This website gives you fast, easy access to detailed records of air pollution, water quality, climate conditions and land use for hundreds of communities across Canada. All the data on this site were collected by provincial and federal government agencies. The Sources page gives you more information about where the data come from and what some of the technical terms mean.
The first edition of this website was developed in winter 2014 by Professor Ross McKitrick at the University of Guelph,
with funding support from the Research Fellowship in Sustainable Commerce at the College of Business and Economics.
The new edition was designed by Professor McKitrick in 2017 and developed by Sandbox Software Solutions.
Additional funding support has been received from the Donner Canadian Foundation, Davis Engineering Ltd
and the Frontier Centre for Public Policy.
Air pollution data is divided into Pollutant Concentrations (the levels of contaminants in the local air measured at hundreds of places across Canada) and Annual Emissions (releases of contaminants into the air).
