Which organization registers certified gas and oil technicians in Ontario?

The Technical Standards and Safety Authority (TSSA) is the correct organization responsible for registering certified gas and oil technicians in Ontario. This organization oversees the safety standards for various technical sectors, including fuel safety for gas and oil. The TSSA ensures that technicians meet the necessary training and certification requirements, which helps maintain high safety standards within the industry. They also enforce compliance with regulations and provide oversight for the safe operation of gas and oil appliances and systems.

While the other organizations listed play important roles in different aspects of gas and oil industries or workplace safety, they do not specifically handle the registration of technicians. The Canadian Standards Association (CSA), for example, focuses on developing standards and certification for products, while the Canadian Gas Association primarily addresses advocacy and support for the natural gas industry. The Ontario Ministry of Labour deals with broader workplace safety issues and labor relations but is not directly involved in the certification process for gas and oil technicians.
