ERTH Power are the new owners of Westario Power. The Tillsonburg based utility with 25,000 electricity customers across southwestern Ontario conditionally purchased the Walkerton based Westario Power in December 2025. Ontario Energy Board approval was required to make the sale final. That happened on Oct. 15, 2026. ERTH Power says they plan to protect Westario jobs, and keep an office in Walkerton. Westario manages electricity distribution for 24,500 customers across midwestern Ontario.
