The pipeline expansion to the West Coast has been approved by the federal government, but B.C.is fighting it in the courts.
Horgan has said that he will continue to challenge Alberta in court over the pipeline and B.C. Attorney General David Eby said that he will take Alberta to court over Bill 12 if gas prices in the western province jump significantly.
The company, which earlier this month suspended work on its expansion of the Trans Mountain pipeline, moved 289,000 barrels per day (bbl/d) of crude and refined products through the pipeline down from 307,000 (bbl/d) a year earlier.
Protests remain loud and strong, and tanker spills are still a big worry, but a new poll finds a slim majority of British Columbians now support the Trans Mountain pipeline expansion.
The pipeline emerged at the centre of a national debate this month after Kinder Morgan issued what many critics of the project viewed as an ultimatum to the Canadian government. If Albertans want to buy themselves a pipeline that may or may not be built, that's up to them. The campaigners say that while Trudeau may be using his European trip to tout his country's "ambitions for fighting climate change", his continued insistence that the pipeline "will be built" proves that his supposed support for the climate rings hollow.
Horgan said that B.C. will "abide" by the court's decision.
"This crucial resource project will expand export markets for Canadian resources and create thousands of good, middle-class jobs and no one should be standing in the way of those jobs and the families that stand to benefit", Carr said in a statement.
The situation escalated further Monday as Saskatchewan Premier Scott Moe indicated he will follow Alberta's lead and provide for similar measures to restrict fuel shipments to B.C.
The battle has pitted environmentalists, some B.C city mayors, some aboriginal groups and the B.C government against Kinder Morgan, some aboriginal groups, the Alberta government and recently the federal government.
"Clearly the legislation is a bluff", Eby said Tuesday.
Calendinobrought up the idea of the pipeline being "the saviour of the economy", and asked why the federal government isn't financially backing housing or veterans instead.
Without the added pipeline capacity of Trans Mountain, the tool allows Alberta to send refined fuel to B.C.by rail.
Opponents of the Kinder Morgan project are concerned over the environmental impact of extracting more fossil fuels from Alberta's oil sands and the possibility of an oil tanker spill in Canada's Pacific waters.
"Despite the fact the premier is taking a very combative attitude, I'm not going to embargo Burnaby (products) from going back to Alberta, but it is a reality that this so-called trade war does nothing for Canadian unity", he said.
The company warned Sunday it may abandon the expansion unless an agreement is reached by May 31 to restore shareholder faith.
