Letter of Comment

This webpage provides a brief overview of what a letter of comment is and tips on how to prepare one.

What a letter of comment is

A letter of comment allows you to share your views and opinions on a project in writing. Your letter of comment will be part of the public record and be considered by the Commission of the CER when it makes its decision or recommendation.

Preparing a letter of comment

When writing your letter of comment, you should think about what you want the Commission to know, the facts and information that will support your view, and if the letter supports the point you want to make.

The letter of comment could highlight your views and concerns about the project, how it will affect you, and any information or expertise you have about the project. The letter can state your position on the decision or recommendation the Commission will make, as well as your thoughts about any conditions that should be applied if the project is approved.

Take time to organize your thoughts and consider the main messages you wish to communicate, ensuring that they relate to the list of issues the Commission is considering and the project’s scope. Try to be specific about how the project will impact you, and read over your letter to make sure it is clear and accurately conveys the points you wish to make.

Remember the Commission conducts its hearings in a respectful manner and we ask that you follow this same practice when writing your letter of comment. Also, be aware that form letters are not allowed and will be disregarded.

Formatting your letter

Make sure to include your name and contact information – such as address, phone number, and email address – and the name and file number of the hearing your letter relates to.

We recommend following the tips below as they will help the Commission and others as they read your letter.

  • Begin by describing your expertise, the relevant information you possess, how you are affected, and the topics on the list of issues that relate to your interest.
  • Separate each issue and point into separate paragraphs, and use headings.
  • Reference any supporting information you use.

Supporting information

Supporting information are the photographs, maps, and written information that support your position. Video or audio recordings are not accepted as supporting information.

When filing electronically, note that only PDF files under 10 MB can be uploaded. Make sure to include references to any documents that are not yet on the official hearing record, and when you refer to the application or the evidence of others, note the exhibit and PDF page numbers (e.g., Filing # C12337, Adobe page # X, paragraph # X).

Do not reference websites as their addresses and content may change over time. Include the information you want the Commission to see.
