The tree, a 350-year-old oak, has been around longer than Canada, easily predating Confederation in 1867, according to an arbocultural assessment.

Save the date! Join us on November 2 in Thornhill, ON for discussion about how we can look at urban forest issues in new ways. We've got some great talks in the works and would love to hear from you if you have news to share with the community.

Construction can be harmful to surrounding trees if protective measures are not taken. If your tree has been affected by construction, be sure to hire an ISA certified arborist to assess its viability and risk potential and recommend treatment. #isaontario treesaregood.org/portals/0/d…
