Alberta Landowners Sue Energy Regulator Over Orphan Well Cleanup Costs

Alberta landowners are taking the provincial energy regulator to court over allegations of a failure to properly fund the cleanup of abandoned oil and gas sites.

The lawsuit was filed on September 8, 2026, with the court seeking a ruling that the Alberta Energy Regulator (AER) is responsible for covering the costs of cleaning up orphan wells.

Orphan wells are abandoned oil and gas sites that have no clear owner or operator to take responsibility for their maintenance and cleanup. Landowners claim that the AER has failed to properly fund the cleanup of these sites, leaving them with significant financial burdens.

The court case highlights concerns over the financial implications of orphan wells on landowners and the environment.
