Notley called on the Trudeau government to fight the issue at the Supreme Court and recall Parliament to give what she called a "crisis" the attention it deserves. The sale will be finalized as early as Friday.
The ruling requires the energy board to conduct a new review including the impacts of tanker traffic and means the government will have to redo part of its consultation with Indigenous groups.
The Federation of Sovereign Indigenous Nations (FSIN) is celebrating alongside its counterparts in Squamish, B.C. after the Federal Court of Appeal overturned Ottawa's approval of the pipeline's expansion, citing a lack of proper consultation with Indigenous groups.
She has trouble understanding the lengthy appeals and court challenges that have dogged the project for nearly two years, calling them a waste of resources.
"Meaningful consultation is not intended simply to allow indigenous peoples "to blow off steam", the decision said".
Political scientist Duane Bratt said that while Notley can not be faulted for the court decision, it's still a political victory for Kenney.
The government intends to move forward to get the pipeline expansion built "in the right way", the prime minister said Friday, indicating that the government accepts the Federal Court of Appeal's criticism of the approval process.
Notley's government has budgeted for increased pipeline access to drive non-renewable resource revenue to more than double to $10.4 billion by 2024 to balance the books.
Trudeau approved the expansion, arguing that it was "economically necessary", and it enabled him to overcome opposition to a carbon tax plan that will help Canada cut its greenhouse emissions.
Meanwhile, Alberta Premier Rachel Notley vowed her province would withdraw from the federal climate plan until Ottawa gets its act together and pushes the controversial mega project ahead.
Notley said the province is still committed to its own climate change leadership plan despite the move away from the federal plan. The TMP carries oil from Edmonton to Burnaby, and the expansion would triple the capacity of oil exports.
As progress on the Trans Mountain pipeline stalls, Ottawa has lost another provincial ally in the climate fight - leaving the Trudeau government scrambling for answers as the crowd of friendly faces thins across the country. The project would have a serious impact unless design changes were made, such as altering shipping routes, reducing tanker speeds or the number of vessels, Tollefson said.
Many indigenous people see the 620 miles (1,000 kilometers) of new pipeline as a threat to their lands, echoing concerns raised by Native Americans about the Keystone XL project in the U.S. Many in Canada say it also raises broader environmental concerns by enabling increased development of the carbon-heavy oil sands. "The court has stepped in where Canada has failed to protect and respect our rights and our water".
"I've always said, if there are provinces that don't want to participate in this climate change plan, the federal government will do it alone".
