Where are Ontario government and municipal tenders posted?

What is the Ontario Tenders Portal and who posts on it?

The Government of Ontario says vendors can find the government's open competitive procurements on Supply Ontario's Ontario Tenders Portal (OTP). The portal describes itself as the online bidding portal for procurement competitions within the government of Ontario and broader public sector (BPS) entities, and it is built on JAGGAER's eTendering platform.

Cost is not a barrier here. The portal says vendors can view and download opportunities without incurring a cost, and Supply Ontario says businesses can register for free and start submitting bids on open procurements. Registered vendors can bid online and receive alerts as new opportunities become available.

The portal is also where Supply Ontario sets up Vendor of Record (VOR) arrangements. Supply Ontario says VOR arrangements are established through requests for bids posted on the Ontario Tenders Portal, and enterprise-wide VORs give ministries access to contracted vendors for goods and services common to more than one ministry. If ministries buy what you sell through a VOR, the VOR competition is the one to watch.

Before bidding on larger provincial contracts, Supply Ontario requires a tax compliance verification number from the automated Tax Compliance Verification (TCV) program. Check Supply Ontario's vendor page for the current dollar value where this applies.

Where do municipalities, school boards, hospitals and universities post?

Ontario's Broader Public Sector Procurement Directive, effective April 13, 2026, applies to designated BPS organizations: hospitals, school boards, universities, colleges, children's aid societies and the purchasing corporations they control. It requires that calls for open competitive procurements be made through an electronic tendering system that is readily accessible by all vendors. It does not name a single system, so each organization picks its own.

Municipalities are not on that list of designated organizations, and they also choose their own platforms. A few examples from the buyers' own websites:

• City of Toronto: Notices of Intended Procurement are advertised through the Toronto Bids Portal (TO Bids), and selecting a posting takes you to the SAP Business Network to bid.
• City of Mississauga: you need an account with the City's eBidding system, which links to a bids&tenders site.
• City of Windsor: tenders and proposals are advertised on the City's Biddingo site.
• Toronto District School Board: its Bid Opportunities link goes to a bids&tenders site.
• University of Toronto: open competitive procurements are advertised on an electronic portal such as MERX.
• Niagara College: opportunities are posted on the Euna Procurement Portal, formerly Bonfire.

In my experience, this split is the main reason suppliers think the Ontario market is quieter than it is. They register on one portal, see a handful of relevant postings, and never realise the cities, boards and hospitals around them are posting somewhere else.

Where is federal government work in Ontario posted?

Federal government tenders are published separately, on CanadaBuys, when they are subject to one of Canada's trade agreements, and the Government of Canada's open data listing calls CanadaBuys the authoritative source for its tender notices.

CanadaBuys includes some opportunities from other levels of government. It says it will eventually become the single point of access for all tender opportunities across the Canadian public sector, and in the meantime it points businesses to other public sector tender sites, so it does not replace the provincial and municipal portals. You can subscribe to CanadaBuys alerts by email or through an RSS or ATOM reader.

How do I cover all Ontario public sector tenders?

1. Register on the Ontario Tenders Portal and set up alerts for the categories you sell in.
2. Set up CanadaBuys email or RSS alerts for federal work.
3. Write down the specific buyers you would actually work for: the cities, regions and counties in your service area, plus the school boards, hospitals, colleges and universities.
4. For each buyer, open the bid opportunities page on its own website and note which platform it uses.
5. Register on every platform those buyers use and set up category or keyword alerts on each one.
6. Check each buyer's own page on a regular schedule, because a posting that does not match your alert wording will not reach your inbox.
7. Download documents from the portal that posted the tender, and keep watching that posting for addenda until it closes.

Where do suppliers most often miss Ontario opportunities?

• Treating one portal as the whole market. The Ontario Tenders Portal covers the provincial government, but municipalities and many BPS organizations post elsewhere.
• Work below the open competition threshold. Under the BPS directive, open competition is required for goods and services of $139,000 or more. Below that, the directive recommends invitational competition with at least three suppliers invited, and that work goes to the suppliers the buyer chooses to invite.
• Invitation-only municipal work. The City of Mississauga, for example, says procurements below its posted thresholds are by invitation only.
• Vendor of Record arrangements. The directive's centralization appendix says hospitals, school boards, universities, colleges, children's aid societies and shared services organizations must use existing VOR arrangements whenever possible and appropriate, with compliance mandatory or voluntary depending on the funding ministry's authority. If you are not on the arrangement, that spending may never come to an open tender.
• Alerts that depend on exact wording. Keyword and category alerts miss tenders written in different terms, such as grounds maintenance instead of landscaping.
• Platform name changes. Niagara College now refers to the Euna Procurement Portal, formerly Bonfire. Bookmark each buyer's own bid page rather than relying on a platform name you remember.
