5 things to know about the Trans Mountain pipeline battle

Kinder Morgan has set the stage for two months of high drama.

The company announced it is suspending non-essential activitiesand related spending for the Trans Mountain pipeline expansion, casting acloud over the future of the $7.4-billion project.

• Kinder Morgan 'open to' Alberta investing in pipeline
• Notley demands 'concrete action' from Ottawa to get Trans Mountain pipeline moving

It said it would still try to get agreements that would see the project advance, but would need to do so by May 31 or "it is difficult to conceive of any scenario in which we would proceed."

The news quickly spurred the leaders of the Alberta, British Columbia and federal governments to issue statements of resolve, positioning themselves for a tense few weeks.

Opponents of the pipeline must also feel victory within their grasp.

So with billions of dollars of developmentand political fortunes at risk, here are five things to know from Sunday's announcement on Trans Mountain.

Kinder Morgan wants less risk

It hasbecome a bit of a clichin these days of Brexit and Donald Trump to say that the market hatespolitical uncertainty but it doesn't mean that it isn't true.

It seems Kinder Morgan's biggest concern with the Trans Mountain pipeline is the political risk posed by B.C. and its legal challenges to it.

"While we are prepared to accept the many risks traditionally presented by large construction projects, extraordinary political risks that are completely outside of our control and that could prevent completion of the project are risks to which we simply cannot expose our shareholders,"SteveKean, CEO of Kinder Morgan Canada, saidin a statement.

What Kean wants is agreements by May 31 that remove any undue risk. Simply put, he wants "clarity on the path forward," particularly the ability to construct through B.C. and adequate protection of itsshareholders.

Those seem like big goals and even the company acknowledges the time period is short.

Alberta willing to buy in

Premier Rachel Notleyannounced during her news conference on Sunday that the Alberta government was prepared to do whatever it takes to get the pipeline built.

That "whatever" might mean Alberta becoming an investor in the pipeline.

"If we take that step, we will be a significantly more determined investor," Notleytold reporters."This pipeline will be built."

Her comments perhaps demonstrate just how badly the province needs the pipeline.Her government's path to balanced budgets is built on hopes for construction of three new pipelines, including Trans Mountain.

But even one of Notley's fiercest critics, Alberta United Conservative Party Leader Jason Kenney,backed the idea.

"I believe the government of Alberta must be prepared, along with the federal government, to step up and provide financial certainty to the investors of Kinder Morgan," said Kenney.

'Serious economic consequences' ahead?

Notleyonce hit B.C. with a wine ban over Trans Mountain. Now, the premier is warning of more.

She saidthe Alberta government is bringing forward legislation in the coming days that would give it the power to impose "serious economic consequences on B.C." if its leadership didn't change course.

"Premier [John] Horgan believes he can harass this project without economic consequences for his province. He is wrong."

Notleyhas already said her government will refine and update existing legislation that gives Alberta the ability to limit oil and gas exports, indicating it could stem the flow to B.C.

Asked if Alberta might proceed with another wine ban or something else in the coming days, Notley would only say there are other tools the government is looking at.

B.C. wants less risk, too

On Sunday, B.C. Premier John Horgansounded much as he has throughout the Trans Mountain debate, stating the concerns his government hasabout protecting the environment and disagreeing with the notion that the pipeline is in the national interest.

Furthermore, he rejected the notion that the project had been unnecessarily harassed by B.C.

"My views on this have been consistent for the past year," said Horgan."We believe the risk is too great and there is no evidence to indicate that that risk has been diminished."

Horgan is pursuing a reference case in the courts to determine if his government can control the shipment of oil through the province on environmental grounds.

"I profoundly believe in the rights of British Columbians to stand up and make sure that we're doing everything we can to protect the interests of our province," he said.

"I don't want to do that in a provocative way. I don't want any threats. I don't want any ultimatums."

What will Ottawa do?

What is Prime Minister Justin Trudeau's next move? That's a big question and there's a lot riding on the answer, whether you're a pipeline supporter or opponent.

Notley is now calling on the government to go from using "carrots" to maybe a "stick" to get the pipeline to move ahead.

Alex Pourbaix, CEO of Cenovus Energy, also called on the federal government to take "immediate, clear and decisive action" to ensure that the project does not suffer the same fate as the Energy East project.

"If the rule of law is not upheld and this project is allowed to fail, it will have a chilling effect on investment not just in British Columbia, but across the whole country," he said in a statement.

Trudeauwas in Saskatchewan on Sunday for a vigil for the Humboldt Broncosfollowing Friday's fatal bus crash. But in regards to the pipeline issue, he said on social media that "Canada is a country of the rule of law, and the federal government will act in the national interest."

He also added once again thatthe pipeline expansion "will be built."

However, what steps he's prepared to take still seemunclear.
