Exchange Service

Needing 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 from one point on our system and receive/deliver an equal quantity of gas to an off system point of an upstream or downstream pipeline. This service is a great way to meet short term gas requirements outside of South-western Ontario without a long term transportation commitment with another pipeline upstream or downstream of Dawn.

  • Interruptible service 
    • Firm service may be available
  • Reliability of service is subject to pipeline scheduling at the Exchange location
  • Entering into a demand charge rate or paying a premium variable rate will improve IT reliability

  • Nomination changes at other NAESB windows are negotiable
