Trans Mountain Pipeline Protesters March 75 Km. To Burnaby, B.C.

Kinder Morgan said the company received the necessary approvals from the government.

BURNABY, B.C. — Hundreds of people in British Columbia have completed a 75-kilometre march in protest of the Kinder Morgan Trans Mountain pipeline expansion.

The four-day trek called Walk For the Salish Sea ended with a rally in Burnaby, B.C., Sunday afternoon with speeches scheduled from federal Green Party Leader Elizabeth May, Burnaby Mayor Derek Corrigan and Grand Chief Stewart Phillip.

Texas-based Kinder Morgan recently gave a conditional financial go-ahead for the expansion, which would triple the amount of Alberta oil that flows to B.C.'s coast and increase tanker traffic by seven-fold.

Rally organizer Joel Ornoy says the pipeline poses a serious risk for the environment, nearby residents and economy if a spill were to occur.

In addition to putting a spotlight on the issue, Ornoy says the march raised thousands of dollars for indigenous groups fighting the pipeline proposal in the courts.

But Simon Fraser University English professor Stephen Collis, who took part in the rally, said the pipeline is not a done-deal.

"There is still a lack of indigenous consent and there's a lack of public consent and this event is about showing that people are still concerned and still opposed and still intending to make sure this does not happen," he said.

"Many, many (First) Nations whose territories the pipeline will cross are vocally opposed to this."

Collis added that past litigation, including a landmark 2014 Supreme Court of Canada case that favoured the Tsilhqot'in people in B.C. in a battle over land title, sets a precedent for ongoing legal battles related to the area the Trans Mountain pipeline will cross.

"Many, many (First) Nations whose territories the pipeline will cross are vocally opposed to this," he said. 

Collis said it's just a matter of getting their cases through the courts.
