Canada-US Air Quality Agreement
  • The Agreement between the Government of Canada and the Government of the United States on Air Quality (AQA) was signed and enforced in March 1991 in order to combat the cross-border air pollution and its lingering impacts, which, at the time, was acid rain.
  • To combat these effects, Canada and the US signed this agreement in 1991, and a decade later, the agreement was updated to include ground-level ozone to reduce smog.
  • Both countries promised to reduce their emissions of sulphur dioxide and nitrogen oxide and significant progress has been reported since the establishment of the Agreement.
