Companies are required to notify the CER and the Transportation Safety Board of events.
- unauthorized activities
- operation and maintenance activities
Companies are to report these events and others through the online event reporting system, or OERS. A full list of events that are reportable using the online system are in the CER Event Reporting Guidelines. Activities the CER needs to be notified of are defined in regulations. Companies are expected to know their responsibilities and what is required of them.
If you are a member of the public and want to report an event, contact the CER at 403-807-9473.
