CER oversight of recent incidents

We work hard to prevent any incident from happening. Whether it’s through an inspection, education about safety culture, or a technical review of an application, our job is to check that companies have everything they need in place to keep everyone safe. If an incident still occurs, our priority is to ensure that a company’s response protects people and the environment. The CER investigates pipeline incidents to determine whether applicable legislation and regulatory requirements have been followed.

If needed, we may:

Understanding what happened

After an incident, we need to find out what caused it. We also need to understand and act upon what we find out. Our goal is to make sure that we avoid a repeat of any incident. So, this is an important step for us, and one that we take very seriously.

The Transportation Safety Board (TSB) may also choose to investigate the causes of an incident affecting infrastructure we regulate. In these circumstances, the TSB becomes the lead federal agency investigating the cause and contributing factors. Our inspectors and technical staff work closely with the TSB during their investigation. However, the analysis and regulatory oversight we do during a TSB investigation is our own and is focused on preventing the incident from happening again.
