P3 — public-private partnership

In Canadian public procurement, a P3 (public-private partnership) is a long-term, performance-based approach to procuring public infrastructure in which the private sector assumes a major share of the responsibility — including financing and risk — for delivering and performing the asset, from design through to long-term maintenance. PPP Canada's working definition was narrower and operational: "typically, an eligible P3 or AFP will be a procurement where a private proponent designs, builds, finances and operates/maintains a given infrastructure asset."

What makes a P3 different from a normal tender

Under traditional procurement, payment and performance are largely decoupled: the government buys a design or a build and carries the operating risk itself. In a P3, a single private-sector team completes multiple project phases under one contract, risk transfers to the private partner, and payment is performance- or availability-based — the public partner specifies measurable outcome criteria rather than how to build. The federal characterization had four elements: provision of capital assets and associated services for a defined outcome; multiple phases delivered by one private partner; risk transfer to the private sector; and a performance-based payment mechanism.

Delivery models

Canadian P3s are labelled by which structural elements the private partner carries: DBF (design-build-finance), DBFM (adding maintain) and DBFOM (adding operate), among others. For the P3 Canada Fund, eligibility required meaningful private involvement in at least two of five elements: design, build, operate, maintain, finance. Ontario calls its program AFP — Alternative Financing and Procurement — administered by Infrastructure Ontario; other provinces run their own agencies and standardized document suites.

The federal program layer

PPP Canada, the federal Crown corporation created to expand P3 delivery, administered the P3 Canada Fund, a merit-based infrastructure program that co-funded qualifying P3 projects — the fund invested over $1.3 billion in 25 large or complex projects with combined capital costs above $6 billion, and its stated benchmark was value-for-money savings versus traditional procurement. Provincial programs mirror the structure: screening, business case, an RFX process with an RFQ stage qualifying a short list (commonly three teams) and an RFP stage selecting a preferred proponent.

What it means for vendors

P3s are team-of-teams procurements: constructors, operators, maintainers, financiers and advisors consort together years before a contract exists, and the competition is decided at the RFQ short-list stage. Subcontracting opportunities are real but flow through the short-listed proponents — track the project pipeline, not just the tender board.

Common questions

Is a P3 privatization?

No. The public partner retains ownership and accountability for the asset; the private partner delivers and performs under a contract with payments tied to availability and performance over decades. The Canadian Council for Public-Private Partnerships' broad definition — "a cooperative venture between the public and private sectors, built on the expertise of each partner" — stresses shared, allocated risk, not asset transfer.

How does a P3 compare to a construction contract?

A conventional public construction contract ends near substantial performance; a P3 bundles finance, maintenance and sometimes operations for 25–30+ years. The solicitation documents differ accordingly — see proposal vs. tender for the selection-mode shift.
