OTTAWA -- RCMP began enforcing an injunction earlier this month that prevents interference with construction of a $6.6-billion natural gas pipeline in northern British Columbia.

Here is a timeline of the dispute, along with rail disruptions by people showing solidarity with the hereditary Wet'suwet'en chiefs opposing the Coastal GasLink project:

Dec. 31, 2019 - The B.C. Supreme Court grants Coastal GasLink an injunction calling for the removal of any obstructions including cabins and gates on any roads, bridges or work sites the company has been authorized to use.

Jan. 1, 2020 - The Wet'suwet'en First Nation serves Coastal GasLink with an eviction notice, telling the company workers are “currently trespassing” on their unceded territory.

Jan. 27 - The British Columbia government appoints former New Democrat MP Nathan Cullen as a provincial liaison with Wet'suwet'en hereditary chiefs in the LNG pipeline dispute.

Jan. 30 - The hereditary chiefs of the Wet'suwet'en agree to seven days of meetings with the province.

Feb. 5 - The talks that were intended to de-escalate the dispute fail after just two days.

Feb. 6 - The RCMP move in to Wet'suwet'en territory to enforce the court injunction that would have allowed construction work to resume. A handful of pipeline opponents are arrested. Hours later, outside of Belleville, Ont., east of Toronto, protesters start holding up railway traffic in solidarity with the Wet'suwet'en hereditary chiefs.

Feb. 7 - Via Rail halts service along one of its busiest routes because of the Belleville-area blockade. All travel between Toronto, Ottawa and Montreal is cancelled. Canadian National Railway obtains a court injunction to end a demonstration by members of the Tyendinaga Mohawk Territory near Belleville. Protesters also begin disruptions at ports in Vancouver and Delta, B.C.

Feb. 8 - Protesters in Toronto disrupt Canadian Pacific Railway traffic moving through the downtown area.

Feb. 9 - Kahnawake Mohawk community members south of Montreal erect a blockade on a CP rail line.

Feb. 10 - Demonstrators in the Montreal area disrupt commuter train service on the Exo Candiac line. A shuttle bus service is in effect for affected rail stations.

Feb. 11 - CN stops transport between Prince George, B.C., and Prince Rupert, B.C., because of a blockade near Hazelton, B.C. The company says it has halted more than 150 freight trains since blockades started on Feb. 6.

Feb. 12 - The Manitoba government says it may seek a court injunction to end a blockade on a rail line west of Winnipeg, but CN obtains its own court order. Two hereditary Wet'suwet'en chiefs start a constitutional challenge of fossil fuel projects, as Prime Minister Justin Trudeau calls for demonstrators across the country to observe the rule of law.

Feb. 13 - CN shuts down its operations in Eastern Canada. The railway says blockades have ended in Manitoba and may come down soon in British Columbia, but the orders of a court in Ontario have yet to be enforced and continue to be ignored.

Feb. 14 - A rail blockade that halted train traffic to and from the Port of Prince Rupert is lifted as First Nations leaders agree to meet with federal and provincial politicians.

Feb. 15 - Federal Indigenous Services Minister Marc Miller travels to meet with protesters in Tyendinaga Mohawk Territory near the site of the Belleville blockade. He says “modest progress” was made during nine hours of talks, but declines to share details on what was discussed.

Feb. 16 - Trudeau cancels his planned trip to Barbados, less than 24 hours before his scheduled departure, so he can handle the protests in Canada. Meanwhile, protesters briefly shut down a busy Ontario border crossing.

Feb. 17 - Trudeau convenes the Incident Response Group, an emergency committee that meets in the event of a national crisis.

Feb. 18 - An emergency debate is held in the House of Commons, where the Opposition Conservatives advocate for forceful action and the governing Liberals push for ongoing dialog with backing from other political parties. Meanwhile, CN issues temporary layoff notices for 450 employees, citing the ongoing protests as the reason for the move.

Feb. 19 - Protesters erect a blockade along a stretch of CN rail line in Edmonton, but are soon faced with counter-protesters who begin forcibly dismantling the barricade. The blockade is taken down later in the day. Via Rail announces nearly 1,000 temporary layoffs in light of ongoing service suspensions across much of Canada. The rail provider also cancels plans to resume a route between Ottawa and Quebec City as a new blockade is erected near Montreal.

Feb. 20 - Federal Public Safety Minister Bill Blair says the RCMP has offered to move its officers from Wet'suwet'en territory to a nearby town. He says this concession meets a key condition from the hereditary chiefs and calls for all rail blockades to be dismantled. Wet'suwet'en hereditary chiefs travel to Quebec and Ontario to thank supporters who have maintained the blockades.
