The Canadian Coast Guard ensures that all ships plying Canadian waters, including the Arctic waterways, meet the requirements of the Canada Shipping Act and follow pollution-prevention procedures; it also operates icebreakers, which keep shipping lanes open, and provides service for the far north.
The Canada Wide Daily Standard for airborne particulate matter and ozone pollution, regulation PM2.5, is 30 micrograms per cubic metre.
Daily ambient concentrations of air pollution were obtained from the National Air Pollution Surveillance Network (NAPS) maintained by Environment Canada which collects outdoor air pollution levels through several automated fixed-site monitoring stations [ 17].
Canada: The NRC's Biotechnology Research Institute has an Environmental Biotechnology Sector that conducts research in prevention, pollution control, green technologies, and sustainable development.
The region is also subject to significant outputs of vehicular exhaust due to the Canada-US international crossing at Bluewater Bridge, and transnational air and water pollution from Ohio, Illinois and Michigan.
"According to Environment and Climate Change Canada's own numbers, this means an additional 23 to 28 MT of carbon pollution from the tar sands each year – the equivalent of putting 5.9 million cars on Canada's roads".
National exposure models were required by Carex Canada to produce population exposure assessments that captured both between-city and within-city pollution variability.
Daily air pollution levels were obtained from automated fixed-site monitoring stations maintained by Environment Canada as part of the National Air Pollution Surveillance Network [ 22].
In Canada, an annual reporting system has been developed in which time trends in the levels of outdoor air pollution are estimated annually, with each successive reporting year based on an additional year of monitoring data (Government of Canada 2006).
