The RCMP said it has discretion to decide how and when to enforce the Injunction Order and Mounties are monitoring the situation and take action a case-by-case basis.

Observers say the start of construction on the Minnesota portion of the Enbridge Line 3 replacement pipeline after six years of delays has lifted spirits.

Work on the Trans Mountain pipeline has been suspended until early January after a worker in B.C. was injured this week and an Edmonton worker was killed in October.

Trans Mountain did not elaborate on the nature of the incident or what injuries were suffered, other than to say the worker is in stable condition in hospital.

Protesters gathered at the intersection of North Road and Trans-Canada Highway.

Three days after a worker was pinned by a piece of equipment and died at pipeline work site in west Edmonton, the Canada Energy Regulator has issued a number of directives to Trans Mountain Corp.

Husband and father Samatar Sahal, 40, was killed while working at a Trans Mountain pipeline site in west Edmonton on Tuesday.

The project is advancing as expected despite challenges including the COVID-19 pandemic, a global slump in demand for fuel, a $5.2-billion rise in its estimated cost to $12.6 billion in February and ongoing protests by opponents, said CEO Ian Anderson in an interview.

'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.
