Final answer:
The OIQ controls membership through a licensure system that includes payment of annual fees and professional competency requirements.
Step-by-step explanation:
The Ordre des ingenieurs du Quebec (OIQ) controls its membership primarily through a system of licensure which includes annual fees and requirements of professional competence. Those looking to join must have an accredited engineering degree, relevant work experience, and pass a professional examination. Once admitted, engineers must pay a fee each year to maintain their status as a member of the organization. The control of membership does not involve peer review, government appointment, or random selection in the general process.
