All eyes are on Canadian police forces now that Prime Minister Justin Trudeau has said barricades on rail lines and other major transportation routes must come down.

A Wet'suwet'en hereditary chief says that won't happen unless and until the Mounties get off their traditional territory in northern British Columbia and Coast GasLink halts construction on a natural-gas pipeline that crosses their land.

Chief Woos of the Grizzly House says Indigenous leadership will only begin negotiating with the Canadian government under those same conditions. But Trudeau says injunctions ordering the rail lines be cleared must be obeyed and the law must be enforced.

The blockades are responses by Indigenous people and supporters to a move by the RCMP to clear protesters who had been blocking access to the pipeline worksite.

Protesters who'd been blockading a CN Rail line in St-Lambert, Que., south of Montreal since Wednesday cleared out Friday night shortly after riot police arrived on scene ready to enforce an injunction to clear the tracks. But the blockade of a critical east-west rail line on Tyendinaga Mohawk Territory in eastern Ontario remains in place -- and more protests are planned for March 20 along the borders of Manitoba.

Ontario Provincial Police say they don't intend to break up the Tyendinaga protest in the immediate future, however, Trudeau says the inconvenience to Canadians has gone on long enough, given that the blockades have halted rail lines for weeks.
