The move comes as Via Rail resumes normal service in Eastern Canada and its main cross-country line.

All routes across Canada affected by the Wet'suwet'en solidarity protests could be up and running again by next Friday, the company says.

Protesters set up a blockade Wednesday afternoon on the Mont-Saint-Hilaire line in Saint-Lambert, Que., in solidarity with Wet'suwet'en hereditary chiefs.

Via says it 'has no choice but to continue the cancellation of its services on a large part of its network' while rail lines in other parts of the country remain closed.

Meanwhile, Prime Minister Justin Trudeau told the House of Commons that finding a solution to the crisis "will not be simple."

Via Rail has reached a tentative contract agreement with Unifor, avoiding a work stoppage that could have begun as early as Monday morning.
