When it appears that a company has not followed AER requirements, the regulator takes steps to stop the noncompliant activity, restore the environment, and, if necessary, apply enforcement action against the responsible party. The AER completes investigations to determine all of the facts necessary to render an enforcement decision and works hard to ensure that this process is timely, fair, and transparent.

The information we can provide about an ongoing investigation is limited to protect the legal process and our ability to pursue all enforcement options

Investigations will be posted when the AER has a reasonable belief that an offence has occurred, a responsible party has been identified, and a notice of follow-up has been sent to that party.

A responsible party will not be liable if the investigation determines that they did everything they could have to follow the rules. Some investigations may be closed without issuing enforcement action if the AER determines that the responsible parties demonstrated due diligence by making a reasonable effort to follow all rules, regulations, and requirements or if the investigation is inconclusive (there was insufficient evidence).

The status will be listed as phase 1, 2, 3, or closed as the investigation progresses. Phase 1 is when AER staff collect information and conduct a site and incident assessment. Phase 2 involves the analysis of the materials collected. Phase 3 includes the final file review and enforcement response decision. The investigation tab will be updated on a monthly basis.

Archived investigation reports can be found on our website.
