BEFORE and AFTER: rebuilding Vaughan’s tree canopy one timber at a time

Making progress on the City’s 2015 Tree Replacement Plan

Did you know that Vaughan lost approximately 19,000 trees over the last couple of years due to the 2013 ice storm and the ongoing Emerald Ash Borer infestation?

The December 2013 ice storm is not a memory many would like to revisit – it caused devastating damage to the City and surrounding areas and left many without power for days. Trees – young and old – were torn apart and collapsed. Approximately 18,900 trees required maintenance and 13,600 more required replacement as a result of that storm.


For those who are unfamiliar with the EAB species, it’s a foreign insect that attacks and kills all ash trees in North America. These little green critters eat up tree tissue beneath the bark, cutting off the tree’s water and nutrient flow. Once they settle into an area, ash trees are expected to die within 10 years. To take action against them, affected trees and surrounding trees must be removed. To date, more than 1,680 ash trees have been removed in Vaughan and there are approximately 16,000 remaining that are vulnerable to the ongoing EAB infestation.

So what is Vaughan doing?

To prevent huge losses from future infestations of other foreign species, the City is adding a variety of trees to every street. Afterwards, regular inspection for newly planted trees will ensure strong and healthy growth. This is part of Vaughan’s 2015 Tree Replacement Plan to restore our community’s trees.

This year, the City is planning to replant half of the residential trees lost and there is good news for residents anxious to find out if they will be receiving trees. The list of streets has been updated to include more locations this fall. Check our website to see if your street has been added.

This is the first step in rebuilding the City’s tree canopy. Each year, the plan will be revisited and readjusted according to the City’s budget so Vaughan’s neighbourhoods can enjoy healthy and beautiful trees.

(Vaughan is adding diversity to its new trees to prevent large numbers of losses from future infestations. The Tree Replacement Plan is well underway to restore trees on residential streets.)

  1. Too bad Vaughan is planting so many dwarf trees that don’t grow past 20 feet! Such as Ornamental Pear, Amur Maple, Serviceberry, etc… You can still have diversity by planting mainly large growing trees. Guess the city sees it easier to have mini trees. So dumb!
