Federal government's approval of the Trans Mountain oil pipeline challenged in court.

New Update

The approval of Kinder Morgan's proposal of its Trans Mountain pipeline from Alberta to Burnaby, B.C. has sparked protests by climate change activists from coast to coast.

The ruling government gave a go to the $6.8-billion pipeline expansion late last month, despite a thicket of existing legal challenges to the regulatory process.

Conservation groups have filed a new court challenge to the federal government's approval which happens to be at least the eighth legal test of the project.

The groups argue that the impact of the project on endangered southern resident killer whales is not taken into consideration.
