The Association for public procurement professionals
The Ontario Public Buyers Association (OPBA) is a member-driven association representing, connecting, and advocating on behalf of public procurement professionals in Ontario and beyond. Our diverse membership welcomes procurement professionals from local, regional, and provincial governments, school boards, post-secondary institutions, public safety and transit agencies, and other public entities.
The OPBA provides relevant learning opportunities and access to a broad network to help build the knowledge and skills needed, whether you are starting your career, are a seasoned professional, or if procurement is only part of your multi-faceted role.
Our members, who are entrusted with the expenditure of billions of tax dollars on behalf of their agencies, are diligently focused on fairness, transparency, and accountability.
Elevate your value as a public procurement professional by joining OPBA today.
