Stormwater Management, Aesthetics & More

The largest commercial green roof in the Greater Toronto Area (GTA) was designed as part of Sherway Gardens’ Stormwater Management Program. It is one of the measures that helped Sherway earn BOMA Best Gold and LEED certification for its expansion.

Aesthetics, too, were a big selling point. Sherway’s roof is visible from the junction of the Gardiner Expressway, the QEW and Highway 427, and from nearby condominiums. The much needed green space in this industrial part of the GTA improves the view for commuters and residents alike.

Urban Habitat

The lightweight and soilless vegetated green roof by Next Level Stormwater Management was installed in 2013 and is a natural oasis for pollinators, and migratory and non-migratory birds alike.  Watch aerial video of Sherway and other GTA green roofs, here.
