Exchange Service

Looking to move gas into or out of Ontario?  Are you trying to take advantage of basis differentials?

Our exchange service allows you to receive/deliver gas at one point on our system, and receive/deliver an equal quantity of gas at an off system point. This service is a great way to meet short term gas requirements outside of Southwestern Ontario without a long term transportation commitment with pipelines upstream or downstream of Dawn.
