New name for Unionline, same trusted experience

Starting at 9:30 p.m. on May 26 until 4 a.m. on May 27, Unionline will be unavailable. Why? Because our Enbridge Gas team will be hard at work giving the application its new Enbridge Gas identity - its new name of Enerline.

Why change a good thing? Well, that’s the good news. All of what you love about working within Unionline is staying the same. The way you navigate, the way you conduct business within the application, how you view the information – none of that has changed.

All we are doing is bringing Unionline into the Enbridge Gas brand family. That’s it!

What are we changing (besides the name)?

  • With a new name, comes a new URL: 
  • Updated colour schematics to align with its Enbridge Gas identity
  • A new email address for our Enerline Support team:

Would you like a sneak peek into Enerline? Check out this short video.

How can we help?

Enbridge Gas will be redirecting the Unionline URL to the updated Enerline address for a limited time. To ensure a seamless transition, we encourage you to change the link to on all your bookmarks and connections before the end of July 2021.

If you have any questions, please feel free to contact the Enbridge Gas Enerline Support team or your account manager.

Reminder: 2017/2018 Demand Side Management Deferral and Variance Account Clearing Adjustment

On Jan. 28, 2021, Enbridge Gas received approval from the Ontario Energy Board (OEB) to dispose of its 2017 and 2018 Demand Side Management (DSM) deferral and variance account balances (EB-2020-0067), resulting in a delivery adjustment being applied to bills for all customers who received in-franchise contract rate delivery services in 2018. The DSM program is our energy conservation program that is available to customers.

Reminder: to minimize the impact on customers receiving a charge, these balances are being uniformly disposed of over a three-month period effective April 1, 2021. Customers will see three equal installments over their April to June bills (received from May to July).

Coming in July - our newly designed website

This July, we will reach a significant milestone on our journey as a single, amalgamated company. While we are sad to say goodbye to, we are excited to launch our new, combined and updated website— Information for all our residential, business, commercial/industrial and storage and transportation customers will be housed in easy to locate areas with enhanced search and intuitive navigation, so that you can find the information you need, all in one place.

After July 6, take a look at our new updated site. At that time, we encourage you to check and update any old bookmarks and to set some new favourites.
