Certification: Operating Engineer

The Technical Standards and Safety Authority administers the certification and training of operating engineers.

The Technical Standards and Safety Authority (TSSA) oversees the certification and examination of operating engineers and operators to confirm their qualifications.

These activities ensure that all operating engineers and operators in Ontario have the skills and knowledge to safely manage, operate and maintain registered power plants.

There are eight different certification types within operating engineers. Each type has its own suggested study materials and certification requirements and has specific guidelines for candidates to follow in order to successfully apply for and obtain their required certification.

All require you to complete one or more examination(s) and submit an application form and fee.
