What is the Fuels Certification Program?


The Ontario Ministry of Consumer and Business Services, through the Technical Standards and Safety Authority (TSSA), regulates the Gas Technician and Oil Burner Technician occupations. A certification structure for these occupations is in place, under the newly created Regulation and Technical Standards and Safety Act. Programs of study have been lengthened to accommodate knowledge and skills required to service today's more sophisticated gas and oil burning equipment.

All fuel certification programs and courses offered at Mohawk College are accredited by the TSSA. Mohawk's Stoney Creek Campus is an approved Certification Test Centre for all Fuel Certification examinations.
