Halton Catholic Board Named Ontario's Most Energy-Efficient School Board for a Third Straight Year

Milton's Catholic schools are part of a board that is once again leading the province on energy efficiency. The Halton Catholic District School Board (HCDSB) has been ranked the most energy-efficient school board in Ontario for a third consecutive year.

What Happened

According to HCDSB, the board placed first in the 2026 Top Energy Performing School Boards Report: Sustainable Schools, which was released on June 4, 2026.

The report reviews publicly reported annual energy data from more than 4,800 schools and education facilities across 72 Ontario school boards. HCDSB placed third in the province in 2023, rose to first in 2024, and has held the top position since — a run the board says is unmatched by any other school board in Ontario.

Key Details

• The recognition is based on the 2026 Top Energy Performing School Boards Report: Sustainable Schools.

• The analysis covers more than 4,800 schools and facilities across 72 Ontario boards.

• HCDSB has now held first place for three consecutive years (2024, 2025 and 2026).

Community Impact

For Milton families with children in the Catholic system, the ranking points to lower operating costs and a smaller environmental footprint across local schools. HCDSB Chief Executive Officer and Chief Education Officer John Klein said the achievement "speaks to the collective efforts of our students, staff, school leaders" and the board's facilities team.

Background

The board has credited its facilities staff and ongoing energy-management work for the sustained results, which it says reflect efficiency improvements made across its school buildings over several years.
