The air quality data analyzed in this report came from the National Air Pollution Surveillance monitoring network, consisting of air monitoring stations in most cities with populations of over 100,000. Monitoring is conducted for sulphur dioxide, nitrogen dioxide, carbon monoxide, ozone, suspended particulates, lead, and soiling index. This report analyzes monitoring data to determine national trends in average and peak concentrations of these contaminants on an annual basis for the last 10 years (1978-87). Data were also compared with the National Ambient Air Quality Objectives which define levels of contaminant concentration of maximum desirable, maximum acceptable, and maximum tolerable.

The book's primary aim is to determine whether Canada and the United States have become more similar as their economies have become more integrated and their societies more diverse. The authors conclude that, although powerful economic and social pressures clearly constrain national governments and lead to convergence in some areas, distinctive cultural and political processes preserve room for distinctive national responses to important problems of the late twentieth century. Authors include Keith Banting, Paul Boothe (University of Alberta), Marsha Chandler (University of Toronto), George Hoberg, Robert Howse (University of Toronto), Christopher Manfredi (McGill University), George Perlin (Queen's University), Douglas Purvis (Queen's University), Richard Simeon, and Elaine Willis (consultant, Toronto).
