeowners are eligible for a grant covering 50% of the treatment cost, up to a maximum of $1,500 over two years for each residential address.
The treatment must be applied between June 15 and August 31.
To qualify for the grant
- 1. If your ash tree(s) have already been treated, contact the Public Works Department at 514-630-1230 to have your ash tree(s) inspected.
If the need for treatment is confirmed, a company selected by the City will apply the treatment at the agreed rate. Any other firm qualified to apply the preventive treatment can be selected, using the same procedure and the same rate.
- 2. Send the receipt confirming payment to the Public Works Department, which will issue the grant by email to the person whose name appears on the receipt.
