Ice Facility Operator Certificate of Competency examination syllabus

Effective: June 2000

Application to undertake examination

A candidate must submit an application and the prescribed fee at least 30 days before the date of the examination. The examination consists of one paper, 3 ½ hour duration and 150 multiple-choice questions. Currently, the candidate is provided with the following items in the Examination room, but in the near future the candidate may be required to obtain their own items in the list:

  • Safety Standards Act and Power Engineers, Boiler, Pressure Vessel and Refrigeration Safety Regulation.
  • C.S.A. B-52.
  • A non-programmable calculator.

Note: If the items referenced above become the responsibility of the candidate, the candidate must show the items to the Examiner for approval. Mathematical Tables will be provided. No other reference material will be allowed. The candidate must show picture I.D. at the examination.
