Parliament's spending watchdog says a series of rail blockades last month will leave a minimal dent in the pace of economic growth.

Hereditary chiefs and the BC Civil Liberties Association say B.C.'s public safety minister green lit the extra officers in a letter to the RCMP.

Commuter train service on the Candiac line between Montreal and the south shore will resume on Friday afternoon after the dismantlement of a rail barricade in Kahnawake on Thursday.

In the last month, Indigenous people across the country set up barricades on train tracks, roads and bridges, in solidarity with Wet'suwet'en Nation hereditary chiefs, some of whom object to the construction of a natural-gas pipeline through their traditional territory.

The hereditary chiefs and spokespeople have asked for continued support and solidarity so we’re continuing that.

The hereditary house chiefs reached a draft agreement Sunday with senior federal and provincial government ministers centering on rights and title. Crown-Indigenous Relations Minister Carolyn Bennett said it would be signed if the Wet'suwet'en Nation reaches a consensus on it.

Work is expected to resume today on a natural gas pipeline in British Columbia that has been at the centre of protests that have disrupted both rail and road traffic in many parts of the country.

Peter Grant spent 10 years representing the Wet'suwet'en in the Delgamuukw case left dangling by the Supreme Court in 1997, which could be resolved by the proposed agreement announced Sunday.

The chiefs reached the agreement late Saturday night with federal Crown-Indigenous Relations Minister Carolyn Bennett and her B.C. counterpart Scott Fraser.

When Prime Minister Justin Trudeau stepped in front of cameras last week to declare that barricades on rail lines and other major transportation routes had to come down, the move had been decided almost two days before.
