The Canada Pension Plan Investment Board (CPPIB) Chief Executive Officer, Mark Machin said, “Greenhill & Co., Inc. (NYSE:GHL) has been hired by Ottawa to manage the purchase and sale of Kinder Morgan Canada Limited (TSX:KML)'s Trans Mountain pipeline, recently reached out to institutional investors that could potentially be interested in the project”. Mark Machin told MPs on June 11, 2018 that no decisions have been made as to whether CPPIB would be interested in buying the pipeline. "We're still evaluating the situation", Mark Machin said when asked by Conservative MP Tom Kmiec whether the board would consider investing in Trans Mountain.

"We obviously have an obligation to assess every major investment opportunity that comes along and fully understand the risks, fully understand the potential returns and understand how it might fit into our portfolio". When asked directly, Mark Machin said there have been no conversations between federal government officials and CPPIB executives related to the Trans Mountain pipeline. "What I can say is that Greenhill, which is the financial adviser to the federal government, has approached us", he said.
