Seven years ago, the city of Toronto committed to transforming its urban area by passing the 'Green Roof Bylaw' thus becoming the first city in North America to do so. It requires every new commercial, residential and institutional development with a minimum of Gross Floor Area of 2,000m2 to vegetate at least 20 per cent of its rooftop. Basically, the bigger the GFA the more of the rooftop has to be vegetated.

From February 1, 2010 - March 1, 2015, 260 green roofs have been created in Toronto, consisting of 196,000 sq m of green roof area. A total of 444 green roofs exist in the City of Toronto.

The reason behind Toronto's decision to implement the bylaw resulted from the 2004 study done by the Ryerson University. Among the environmental benefits they found out about are:

Reduction in stormwater runoff that affects quality of local water resources which supply drinking water, are used for swimming, and serve as fish and wildlife habitat

Reduction in energy consumption

Reduction in the urban heat island effect and associated cooling costs

Beautification of the City

Creation of more natural green spaces

Opportunities for local food production

Our photographer Vivian set out on a tour of some of these eco-friendly green rooftops. Enjoy the views and let us know if we missed your favorite place!

The Big Carrot/Carrot Common

Come and relax after shopping. Rent this unique downtown space for your private event. Just come and walk through and admire what can be done when people work together. You'll be amazed to find ample seating, gardens, water fountains, and if you give it long enough.... yourself.
