The protest along CN Rail tracks east of Belleville, Ont., has halted the company's eastern network — about one-quarter of its operations — and choked shipments from coast to coast.

The blockade was in solidarity with Wet’suwet’en Nation hereditary chiefs in British Columbia who are protesting the construction of the Coastal GasLink pipeline.

"The longer that this goes on, the more disastrous the effects on the economy."

During the early planning stages of the pipeline, the Wet'suwet'en hereditary chiefs proposed an alternate route, but Coastal Gaslink deemed it unacceptable.

London was included in three southwestern Ontario rail corridors that resumed service on Thursday.

Longueuil police served demonstrators protesting in support of the Wet’suwet’en with an injunction demanding they clear the tracks.

In August last year, the Ontario Court of Appeal ordered a fresh trial for the men on grounds the jury that convicted them was improperly chosen.

An internal letter to B.C. RCMP members obtained by Global News details plans to meet with the Wet'suwet'en hereditary chiefs and discuss removing a mobile detachment on their land.

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.

While the situation feels familiar, for many industries, the impacts are only adding to a pile of issues tangling the rail system.
