Distributor Bulletins
The Electrical Safety Authority releases Bulletins and Flash Notices periodically to quickly communicate new information to the Electrical Distribution Companies and other electrical distribution industry participants. Bulletins and Flash Notices address Regulatory requirements and other general industry issues.
We are currently in the process of updating the Distributor Bulletins and Flash Notices to be compliant with the Accessibility for Ontarians with Disabilities Act (AODA). We are also taking this opportunity to refresh the information to ensure references are up-to-date as well as updating the Bulletin and Flash Notice numbering system (addition of version identification).
- Bulletins and Flash Notices marked –v1 are considered AODA compliant and are not materially different then the documentation they’ve replace.
- Bulletins and Flash Notices marked –v2 are considered AODA compliant and will contain materially significant changes then the documentation they’ve replace.
- Until this process is complete some information may be missing from the website. If you are unable to find the information you are looking for, please contact Utility Regulations.
Reports
The Electrical Safety Authority produces reports and other documents related to Ontario Regulation 22/04 or other industry issues. These documents will report on ESA’s regulatory activity or provide additional information to the industry from a working group’s endeavours or other research activities.
