The best green buildings in Toronto are a LEED certified bunch. LEED,

 if you're wondering, means Leadership in Energy and Environmental Design and helps recognize sustainable structures in Canada and around the world. And in fact, many of the city's massive office towers are actually working hard to be environmentally friendly. Here are the best green buildings in Toronto.

George Brown College Waterfront Campus This stunning building is home to higher education and lots of environmentally friendly initiatives. The George Brown College Waterfront campus has won multiple awards for being green. It's LEED Gold certified and fits in well with its natural, lakeside community.

TD Centre This six building complex in the Financial District might seem sprawling, but it's actually pretty environmentally friendly. It's LEED EB:O&M (Leadership in Energy and Environmental Design for Existing Buildings: Operations and Maintenance) Platinum certified and even has a green roof.

RBC Waterpark Place RBC Waterpark Place not only boasts great views of Lake Ontario, but it's also a LEED Core and Shell Platinum building. It features a slew of sustainable features, includes a 7,500 square foot green roof, lots of bike racks and efficient lights and other materials.

Royal Bank Plaza This building underwent a number of changes in order to get LEED Gold certified. It has efficient lighting, a robust recycling program as well as hand-free faucets and low-flow toilets and urinals to reduce water consumption.

The Berczy This condo building is located right by the St. Lawrence Market - but that's not its only farm-fresh, green feature. The developers, for instance, used sustainable materials as well as energy efficient electrical systems in this residential building to make it as environmentally friendly.

Barrymore Building You'll find more than just furniture at this showroom in Liberty Village. It's home to West Elm and the Knoll showroom, which is LEED-CI Platinum certified (AKA super green), thanks to initiative like a dedication to using post-consumer materials and ensuring lots of natural light.

320 Front St. West Complex This office building near the Rogers Centre (and other major downtown destinations) might date back to 1989, but that didn't stop it from getting LEED Platinum certified. Apparently going green is ageless.

Simcoe Place Green Curry might be delicious, but it's not even Simcoe Place's greenest feature. The building is LEED Gold certified after it adopted a number of sustainable programs.

Evergreen Brick Works One of the main spaces at Evergreen Brick Works is literally called the Centre for Green Cities. It's LEED Platinum certified and serves as centre for the Brick Works multitude of sustainable initiatives.
