Proposed Expansion

Trans Mountain is proposing an expansion of its current 1,150-kilometre pipeline between Strathcona County (near Edmonton), Alberta and Burnaby, BC. The proposed expansion, if approved, would create a twinned pipeline that would increase the nominal capacity of the system from 300,000 barrels per day, to 890,000 barrels per day.
