From green roofs in Toronto to Vancouver’s rain city strategy, Canadian cities are looking to become sponges in order to help mitigate some of the effects of extreme rainfalls. In Montreal, Mayor Valerie Plante announced last week that the city plans to develop some 30 additional sponge parks designed to catch and absorb rainwater and keep it from flowing into overburdened sewers during extreme rain.
Here's a snapshot of some of Canada's salty waterways harming ecosystems
A number of Canadian cities have exceeded acceptable chloride levels in watersheds in recent years, raising concerns about the impact on freshwater wildlife and other species. The problem largely stems from road salt and saline solutions, which have a chemical compound of chloride to keep roadways safe during winter weather.
Smaller Canadian cities rank high on environmental scorecard that has a few surprises
A new environmental scorecard says Canada's biggest cities have lower scores than most small and medium-sized municipalities, but a closer look at the data reveals some surprises. The study, published Tuesday in the journal Environment International, rates 30 of the country's largest cities and towns on nine indicators related to health, including air quality, heat and cold waves, ultraviolet radiation, and access to green spaces. The results are compiled in the new Canadian Environmental Quality Index, produced by Dalhousie University in Halifax.
