What Redevelopment Actually Does To A Mature Tree
A lot severed for a new build, or a smaller house replaced with a larger one, usually means excavation, grading and heavy equipment moving through the same soil a tree's roots have relied on for decades. Even when nobody touches the trunk directly, compacted soil and severed roots can kill a tree slowly over two or three years - long after the construction crew has moved on and the connection is easy to miss.
Willowdale's mix of older postwar homes and newer infill means this pattern shows up constantly, on your property or the one next to it, which is exactly why we look at root zones and drip lines before any nearby digging starts, not after a tree starts declining.
The New Rules On Large And Replacement Trees
As of September 2026, a tree over 61 centimetres in diameter now falls into a distinct protected category, and the City can refuse a permit to remove or injure one outright. Any replacement tree planted to satisfy a permit condition is protected the moment it goes in the ground, with no grace period before the rules apply. A stump 40 centimetres or wider is now treated as proof the tree was protected, closing the old loophole of cutting first and measuring later.
We factor all of this into a quote up front, including flagging a large tree on your property that might qualify for the new distinctive-tree protection before you plan around removing it.
