Detailed explanation-1: -Emissions Over Time Fuel for electricity and heating, as well as non-ferrous smelters (producing such metals as nickel and copper are the largest sources of SO2 emissions in Canada, followed closely by emissions produced by the oil and gas sector.
Detailed explanation-2: -Many of the waters (streams, rivers, ponds, and lakes) and soils in Canada lack natural alkalinity, such as a lime base, and cannot neutralize acid naturally. Provinces that are part of the Canadian Precambrian Shield, such as Ontario, Quebec, New Brunswick, and Nova Scotia, are most affected.
Detailed explanation-3: -Emissions of sulphur dioxide (SOx) and nitrogen oxides (NOx) from coal-and oil-fired power plants, smelters, motor vehicles, and other human-related sources are the principal contributors to acid deposition, ground-level ozone, and particulate matter.
Detailed explanation-4: -Acid rain is a problem in eastern Canada because many of the water and soil systems in this region lack natural alkalinity-such as a lime base-and therefore cannot neutralize acid naturally.
