Final answer:
The Health Professions Act is the legislation that required the College to establish a continuing competence program, which is different from the Occupational Health and Safety Act's focus on general workplace health and safety.
Step-by-step explanation:
The piece of legislation that required the College to establish a continuing competence program is the Health Professions Act. The Occupational Health and Safety Act (OHSA), although important for general workplace health and safety, does not specifically mandate the creation of a continuing competence program for the College. The OHSA's main purpose is to protect workers from health and safety hazards on the job, setting general regulations that workplaces must follow, and ensuring that workers have the right to be informed about job hazards. In contrast, the Health Professions Act more directly relates to requirements for health professionals, such as the establishment of competence programs.
