Large infrastructure projects in Canada cost a lot and are often complicated. Governments use public-private partnerships (P3s or PPPs) to share risks, attract private money, and finish projects faster. The Canada Infrastructure Bank (CIB) is a key federal agency that helps make these projects possible. Instead of grants, the CIB offers repayable investments to support major infrastructure work.
For private companies and public sponsors, knowing how PPP infrastructure funding works can mean the difference between a stalled idea and a financed project.
The Canada Infrastructure Bank is a federal Crown corporation. Its job is to bring private and institutional money into public infrastructure. The CIB does not give grants. It provides customized, repayable financing to encourage private investment.
CIB investments focus on five priority sectors:
Projects must have a public benefit and be able to make money. This can be through user fees, long-term government contracts, or other payments.
PPP projects funded by the CIB usually include:
Private companies almost always join with a public authority, not on their own.
The Canada Infrastructure Bank offers repayable investments such as:
There is no set minimum or maximum funding amount. Each project is reviewed on its own, but most investments are large—often hundreds of millions of dollars.

Not every project or team can get CIB funding. Before you begin, make sure your project meets these basic requirements:
Fits one of the five priority sectors
The CIB only funds projects in green infrastructure, clean power, public transit, trade and transportation, or broadband.
Has a public sponsor
You need a government or public agency partner. Private-only applications are not usually accepted.
Can generate revenue
Your project must have a way to make money—such as user fees or long-term contracts—to pay back the investment.
Delivers a public benefit
The project should help communities, support economic growth, or improve the environment.
Large scale
The CIB usually invests in big projects with major impact.
If you’re unsure if your project qualifies, tools like GrantHub’s eligibility matcher can help you quickly check programs by sector, province, and funding type.
Getting funding through a PPP has several steps:
Early engagement
Project sponsors contact the CIB to see if their project fits with CIB goals.
Project development and screening
The CIB checks if the project is possible, how risks are shared, and how it will make money.
Due diligence
The CIB reviews the project’s financial, technical, and legal details to make sure it can attract private capital.
Investment decision and closing
Financing terms are set, often with other private lenders and investors.
This process can take many months or longer, depending on how ready and complex your project is.
To improve your chances, you should:
Good planning and teamwork between public and private partners are important for success.
Treating CIB funding like a grant
CIB investments must be repaid. Projects without a clear revenue plan are unlikely to move forward.
Approaching the CIB without a public partner
Most PPP projects need a public sector sponsor. Private-only proposals rarely succeed.
Underestimating preparation time
You need clear financial plans, risk checks, and buying plans.
Applying outside priority sectors
Projects outside the CIB’s five sectors will not qualify, even if they are strong in other ways.

The Canada Infrastructure Bank provides repayable investments, like loans or equity. It does not give non-repayable grants.
Q: Can private companies apply directly to the Canada Infrastructure Bank?

Q: Do projects need to generate revenue to qualify?
Yes. Projects must show a way to make money, such as user fees or long-term payments, to support repayment.
Q: How long does the CIB approval process take?
The process has several stages and can take months or more, depending on the project’s size and readiness.
Q: Is there a funding cap for CIB investments?
No fixed cap is published. Each investment is reviewed based on project size and impact.

Public-private partnerships can get large-scale infrastructure funding in Canada if projects are planned the right way. Make sure your project has a public sponsor, a strong revenue plan, and fits one of the CIB’s five sectors before reaching out.
