Canada’s Coolest Cities examines what Montreal, Ottawa, Toronto, Calgary, Edmonton and Vancouver are doing to encourage low-carbon transportation choices, such as walking, cycling, taking public transit and travelling shorter distances. The report indicates that all of the cities are tracking GHG emissions and setting targets. However, between 2001 and 2006, population grew much faster in the larger metropolitan area than in any of the core cities. People are moving to the suburbs. The data showed that these metropolitan areas also had lower fractions of commuters using transit, biking or walking than the core cities.
