The wooded area straddles Dollard-des-Ormeaux and the Montreal borough of Pierrefonds-Roxboro. The trees on the Pierrefonds-Roxboro side of the forest are protected from development, but the trees in neighbouring Dollard-des-Ormeaux are not.
"The entire forest will be very much affected by any construction here," said Sue Stacho, a Pierrefonds-Roxboro resident. "Trucks are going to come right through the Pierrefonds portion of the forest."
"We're going to lose at least a dozen very mature trees. The animals are going to [flee] while the work is going on."
Building would tower over backyards
Some DDO residents say they had no idea the residential development project was in the works until a sales office for the Sunnybrooke Station condominiums was erected recently.
"We bought the house thinking that we were at the end of the street surrounded by woods," said Martine Deserres, who says the six-storey project will back onto her property. "It's a nice neighbourhood. People are very friendly, and kids play around here so it's great for families."
"This condo, supposedly for young professionals, is going to throw off the vibe that we have right now."
A West Island environmental group has called on the developer to find other land to build on which won't require the destruction of any wooded area.
"The developer should be looking for some way to trade this for something of lower ecological value," said David Fletcher of the Green Coalition.
However, DDO city officials say there is scarcely any other suitable land to build on, and the city has preserved ample green space on the territory already.
The project developer did not return a call from CBC News.
