Pruning and felling (requirements and ideal times)

Conditions for obtaining a felling permit

Under the by-law, you must apply for a felling permit and fell your ash before December 31 of the current year if it is in one of the following conditions:

  • It is dead
  • It is in poor health and 30% or more of its branches are dead

You can also request a felling permit if your ash tree meets one of the following conditions:

  • Your ash tree is affected irreversibly by a disease or pest
  • It poses a threat to people's safety
  • It could seriously damage property
  • It impedes a construction project authorized by the city

4 easy steps to fell an ash tree in compliance with the by-law

  1. Apply for a permit in your borough.
  2. Once you have received your permit, get estimates for your felling.
  3. Have your ash tree felled ideally between September 15 and December 31. If you can't wait until September 15, consult the high-risk materials section. Special measures apply to felling ash trees in the summertime.
  4. Dispose of ash wood as directed in the by-law .

Tip : Because of the risks associated with felling a tree, make sure your contractor has good liability insurance. See the Web site siaq.org to find qualified contracots.

Pruning an ash tree

You can prune your ash at all times. However, the ideal time for pruning ash is between 15 September and 15 April. Pruning wounds made outside this period may attract females looking for ash trees weakened to lay their eggs.

Please note that special procedures apply to the pruning of ash trees. Consult the high-risk materials section for more information.
