Under the Alberta and federal governments’ pipeline proposal, Trans Mountain will assume responsibility for the planning and construction of the pipeline from Bruderheim, Alta., to a proposed large-tanker port in Roberts Bank, B.C., just south of Vancouver, in hopes of expanding oil exports to Asia. Calgary-based Pembina Pipeline has so far agreed to take a minority 10 per cent private stake in the development, while the publicly owned Alberta Petroleum Marketing Commission is also a proponent.
