Two members of Parliament have been arrested for violating a court order to remain away from Kinder Morgan's Trans Mountain Pipeline Expansion project.

Green Party of Canada Leader Elizabeth May and Burnaby South NDP MP Kennedy Stewart were standing at the gates of the company's Burnaby facility when they were taken into custody earlier today.

After May was released, she told reporters that she has been charged with civil contempt for blocking the road.

"I have never before put my signature on a line that said signature of accused," May said. "But my rights have been read to me and I will return to court June 14."

May said that she will abide by the terms of her release but will also continue to speak out against the pipeline project.

Stewart wrote on his Facebook page that Canadians have a constitutional right to peaceful protest, "especially when governments abuse power".

"During the last election, Justin Trudeau said that 'while governments grant permits... only communities can grant permission.' I am here today to help amplify the voices of my constituents who do not grant permission for this pipeline," he stated.

"The process by which the Trudeau government approved Kinder Morgan's plans to build a dangerous new pipeline through our community without our consent was deeply flawed and unfair," Stewart declared on his Facebook page. "The Prime Minister broke his promise to revise the National Energy Board pipeline review process and require Kinder Morgan to resubmit its plans under this new process. His government has also threatened to use military force to facilitate construction."

"First Nations' and municipal governments as well as the Province deeply oppose this pipeline as British Columbians take most of the risk for little benefit," the NDP MP continued. "I feel it is my responsibility to do whatever I can to advocate for my community as its elected Member of Parliament, including exercising my constitutional rights."

The Kinder Morgan project will triple diluted bitumen shipments from Alberta to the company's Burnaby tank farm, which is being expanded.

The project will also result in a nearly seven-fold increase in oil-tanker traffic in Burrard Inlet.
