Procurement Activities The WSIB is committed to proactively addressing the challenge of rising costs and fiscal responsibility while maintaining the best possible care for injured workers. A part of that commitment is entering into strategic agreements for the products we purchase. When Procurement Activities are conducted by the WSIB -- such as issuing a Request for Proposal -- general information will be posted here with a link to the website(s) hosting the procurement activity. For purposes of tracking and accessibility, procurement activities are only available through established tendering websites. Each posting will remain on this page until one week after it closes. WSIB procurement activities are posted at these sites: MERX Biddingo There are no Requests for Proposals (RFPs) at this time.
