The pipeline would bring oil from the Alberta oilsands to BC's north coast, to be transported to Asia via supertankers. This would require lifting the longstanding oil tanker moratorium and Tanker Exclusion Zone.

The pipeline would cross 800 streams and rivers, as well as other sensitive ecosystems and numerous First Nations communities. The risk of major oil spills, whether on the pipeline route or on the coast, is potentially catastrophic and could take decades to recover from.
