OneStop Outage – Maintenance Release

Currently, there are no planned Onestop outages. 

Annual Methane Emissions Reporting Moving to Petrinex

The AER is transitioning the reporting system for annual methane emissions from the OneStop platform to Petrinex. Updates will be provided as they become available.

What’s Changing?

  • Effective immediately, OneStop will no longer accept new annual methane emission reports.
  • Annual methane emission reports must be submitted through Petrinex once their reporting system becomes operational.
  • Annual methane emission reports submitted through OneStop after December 31, 2025, must be resubmitted via Petrinex.

What Remains the Same?
OneStop will remain available for amending past reports and submitting annual reports related to Directive 039 and Directive 084.

Water Licensing in OneStop

On June 2, 2025, the AER will begin to use OneStop to process applications for energy- and mineral-related water use licences (including temporary diversion licences) and water use submissions.

Associated acts, regulations, policies, and requirements for provincial water resources are not changing. Criteria for how water use licences are approved under the Water Act remain unchanged.    

Visit the “Water Licence Application Processing in OneStop” page to learn more about the systems change. 

Water Licensing Legacy Data Import

Please be advised that some existing (legacy) authorizations and submissions are still being added to OneStop, which may impact the creation of new submissions, renewals, and amendments.

As the AER continues to move data into OneStop, we will update the water licensing data migration list with the authorizations, submissions, and applications that are available in the system.

About OneStop

OneStop is the AER’s application review technology that processes energy- and resource-related applications in Alberta. 

When an operator submits an application into OneStop, the technology uses a complex set of rules to determine the necessary level of review. Lower risk applications (or components of an application) can be approved automatically through OneStop within minutes, as they’re considered routine with no impact on public safety or the environment. All other applications (or components of an application) are redirected to technical experts for additional review and assessment.
