Conditions of Service

Hydro Ottawa is committed to providing our customers with safe, reliable electricity service. Our Conditions of Service define how we work with our customers and others to meet this commitment.

Hydro Ottawa's Conditions of Service (in PDF) are detailed in one important reference document for the customers, contractors, developers, retailers, generators and their agents, consultants and suppliers that we do business with on a daily basis. This document includes information on account administration including rates and conditions, billing procedures, and payment plan options. It also references the regulations and codes, which govern the services Hydro Ottawa provides. These include safety and inspection requirements as well as roles and responsibilities.

Effective April 1, 2019, this revised Conditions of Service (in PDF) replaces any pre-existing Conditions of Service document.

Hydro Ottawa recently completed a review of its Conditions of Service. The revised document (Version 8, Proposed), along with a list of the proposed changes, is now available for review and comment until Friday, October 22, 2021.

The proposed timeline for implementation is December 2021.
