Kinder Morgan is seeking to raise about $1.75 billion in an initial public offering of assets including the Trans Mountain pipeline system in Canada, scrapping plans for a sale to potential partners such as ArcLight Capital Partners.

The pipeline operator plans to offer the shares in Kinder Morgan Canada at between $19 and $22 apiece and list in Toronto, according to a regulatory filing Wednesday.

Houston-based Kinder Morgan was running a dual track process, exploring both a minority stake sale of the assets along with a potential IPO. It said in a regulatory filing it was no longer exploring the joint venture.

“KMI believes that the offering represents the superior path for financing the project for several reasons, including favourable governance, more certainty around timing, and a greater retained interest by KMI,” the company said, adding that it expected the offering to be completed by the end of May.

Kinder Morgan’s planned expansion of the Trans Mountain pipeline may face more opposition after the ruling Liberal Party in British Columbia was reduced to a minority government in elections Tuesday. They may now have to rely on support from the opposition Green Party, whose leader Andrew Weaver has said Kinder Morgan’s pipeline has “no place on our coast.”

The pipeline project has already won approval from the B.C. and federal governments.

Kinder Morgan is expected to retain as much as 77 per cent of Kinder Morgan Canada if the share sale were to proceed, the filing shows. Toronto-Dominion Bank and Royal Bank of Canada are leading the share sale.

U.S. private equity firm ArcLight Capital Partners was among final bidders to partner with Kinder Morgan in a joint venture of its C$7.4 billion Trans Mountain Expansion Project, people familiar with the matter have said. Brookfield Asset Management and Australia’s IFM Investors also progressed to the late rounds, the people said.
