New trees coming to Waterloo boulevards this fall

September 3, 2026

Starting in October, we will be planting almost 700 trees in suitable boulevard spaces that have not previously had trees.

This work will add more trees to our neighbourhoods while helping us learn what planting methods work best for trees growing in the challenging conditions of a city boulevard.

Why are we planting trees on boulevards?

Adding trees to boulevards can provide shade, help cool neighbourhoods, support biodiversity and contribute to a healthier urban environment.

Why do some of the trees look so small?

Some of the trees being planted this fall will look smaller than usual because they are part of a trial using a new method that focuses on air-pruning. This is a process that encourages a stronger, more naturally structured root system, which reduces root damage during planting and helps the tree establish more quickly.

While the trees may start smaller, research and experience suggest that air-pruned trees can catch up to traditionally grown trees within a few years. We’ll be monitoring their growth and survival to see how they perform in Waterloo’s boulevard conditions.

Can I choose which type of tree is planted near me?

We know residents may have preferences about the trees planted near their homes. However, to make sure trees are appropriate for each location and can thrive over the long term, we will be selecting the species based on the specific site conditions.

Factors such as available space, sunlight, soil conditions, overhead wires and underground infrastructure all help determine which species is most suitable.

Why is the City trying a new planting method?

For the past four years, the City of Waterloo has participated in an innovative research consortium through the Vineland Research and Innovation Centre. This has given our Forestry team access to current research and new approaches to growing and establishing urban trees.

This trial gives us an opportunity to test the approach in real Waterloo conditions before considering whether it should become part of our standard tree-planting practices.

We’ll be monitoring the trees over the coming years, including their growth, establishment and survival, to help inform future planting decisions.
