The federal government confirmed Friday that it will match the United States on rules regulating emissions from vehicles.
The new standards are designed to reduce air pollution from passenger cars and trucks beginning in 2017. They will be phased in between that year and 2025.
Canadian regulations on the amount of sulphur in gasoline will also be harmonized with U.S. rules.
The new regulations on gasoline will require oil companies to reduce the amount of sulphur in gasoline to 10 parts per million by 2017 from the current level of 30 parts per million.
