Green Roof in Toronto?

I posted this in Home and Garden a few months ago but never got a response.

Has anyone come across a Roofing Company in Toronto that does Green Roofs?
I will need to be replacing the flat part of my roof in the spring and am very interested in a green roof.

Thanks in advance for any leads.

If you want to put a green roof on your house, you will need the services of at least an architect (to design the roof assembly for waterproofing and drainage) and perhaps a structural engineer, to verify that your home's structure can take the weight of the soil medium fully saturated with water.

http://www.greenroofs.net/ is a good resource; there is a search engine where you can find qualified design professionals and perhaps some contractors.

looks neat good luck
