CALGARY, ALBERTA--(Marketwired - Nov 15, 2016) - Media Advisory - TransCanada Corporation (TSX:TRP) (NYSE:TRP) (TransCanada) today announced it will not proceed at this time with its new, long-term, fixed-price proposal to flow natural gas along the Canadian Mainline from the Empress receipt point in Alberta to the Dawn hub in Southern Ontario.

"The Open Season for the proposed service resulted in bids that fell well short of the volumes required to make the proposal viable," said Stephen Clark, TransCanada's senior vice president and general manager, Canadian Natural Gas Pipelines.

"The Canadian Mainline system continues to be commercially supported and an important piece of energy infrastructure that connects the country's most prolific supply basin with North America's highest value markets," concluded Clark.

With more than 65 years' experience, TransCanada is a leader in the responsible development and reliable operation of North American energy infrastructure including natural gas and liquids pipelines, power generation and gas storage facilities.
