TransCanada Corporation is proposing a 1.1 million barrel per day pipeline from Alberta to New Brunswick that threatens to contaminate hundreds of watersheds along its 4,600-kilometre route, including both the Lake Nipissing and Trout Lake watersheds in Northern Ontario. The Energy East project is the largest tar sands pipeline proposed yet and would be larger than any existing pipeline in Canada. The proposal seeks to convert an existing, up to 40-year-old natural gas pipeline from Saskatchewan to Ontario. New pipeline would be added in Eastern Ontario, travelling through Quebec to a new major export port in Saint John, New Brunswick.
This briefing paper shows how the pipeline route puts watersheds at risk, provides a realistic estimate of the likelihood of a pipeline rupture, and uses modelling to determine the potential costs of an oil spill in the North Bay area.
