Canada’s main stock index capped a good week with the energy sector closing higher Friday as investors responded positively to federal action to kick-start construction of the Trans Mountain pipeline expansion.

Ottawa ordered the National Energy Board to redo its environmental review of the controversial project, this time taking into account the impact of additional oil tanker traffic off the coast of British Columbia.

The move came less than a month after The Federal Court of Appeal quashed the approval the NEB and the cabinet gave the project in 2016, citing improper consultation with Indigenous communities and a lack of review of the marine shipping issue.

“Any sort of movement on pipelines is viewed to be somewhat positive so we’re seeing a little boost on that side,” said Jamie Robertson, senior portfolio manager at Manulife Asset Management.

“It just feels like some of the tension around trade and tariffs has quieted down a little bit so the market is cheering that a little bit,” Robertson said in an interview

Tilray Inc. closed down 30.25% to US$123 on the Nasdaq, two days after it went on a wild ride by surging more than 90%, dropping into negative territory and rebounding after the licensed producer said it got approval to export medical cannabis from Canada to the U.S. for a clinical trial.
