Understanding Surety Bonds: A Contractor's Guide
Surety bonds are not insurance for your business — they are a financial guarantee to the project owner. Here is what every Canadian contractor needs to know.
What is a Surety Bond? The Tripartite Agreement Explained
[PLACEHOLDER] A surety bond is a three-party agreement — called a Tripartite Agreement — between the Contractor (Principal), the Project Owner (Obligee), and the Surety (Guarantor). The Surety guarantees to the Obligee that the Principal will fulfil their contractual obligations. If the Principal defaults, the Surety steps in to remedy the situation.
Principal
The Contractor
[PLACEHOLDER] The contractor or company who purchases the bond and is obligated to perform the contracted work.
Obligee
The Project Owner
[PLACEHOLDER] The government body or private owner requiring the bond as protection against contractor default.
Surety
The Guarantor
[PLACEHOLDER] The insurance company (underwriter) that issues the bond and guarantees the Principal's performance.
Bond Type Comparison
| Bond Type | Purpose | When Required | What It Covers |
|---|---|---|---|
| Bid Bond | Guarantees the contractor will honour their bid if awarded the contract | At tender submission — before contract award | The difference between winning bid and next-lowest bid if contractor declines |
| Performance Bond | Guarantees the contractor will complete the project according to the contract terms | Upon contract award — before work begins | Cost to complete the project if contractor defaults mid-project |
| Labour & Material Bond | Guarantees subcontractors and material suppliers will be paid | Alongside the Performance Bond on public projects (required by law) | Unpaid claims from subs and suppliers, preventing liens on the property |
