Content: Pollution from oil wells
In southeastern Saskatchewan, air pollution from oil production has breached provincial air quality standards hundreds of times since 2014. Canada/United States transboundary pollution
In recent years, the Canada-United States Air Quality Agreement, signed on 13 March 1991, has improved air quality by reducing sulfur dioxide and nitrogen oxide emissions in both countries. The agreement was meant to address the issue of transnational air pollution between the two countries. The agreement was expanded in 2000 to also include goals of reducing emissions of volatile organic compounds and levels of ground-level ozone. Ground-level ozone is caused by reactions between nitrogen oxides and VOCs in the presence of sunlight. Ozone is a contributor to smog and is known to cause numerous respiratory diseases. The 2012 Canada-United States Air Quality Agreement Progress Report found that "Canada's total emissions of sulfur dioxide have decreased by 57% from 1990 levels while the U.S. has reduced total sulfur dioxide emissions from covered sources by 67% from their 1990 emission levels. Between 2000 and 2010, Canada reduced total emissions of nitrogen oxides by 40% in the transboundary ozone region while U.S. total nitrogen oxide emissions decreased by 42% in the region". While transnational pollution between the United States and Canada has decreased many Canadians still say they contend with polluted air as a result of drifting pollution from the U.S. In 2006 the government of Ontario announced that "5,000 premature deaths caused by smog in the province every year can be attributed to air pollution that crosses the Canada-U.S. border." Additionally, the then (2006) mayor of Halifax, Peter Kelley, also proclaimed "over 50 per cent of air pollutants over New Brunswick and Nova Scotia are from the U.S. For us, we're trying to deal with what's coming our way, but also what we generate here as well."
