Nebraska regulators gave TransCanada’s Keystone XL the green light Monday morning in a razor-thin, 3-2 vote. Experts weighed in on the decision that was a crucial hurdle for the project.

Here’s some of what they told BNN:

“As a Canadian, I’m very hopeful because of the huge contribution that this project would make to producers in western Canada, to tax dollars, to jobs, to royalty revenue for governments – a very important project go-ahead. Hopefully there will be enough commitment there to make it work.”

- Patrick Daniel, former CEO, Enbridge 

TransCanada has been 'amazingly patient' and deserves to have Keystone XL built: Former Enbridge CEO

Whether it's through tax dollars, more jobs, or royalties to the government, former Enbridge CEO Patrick Daniel says the Keystone XL approval decision will be great for Canada's economy.

“No doubt, the opponents will throw the legal kitchen sink, so to speak, at this project. ”

- Dennis McConaghy, former executive vice-president of pipeline strategy and development, TransCanada

Keystone architect says Nebraska decision a key milestone

Former TransCanada executive Dennis McConaghy, who oversaw the Keystone XL pipeline plan, says Nebraska approval of the pipeline's route removes a major roadblock for the giant project.

“This is not the optimal pipeline to build. This pipeline is moving to the U.S. markets. And what we need more than anything – if we really want to achieve maximum profitability – we need to get more of our products to the global markets. And that means coastal pipelines like Trans Mountain.”

Keystone XL is not the optimal pipeline to build: Money manager

We hear from Rafi Tahmazian, senior portfolio manager with Canoe Financial, who says KXL is not the optimal pipeline to build and that Canada still needs the Trans Mountain pipeline.

“I think, unfortunately, this could be headed to the Supreme Court.”

“The oil has to move somehow. Look, a spill of some oil in a farmer’s field in South Dakota is better than blowing up a town in Quebec. We view pipelines as being very much safer than oil by rail and much cheaper as well.”
