Back in 2006 we first looked at how Green Roofs were becoming a development issue in Toronto, in 2009 Toronto implemented that green roof bylaw. Then in 2014 we took a look at how North America’s green roof industry is growing.
This year, Toronto has become the hub for green roofs! Torontist took a look into what made this happen and why green roofs are perfect for cities.
There are approximately 500 green roofs, big and small, in Toronto. This is thanks to a 2010 bylaw [PDF] requiring all new developers to cover between 20 and 60 per cent of their buildings with vegetation. It’s the first (and, for now, only) regulation of its kind in North America, making Toronto uniquely positioned for environmental design.
The bylaw is why the 41-story RBC WaterPark Place [PDF] at Bay Street and Queens Quay has three green roofs that together could fill a NFL football field.
Developers can opt out of installing anything remotely grassy for a fee. But Jane Welsh, City Hall’s project manager for environmental planning, told Torontoist only five per cent of buildings choose to go sans-green roof.
Welsh also says municipally-owned buildings install a green roof anytime there’s a repair or replacement to the top of the building, when feasible.
