Tensions continue to rise surrounding the stalled Trans Mountain pipeline expansion. Kinder Morgan’s 7.4-billion-dollar project, which aims to triple the bitumen flowing from Alberta to B-C’s coast for export, was the subject of an emergency House of Commons debate Monday night. B-C New Democrat M-P Nathan Cullen echoed the B-C government’s concern about the environmental impact any potential spill could have on a Vancouver-area port and the coastline with a seven-fold increase in tanker traffic. The Commons debate was called after tensions began escalating among the provinces hours earlier. B-C’s attorney general threatened to sue Alberta over legislation it has now introduced to restrict the flow of oil, gasoline and natural gas leaving that province, which could boost fuel prices in B-C.
