Where is Acid Rain a Problem in Canada?

     Acid rain is a serious environmental problem in Eastern Canada. This is due to the fact that many of the water and soil systems in this region have a deficiency in natural alkalinity and as a result is unable to neutralize acids naturally. The majority of Canada consists of unprotected hard rock that doesn’t possess the ability to neutralize acid rain. Provinces mainly affected are those in the Precambrian Shield such as Ontario, New Brunswick, Quebec, and Nova Scotia.

     Although the greatest impact of acid rain is found in Eastern Canada, Western Canada is also developing problems with acid rain. Lakes and soils resting on granite bedrock of the Canadian Shield, including Alberta, Northern Saskatchewan, Manitoba, parts of Western British Columbia, Nunavut and Northwest Territories, cannot neutralize precipitation. The impact in these areas could soon rise to be equivalent to those found in Eastern Canada if sulfur dioxide and nitrogen oxide emissions continue to increase
