How Windsor procurement works

The City of Windsor centralizes most buying through its Purchasing division which issues Invitations to Quote, Requests for Proposals and public tenders. Suppliers must follow the procedures published on the City purchasing and bid-opportunities pages and meet any insurance, bonding and registration requirements stated in each solicitation.[1] For legal authority and limits on municipal contracts see the Ontario Municipal Act and related provincial rules for municipal procurement.[3]
