The OACETT (Ontario Association of Certified Engineering Technicians and Technologists) is a provincial association in Canada which does not directly belong to an American or International engineering society. Instead, it is affiliated with the national association known as Technology Professionals Canada,
Engineering trade organizations have been established since the nineteenth century, beginning with groups like the American Society of Civil Engineers. These entities have helped shape the standards and education for engineering professionals. These associations serve as guardians of professional qualifications and standards for engineers, ensuring that members have the proper credentials and education. However, national associations can have international impact through their influence on the profession globally.
