One after another, Conservative MPs stood in the House of Commons Monday and urged the prime minister to call Montreal Mayor Denis Coderre and express support for the Energy East pipeline, which Coderre vowed last week to fight.

Interim leader Rona Ambrose led the charge, saying that Prime Minister Justin Trudeau 鈥渟hould stop using his cell phone for selfies with Leo DiCaprio and call Denis Coderre and fight for natural resources.鈥 Trudeau met with the Oscar-winning actor and environmental activist last week at the World Economic Forum in Davos, Switzerland.

鈥淭here鈥檚 almost 100,000 people out of work in (the natural resources) sector,鈥 said Ambrose. 鈥淒oes the prime minister understand that his lack of leadership on this issue is creating divisions in this country?鈥

Trudeau retorted that he found it strange the Conservatives were 鈥渃riticizing us for not getting done in 10 weeks what they were not able to do in 10 years,鈥 referring to the Tories鈥 track record on getting major pipelines built.

鈥淲e are working hard鈥︹ the prime minister went on, 鈥渢o make sure we鈥檙e creating the social license, the oversight, the environmental responsibility and the partnership with communities to get our resources to market in a responsible way because that鈥檚 what it takes in the 21st century.鈥

Conservative natural resources critic Candice Bergen echoed Ambrose, saying that when Coderre came out against Energy East, the prime minister 鈥渨as in Davos being star struck by actors.鈥 She implored him 鈥渢o pick up the phone, call the mayor of Montreal, tell him to smarten up and start standing up for Canadian jobs.鈥

Natural Resources Minister Jim Carr responded to another volley from Bergen, saying that he will 鈥渟tand up for jobs in Alberta and New Brunswick and Newfoundland,鈥 adding that 鈥渮ero鈥 major pipelines had been built under the Conservatives because 鈥渢heir process did not have the public confidence of Canadians.鈥

Bergen said that, in fact, 鈥渇our major pipelines鈥 were built during their tenure.

Quebec MP Gerard Deltell also demanded Trudeau phone Coderre, saying that the Energy East project will create about 3,000 jobs in Quebec.

Saskatchewan MP Andrew Scheer followed, calling Energy East a 鈥渟hovel-ready massive stimulus project鈥 that 鈥渨on鈥檛 cost taxpayers a cent,鈥 and demanded that the prime minister 鈥渄enounce Coderre.鈥

Ambrose later told CTV鈥檚 Power Play that she has heard Trudeau will call Coderre, adding she hopes he will ask the mayor to 鈥渉ave an open mind.鈥

鈥淚 would encourage him to be open to the suffering of thousands of people in western Canada who have always been generous to the country,鈥 Ambrose said.

鈥淎lbertans have paid billions into equalization over the years,鈥 Ambrose went on. 鈥淭hey鈥檝e never complained.鈥

鈥淭hey鈥檙e very generously happy to do that, to support the federation, but when they鈥檙e suffering they feel maybe that parts of the country are turning their backs on them,鈥 she added.

Earlier in the day, Ambrose said Coderre 鈥渋nsulted鈥 Albertans when he came out in opposition to TransCanada鈥檚 Energy East.

The project involves converting an existing pipeline from northern Alberta to Montreal, and then building a new portion of pipeline east from there to a refinery New Brunswick where it could be shipped to other parts of eastern Canada and other countries.

On Thursday, Coderre said that he and other mayors representing 82 municipalities in the Montreal area will fight the Energy East pipeline because the economic benefits for Quebec would be small compared to the possible clean-up costs of a spill.

鈥淎t the end of the day, it鈥檚 all about our territory,鈥 Coderre said last week.

Ambrose invited Coderre and other Montreal-area mayors opposed to the project to visit Alberta to get a first-hand look at the province鈥檚 environmental record and the technology used to 鈥渟afely鈥 build pipelines.

鈥淵es, oil prices have plummeted, but the key to long-term growth for the energy sector across the board is pipelines,鈥 Ambrose told reporters.

鈥淔or Mr. Coderre to come out and insult Albertans and oppose a pipeline that hasn鈥檛 even been built yet is unfortunate,鈥 she said. 鈥淭his isn鈥檛 in the spirit of Confederation.鈥

Ambrose said she would like Coderre and other Quebec mayors to look at the pipeline issue 鈥渇rom an evidence-based, fact-based, science-based鈥 angle -- 鈥渘ot from pure local politics.鈥

Other politicians, including Alberta Premier Rachel Notley, Calgary Mayor Naheed Nenshi and Saskatchewan Premier Brad Wall, slammed Coderre for his stance.

Nenshi argued on CTV鈥檚 Power Play last week that the pipeline is a good project because it will allow eastern Canadians to substitute energy sourced from countries like Saudi Arabia and Venezuela with energy from western Canada.

Nenshi also said pipelines are safer than transporting oil by rail, pointing to the tragic 2013 accident that killed 47 in Lac-Megantic, Que.

The NDP, which has expressed support for Energy East conditional on a stronger environmental review process, chastised the Liberals in question period Monday for continuing the review process for Energy East, and a pipeline proposal from Kinder Morgan, using what Energy and Natural Resources Critic Peter Juilan called 鈥渢he Conservatives鈥 broken rules.鈥

Minister Carr responded that, 鈥渢here will be a transitional process that will govern those major projects that are currently under review,鈥 adding 鈥渢hat process will embody the principles that will be necessary if we are going to get approval of these very important projects for Alberta, Saskatchewan, New Brunswick and Newfoundland.鈥

NDP Leader Tom Mulcair later told Power Play the Liberals are 鈥渂acking away from a very clear promise鈥 made during the election for a new process that would considering things like climate change when deciding on approvals for Kinder Morgan and Energy East.
