Infrastructure Ontario (IO)

Infrastructure Ontario is the Ontario Crown agency that leads the procurement and delivery of the province's largest public infrastructure projects — hospitals, transit and justice facilities among them — and has brought roughly $44 billion in projects to market using public-private partnership (P3) delivery. If you are bidding on a major Ontario public build, IO's processes, not a municipality's or a ministry's, usually govern.

What it is

Per Infrastructure Ontario, the agency is a Crown agency that leads the procurement and delivery of complex infrastructure projects, using what it calls a made-in-Ontario approach to delivering large, complex public infrastructure through public-private partnerships. To date IO has delivered approximately $44.4 billion in infrastructure projects and brought 161 major P3 projects to market. Under the P3 model — in Ontario historically described as alternative financing and procurement (AFP) — a private consortium finances, builds and often maintains the facility over a long contract term, while the public sector retains ownership and responsibility for the service delivered inside the building.

How IO procurements run

Major IO projects move through a staged process: projects are identified and screened, then procured through competitive stages that narrow the field from an open request for qualifications to a shortlist of teams invited to submit detailed proposals. The consortia that bid are typically joint ventures of constructors, equity investors and facility operators, supported by architects, engineers and specialty consultants — which is where most suppliers actually touch an IO project: as a subtrade or professional services firm to one of the shortlisted teams, rather than as a bidder to IO itself. Contract terms are set out in project agreements that allocate design, construction and long-term maintenance risk to the private partner.

What it means for vendors

Direct IO contracts are rare outside advisory and transaction work, so the practical route to IO-delivered projects is getting onto shortlisted consortia's teams early — during the RFQ stage, not after. That means tracking IO's project pipeline on its website, building relationships with the recurring consortium members, and being ready to demonstrate relevant Ontario-scale experience. P3 contracts also carry long-tail obligations: maintenance and performance standards over multi-decade terms flow down through the supply chain, so pricing and warranty positions need to reflect commitments made years before your portion of work is even performed.

Common questions

Does Infrastructure Ontario post tenders on CanadaBuys?

No. IO is a provincial Crown agency, not a federal buyer. Its procurement notices, pipeline and process documents are published through Infrastructure Ontario's own channels, so monitoring CanadaBuys alone will miss Ontario P3 work.

What is the difference between IO and the Ontario ministry building the project?

The client ministry defines the service need and remains the public owner; IO runs the competitive procurement, negotiates the project agreement and oversees delivery. Vendors deal with IO through the procurement phase and with the consortium on the ground during construction and operations.
