Following the suspension of the $7.4 billion pipeline project, Steve Kean, the CEO of Kinder Morgan, has expressed concern with the  viability of the expansion should his company remain committed to the project.

"It's become clear that this particular investment may be untenable for a private party to undertake," said Kean in a telephone conference conducted Wednesday. "We've pointed out there are significant differences between governments, and those differences are outside of our ability to resolve."

Pressure is mounting on the federal and provincial government after Kean's comments surfaced.

Premier Rachel Notley is aware of calls to fund the project with public dollars but says negotiations will continue with those already at the table.

UCP leader Jason Kenney questions the optimism of Alberta's premier following her meeting with Prime Minister Trudeau and B.C. Premier John Horgan.

An Angus Reid poll conducted in February 2018 found 48 per cent of British Columbia supported the project while 40 per cent were against the pipeline expansion. The organization has since found that 54 per cent of British Columbia residents now support Trans Mountain and that number would balloon to nearly 70 per cent  if it's determined their province does not have the constitutional right to block the project.
