Examination requirements for Compressor and Refrigeration Operator certificates changed January 1, 2016.

The essay format requirement for Compressor and Refrigeration Operator B has been eliminated, and Refrigeration Operator A exams no longer include a multiple-choice component. Please refer to the chart below for details.

Compressor Operator

    • 150 multiple-choice questions

    Refrigeration Operator B             

      • 150 multiple-choice questions

      Refrigeration Operator A

        • Essay-type, consisting of 5 questions

        The Operating Engineer Chief Officer’s decision to enact these changes reduces the burden on those entering the profession without compromising safety or efficacy of the process.

        These changes harmonizes Ontario requirements with all other Canadian jurisdictions (British Columbia, Manitoba, Nova Scotia, Prince Edward Island and Newfoundland and Labrador) who regulate the ‘Refrigeration B’ industry, and subscribe to the SOPEEC singular examination model.

        The remaining jurisdictions, with the exception of Quebec, which has adopted different standards, do not regulate the refrigeration industry.
