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.

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.
