This past summer, an IGA store in Montreal’s Saint-Laurent borough erected “the largest organic green roof garden in the country.” It is about 25,000 square feet and it has a soil depth of only 150mm.
They also claim that it’s the first supermarket in Canada to sell produce grown on the roof of the actual store. The brand: Frais du toit, or fresh from the roof. There’s even a livestream in the vegetable aisle showing you how the goods are doing overhead.
I would be curious to know what their yields are like and what they are charging for the produce. But it’s certainly a praiseworthy initiative.
Below is a quick video that will give you an idea of what the roof looks like. If you can’t see it, click here.
