Performance & Labour and Material Bonds in Ontario: A Simple Guide for Developers and Lenders

In Ontario construction projects—especially commercial, multifamily, and CMHC-financed developments—bonding is a key requirement for managing risk.

Two bonds appear most often:

• Performance Bonds

• Labour & Material Payment Bonds

Understanding how they work—and why lenders insist on them—can prevent costly delays and financing issues.

What Is a Construction Bond?

A construction bond is a surety bond, not insurance. It is a three-party agreement between:

• Principal – the contractor

• Obligee – the owner, lender, or municipality

• Surety – the bonding company

If the contractor fails to meet contractual obligations, the surety steps in to protect the obligee.

Performance Bond (Ontario)

A Performance Bond guarantees that the contractor will complete the project according to the contract—on scope, quality, and timing.

What It Protects Against

• Contractor default

• Insolvency or abandonment

• Failure to meet contractual standards

Who It Protects

• Owners and developers

• Construction lenders

• Municipalities

Typical Coverage

• 50%–100% of the construction contract value

• Commonly required for:

  • CMHC-insured multifamily projects

  • Municipal and public-sector work

  • Institutional construction loans

If a default occurs, the surety may fund completion, replace the contractor, or pay damages up to the bond amount.

Labour & Material Payment Bond (Ontario)

A Labour & Material Payment Bond ensures subcontractors, trades, and suppliers are paid—even if the general contractor fails to do so.

Why It Matters in Ontario

Under Ontario’s Construction Act, unpaid parties can register construction liens, which can:

• Freeze lender draws

• Delay refinancing or sale

• Create legal exposure

This bond significantly reduces lien risk and keeps projects bankable.

Typical Coverage

• 50%–100% of the contract value

• Often required alongside a Performance Bond

When Are These Bonds Required?

Bonding is commonly required when:

• Financing CMHC-insured multifamily projects

• Securing institutional construction loans

• Building municipal or public infrastructure

• Working with sophisticated equity partners

Many lenders will not advance construction funds without confirmed bonding.

Common Misconceptions

• Bonding is not insurance — it protects the owner and lender, not the contractor

• Only large contractors can be bonded — smaller contractors may qualify based on financial strength and experience

• Bonds don’t eliminate risk — they reduce it, but don’t replace proper underwriting

Why Bonding Matters for Financing

From a lender’s perspective, bonding:

• Lowers completion risk

• Reduces lien exposure

• Improves draw certainty

• Supports stronger loan terms

For developers, proper bonding can be the difference between smooth funding and costly delays.

Final Takeaway

Performance and Labour & Material Bonds are foundational tools in Ontario construction projects. They protect capital, reduce legal risk, and are often non-negotiable for lenders and CMHC-insured financing.

Bonding should be addressed early in the financing process, not after commitments are signed.
