Energy East would have carried 1.1-million barrels of crude oil a day from Alberta to Saint John, New Brunswick.
It will now inform the federal and provincial regulators that it will no longer be proceeding with its applications for the projects.
"We will continue to focus on our $24 billion near-term capital program which is expected to generate growth in earnings and cash flow to support an expected annual dividend growth rate at the upper end of an eight to 10 per cent range through 2020", Girling said. While the coalition treated Thursday's news as a victory, Picard said there remains three more pipelines to defeat: Kinder Morgan's Trans Mountain expansion, TransCanada's Keystone XL pipeline, and Enbridge's Line 3 project.
The company TransCanada had asked the national energy Board (NEB) last month to suspend the process of approval of the pipeline, after the criteria had been tightened.
In a press release Thursday, the company - which is also behind the controversial Keystone XL project - said the decision to cancel the Energy East project, a tar sands pipeline to New Brunswick, and the Eastern Mainline project, a natural gas pipeline along the northern side of Lake Ontario, came "after careful review of changed circumstances".
"But there is no doubt that with the Energy East pipeline project we would have been able to do even more to grow the economy, strengthen education and improve health care in our province".
While Energy East's collapse may cost Trudeau support in the traditionally conservative oil heartland of Alberta it is likely to prove popular in the eastern province of Quebec, which has far more parliamentary seats and where pipeline opposition from politicians and environmental groups had been stiff.
"This is an unfortunate outcome for Canadians", said Notley in a statement. The company says the filing with the National Energy Board makes almost 700 changes to the route in response to concerns for environmentally sensitive areas.
TransCanada will also notify Quebec's Ministère du Developpement durable, de l'Environnement, et Lutte contre les changements climatiques that it is withdrawing the Energy East project from the environmental review process.
"The emissions associated with new pipelines are inconsistent with our climate imperative and the threat to waterways, wildlife, and lands was enormous".
February 3, 2016: The National Energy Board directing TransCanada to rework its application to build the contentious Energy East pipeline because the document is too hard to understand - even for experts. It was first proposed in 2013. These pipelines are bad for the climate, bad for communities, and bad for business.
"This was an investor decision that resulted from the low global price of oil. Governments need to step up with a plan to assist oil sands workers in transitioning into clean energy jobs".
