Maintenance and trimming

Homeowners are not permitted to work on City trees because of the risk of injury or the risk of damaging utilities.

Boulevard Tree Protection By-law P.-69

After you call for a tree to be trimmed, it will take a couple of weeks, depending on weather and available resources, for an inspection to take place. After the tree is assessed, work orders are prioritized by potential hazard and risk. The time it takes will depend on the weather conditions, crew allocations, the condition of the tree and the severity of the work that is required.

Lane maintenance

The City does not manage trees on back lanes. Property owners who border the lanes are expected to share the responsibility. There are no by-laws to enforce cost sharing arrangements.

Trees on unassumed lanes are not maintained. Upon request, the City may attend to a tree in declining health that may pose a hazard. The City Engineer decides on whether or not to take action and timing of any work.  

Bees, wasps and insects

The City does not spray for insects such as tent caterpillars. We will, however, remove wasp nests that are within 10 to 15 feet of the ground. The City works with Ontario Bee Rescue to re-home honey bees when a swarm is located on a City tree.

Trees and construction

Before construction begins, put plans in place to protect surrounding plants and trees.

  • Trees (including root zones) that have not been approved for removal must be protected from injury or destruction.
  • Do not park, operate, repair, clean or fuel equipment and vehicles within the dripline of trees not approved for removal.
  • Do not stockpile construction material within the dripline of any trees not approved for removal.
Protecting tree roots

Root cutting can have catastrophic results. Roots not only nourish the tree, but stabilize the trunk and canopy against falling over.

Set up Tree Protection Zones (TPZ)

Set up construction fences around all trees that are not being removed. The TPZ should be placed as far out as possible. Remember that the root systems extend much farther than the drip lines of the trees.

Installing the Tree Protection barrier Barriers for tree protection should be a minimum height of 1.2 m (4'). Use materials such as orange construction fence or snow fence supported by steel posts. The posts should be no more than 2.4 m (8') apart, and close enough to keep the fence erect and prevent the material from sagging. Snow fence with posts is acceptable. The barriers should be installed before the project starts and maintained in good repair until the project is complete. All fencing and posts must be removed upon completion of the work.
