City of Oshawa Bid Opportunities Website

***The City of Oshawa is working on a website re-design that includes a new Bidding Opportunities web section. If you had previously registered an account on the City’s ‘Bidding Opportunities’ page, the account will need to be registered again. We apologize for the inconvenience, and we look forward to working with you in the future.***

This site allows potential Bidders to create a free Bidding System Vendor account. Bidders select commodity code(s) for goods, services and construction and the Bidding System will notify the Vendor by email of Bid opportunities matching their commodity code selection.

Bidders are solely responsible for ensuring their Vendor account information is kept current.

Oshawa’s Bidding System Features:

  • Bidders can obtain Bid Documents on-line
  • Bidders who have registered for a Bid Opportunity will be notified by email of addendums.

The following is a list of our current online bid opportunities. Please refer to the Status column in the list to determine if the bid is open, closed or awarded.
