Become an intervenor
Intervenors are interested groups or individuals who participate actively in the proceeding either by submitting evidence, arguments or interrogatories (written questions) or by cross-examining a witness or witnesses at an oral hearing. Intervenors may include customers and other affected individuals, consumer and trade associations, environmental and regional interest groups, and other public interest groups.
To see the mandate and objectives of frequent intervenors in Board proceedings, as well as their membership and the constituency they represent, view the Annual Filings of Frequent Intervenors.
To request intervenor status, you must file a letter of intervention with the Board and send a copy to the applicant. Unless the notice states otherwise, the letter of intervention must be filed/sent no later than 10 days after the publication or service date of the notice of hearing for the application.
A letter of intervention must comply with Rule 22 of the Board’s Rules of Practice and Procedure, and include, among other things:
- the application file number;
- your contact information (name, address, telephone number, fax number, and email address);
- a description of how you are, or may be, affected by the outcome of this proceeding;
- the nature and scope of your intended participation;
- if you represent a group, include a description of the group and its membership; and
- whether you intend to seek an award of costs and the grounds for your eligibility.
If you are considering applying for cost award eligibility, please refer to the Board’s Practice Direction on Cost Awards. Your request should address the eligibility criteria in section 3 of the Practice Direction. The burden of establishing eligibility for a cost award is on the party applying for a cost award. A party found eligible for a cost award may not recover all the costs it claims. Consistency with the Board’s tariff, the conduct of the party during the proceeding, and the reasonableness of the final cost claim will be among the factors considered by the Board, as outlined in the Practice Direction.
Everything an intervenor files with the Board, including the intervenor's name and contact information, will be placed on the public record. This means all filings can be seen at our offices and will be placed on our website.
If you already have a user ID, please submit your intervention request through the Board’s e-Filing Service. Additionally, two paper copies must be submitted to the address set out below. If you do not have a user ID, you may complete a user ID/password request form (doc).
Parties must file their documents in searchable / unrestricted pdf format and use the document naming conventions and document submission standards outlined in the RESS Document Guidelines (pdf).
The Board also accepts interventions by email at the address below, and again, two additional paper copies are required.
Those who do not have internet access are required to submit their intervention request in PDF format on a CD, along with two paper copies.
All communications should be directed to the attention of the Board Secretary at the address below and, unless the notice states otherwise, be received no later than 4:45 p.m. on the required date.
