The six trees stand at the front of Lambton Park Community School facing Bernice Crescent, on the street-facing frontage, viewable and reachable from the public sidewalk without entering school grounds.

Zhelevo, the Coral Gable Drive Red Oak
Northern Red Oak (Quercus rubra). roughly 300 years. Free once open. The City of Toronto bought the private lot specifically to save this tree and is building a public parkette on it; as of the City's own July 2026 project update the house has been demolished and construction is underway, with opening projected Spring 2027. Until then the tree (which visibly dwarfs the former house from the street) is viewable from Coral Gable Drive but the lot itself is a construction site, not yet open ground.
