'This case is about more than a risky pipeline and tanker project; it is a major setback for reconciliation,' Tsleil-Waututh Chief Leah George-Wilson said.

The dismissal effectively ends a years-long legal battle over the Trans Mountain pipeline approval.

An estimated 150-190 cubic metres (150,000 to 190,000 litres) of sweet crude oil spilled from its Sumas Pump station early Saturday and the pipeline was shut down.

The pipeline remained shut down Sunday, amid cleanup operations after an oil spill at the Sumas Pump Station in Abbotsford.

While there is no threat to the community, the pipeline remains shut and an investigation into the cause of the spill is ongoing, Trans Mountain said.

Construction on a seven-kilometre section of the Trans Mountain pipeline has begun in Kamloops.

Work to lay 50 kilometres of pipe for the Trans Mountain pipeline expansion project is almost half complete in Greater Edmonton.

The Supreme Court of Canada has decided not to hear five challenges from environment and Indigenous groups from British Columbia.

Finance Minister Bill Morneau said up to 129 communities will be consulted to ensure they have a chance for "meaningful economic participation" in the Trans Mountain pipeline.

Trans Mountain now anticipates completing the project by 2022, with construction started on all parts of the line by the end of 2020.
