The association says the 14 per cent increase in its members' spending intentions to about $27.3 billion this year compares with total investment of about $24 billion in 2020.

Teck Resources is leaving the Canadian Association of Petroleum Producers, an industry organization whose members represent about 80 per cent of Canada's oil and gas production.

The first increase was on Jan. 30 when Notley announced the province would allow increased production by 75,000 barrels per day.

Notley has said she is concerned the changes would impinge on a provincial right to manage resources.

The man behind the account, Brian Baron, said he posted the tweet as a way to create a discussion and was trying to be more humorous than anything else. He said he didn't find Nenshi's comment particularly offensive.

Cenovus Energy Inc. says it is cutting oilsands production, putting more barrels in storage, ramping up rail shipments and may delay producing from a nearly completed expansion project to avoid current steep price discounts.

The Canadian oil and gas sector is in a holding pattern in which spending and production growth can't occur until new ways to get products to export markets are found, according to CIBC analyst Jon Morrison.

Thursday's court ruling prompted Alberta Premier Rachel Notley to announce that her province is withdrawing from the national climate change plan and will stay out until the federal government gets its act together, as she put it.

"This kind of delay in terms of getting a pipeline built means we are selling oil at prices that are very discounted from what we should be getting."

First Nations, including the Tsleil-Waututh and Squamish on British Columbia's south coast, argued the federal government did not adequately consult them before the energy board review or the cabinet decision to approve the project.
