Pinus strobus – Eastern  White Pine – Measured at over 46 meters (> 150 feet) in height, the tallest tree in Ontario grows in Gillies Grove, a 56 acre old growth forest in Arnprior west of Ottawa.  This White Pine grows with other 130 foot plus tall pines along with huge Hemlocks and Sugar Maples.  Its DBH is 93 cm (2017), indicating that the tree put most of its energy into growing upward, likely competing for sunlight with other trees.
