"Deliverable in Ontario" means the buyer named Ontario as a region where the work can be performed. That includes opportunities marked for delivery anywhere in Canada, which an Ontario business can bid on just as easily. It is not a filter on which department is buying, and it is not the same as the provincial procurement covered further down this page. For the full picture, read how to find government contracts across Canada, or the plain-English guide to selling to government.
Where Ontario tenders actually live
There is no single website that lists every Ontario government contract. Public buying in Ontario sits in three separate layers, and each one publishes somewhere different. Work out which layer your buyer is in, then go straight to its home.
Layer one, the province itself. Ontario ministries and provincial agencies post their open competitions on the Ontario Tenders Portal, run on the Jaggaer platform. The portal sits under Supply Ontario, the province's centralized supply-chain agency, but Supply Ontario is the policy and Vendor of Record layer, not the site you bid on. Do not confuse the Ontario Tenders Portal with the separate Ontario Vendor Portal, which is a back-office tool for invoicing once you already have a ministry relationship.
Layer two, the broader public sector. Hospitals, universities, colleges, school boards and other publicly funded bodies each choose their own electronic tendering system, as long as it is open and accessible to Canadian suppliers. In practice that scatters them across MERX, bids and tenders, and Biddingo rather than one provincial site. Because there are hundreds of these buyers, each running smaller competitions, the broader public sector is often the more realistic entry point for a small Ontario vendor.
Layer three, cities. Municipalities each run their own portal, and no two big cities picked the same vendor. See the city directory below.
Layer four, federal buyers based in Ontario. Ottawa and the National Capital Region hold a large share of federal headquarters, so an Ontario business, and especially an Eastern Ontario one, sits close to federal buyers too. Those opportunities are on CanadaBuys, and they are the ones surfaced in the live feed at the top of this page. For the full national portal map, see our directory of every Canadian tender portal.
| You want to sell to | Look here | What it costs to reach |
|---|---|---|
| Ontario ministries and provincial agencies | Ontario Tenders Portal (Jaggaer), governed by Supply Ontario | Free to register, view, download and bid |
| Hospitals, universities, colleges, school boards | Scattered across MERX, bids and tenders, and Biddingo, each buyer picks its own | Browsing is usually free, some aggregators charge for alerts or bidding |
| Ontario cities and municipalities | Each city runs its own portal (see the directory below) | Varies by city, browsing is generally free |
| Federal departments, work delivered in Ontario | CanadaBuys, or the live feed at the top of this page | Free to browse and bid |
Who buys, and how much
One useful way to plan is to look at which federal buyers award the most contracts for work delivered in Ontario. A shortlist of departments tends to account for most of the activity, which tells you where a small business gets the best return on the effort of registering and building relationships.
Top federal buyers for Ontario-delivered work
Ranked by number of contract awards on record. Award data is published unaudited and lags the calendar by months, so read it as a guide to who buys, not a live scoreboard.
Award data window: Feb 15, 1996 → Jul 18, 2026 · CanadaBuys award notices (published unaudited, lags months)
Concentration is the story here. When a handful of buyers account for the bulk of the awards, the practical move is to learn those buyers deeply, get on their bidders lists and standing arrangements, and mirror the language of their solicitations, rather than spreading yourself thin across every department at once. When you are ready to respond, our guide to writing a winning government bid walks through how evaluators actually score.
Buy Ontario, and how to get on a Vendor of Record list
Ontario's procurement rules changed dramatically and recently. The Buy Ontario Procurement Directive took effect on April 13, 2026 and folded the older Building Ontario Businesses Initiative and the Restrictive Procurement Policy into one framework. Any guide still quoting a standalone BOBIA threshold is describing a superseded rule.
The underlying Buy Ontario Act received royal assent on December 11, 2025, and a companion Municipal Buy Ontario Procurement Directive took effect the same day as the provincial one, with some municipal requirements phasing in through the spring. The core idea for a bidder is simple: the directive sets preference tiers by the value of the buy, favouring local suppliers on smaller contracts and widening the field as the value rises.
| Buyer type | Procurement value | Preference goes to |
|---|---|---|
| Government entities | Below $34,700 goods, below $139,000 services | Ontario businesses |
| Government entities | $34,700 to $368,000 goods, $139,000 to $368,000 services | Canadian businesses |
| Government entities | $368,000 and above | Trading-partner businesses, with weighted domestic criteria |
| Broader public sector | Below $139,000 | Ontario businesses |
| Broader public sector | $139,000 to $368,000 | Canadian businesses |
| Broader public sector | $368,000 and above | Trading-partner businesses, with weighted domestic criteria |
| Any covered entity | $50 million and above | Must include an Industrial, Regional and Technology Benefit requirement |
Separately, the Broader Public Sector Procurement Directive requires hospitals, colleges, school boards and other designated bodies to run an open, fair and transparent process, and to compete openly at or above $139,000 through an electronic tendering system that all Canadian suppliers can reach. That $139,000 line matches the current interprovincial trade-agreement threshold, which is why the same number keeps appearing.
Getting onto a Vendor of Record arrangement
A Vendor of Record, or VOR, is the province's main mechanism for repeat, simplified access. It is a master agreement that lets ministries, and often hospitals, municipalities and school boards, buy from a pre-qualified list without a fresh competition each time. You do not apply for one, you win it.
-
Watch the Three-Year Outlook
Supply Ontario publishes a Three-Year Outlook naming upcoming enterprise-wide, multi-ministry and ministry-specific VOR opportunities, with their category and expected posting date, so you can prepare in advance.
-
Register free and set alerts
Register on the Ontario Tenders Portal at no cost and turn on email alerts for the categories you serve, so you see the Request for Bids the day it posts.
-
Respond to the Request for Bids
VOR arrangements are established through Requests for Bids run as a transparent competitive process. Meet every stated requirement, because a VOR is competed, not granted.
-
Sign the master agreement
Bidders who meet all the requirements and sign the master agreement with the government become Vendors of Record, pre-qualified for streamlined future purchases.
-
File your monthly usage reports
Once listed, Vendors of Record log in to submit monthly usage reports through the designated government portal. It is an ongoing obligation, not a one-time step.
Most existing Vendor of Record arrangements are grandfathered under the new directive, though the new fleet-vehicle requirements apply even through existing arrangements.
Where the big Ontario cities post
Each large Ontario city picked its own procurement platform, so there is no single municipal feed to bookmark. Here is where the biggest ones post, confirmed against each city's own procurement page.
| City | Where tenders are posted | Go to |
|---|---|---|
| Toronto | TO Bids portal, with bidding run on SAP Business Network (Ariba) | toronto.ca |
| Ottawa | MERX, with lower-value and construction work sometimes elsewhere | ottawa.ca |
| Mississauga | bids and tenders | mississauga.bidsandtenders.ca |
| Hamilton | bids and tenders | hamilton.bidsandtenders.ca |
Most other mid-size and large Ontario cities, such as London and Kitchener, appear to run on the same bids and tenders platform, each on its own city subdomain, and Windsor is often listed on Biddingo, though we have not confirmed those three against the cities' own pages, so check the city's procurement page before you rely on it. Mississauga has been reported as moving to a new platform during 2026, another reason to confirm at the source. The pattern to take away is that a vendor targeting several Ontario municipalities needs a separate account on each platform. There is no unified Ontario municipal tenders portal.

Bidding takes capacity. Ontario grants can fund it.
Winning government work often means hiring, buying equipment, or building the systems a bigger contract demands. Ontario has grants for exactly that, and many stack. It is worth knowing which ones you qualify for before you scale up to chase tenders.
