In 2005, Kinder Morgan bought the TransMountain Pipeline which runs from Edmonton, Alberta to Burnaby, British Columbia. They announced plans in 2011 to expand their capacity by building a parallel line. In 2012, they announced a further capacity expansion to a new total of 890,000 barrels of oil per day.
The original pipeline was built in 1953 without the benefit of public or environmental scrutiny and there was no public review when, in about 2006, it began shipping diluted bitumen (dilbit) as well as other crude and refined oils in the pipeline.
