A bylaw proposed in Toronto that would require some buildings to have green roofs was expanded to increase the number of buildings that must sport rooftop gardens. Supporters say the proposal, which requires green roofs for buildings six stories or higher, will help reduce greenhouse gases and summer temperatures. The revision also lowers the minimum square footage of a roof that must incorporate a garden. Some developers oppose the plan and say it conflicts with zoning rules and is expensive enough to drive businesses away from Toronto.
