Surety bonds for contractors, explained

Published 9 October 2026 · Pantheon Strategic Ltd

Bid bonds, performance bonds, payment bonds and why bondability is a growth plan, explained from the Surety Association of Canada's own material.

Contractor meeting around a table

Sooner or later, a growing contractor in the Lower Mainland runs into a tender that says "bid bond required" or "50% performance bond and 50% labour and material payment bond". If you've never been bonded, it can feel like a locked door. It isn't. Surety bonds for contractors follow a clear logic, and understanding it is one of the most practical steps you can take toward bigger public and commercial work. This guide explains each bond, what it guarantees and how bonding fits into your growth plan, using the Surety Association of Canada's own explanations.

What a surety bond is (and isn't)

The Surety Association of Canada (SAC), the national association for the surety industry, explains that contract surety bonds are used primarily in construction and protect the owner (the obligee) from financial loss if the contractor (the principal) fails to fulfil the terms of the contract. The third party is the surety, the company that issues the bond.

A bond is not insurance for you, the contractor. If the surety pays out because you defaulted, it will look to you to repay it. SAC is explicit about bid bonds, for example: if a contractor doesn't enter into a contract after posting a bid bond, the resulting claim is something the contractor will be held responsible for reimbursing, corporately and usually personally.

SAC also notes that in Canada, surety bonds may only be issued by companies licensed to do so, federally or by a provincial insurance regulator.

The five surety products you'll see in tenders

SAC lists five commonly used contract surety products. The first three are used before or during tendering; the last two secure the contract itself.

ProductStageWhat SAC says it does
Pre-qualification letterRFQ / EOIA letter from the surety confirming the contractor's "bondability". Not a bond and not binding.
Consent of surety (agreement to bond)TenderA legal commitment that if you're awarded and sign the contract, the surety will provide the performance and/or payment bonds on the stated terms.
Bid bondTenderA three-party legal instrument assuring the owner the bidder is qualified and will follow through on its bid.
Performance bondContractGuarantees the contractor will perform the contract. Typically 50% of the contract amount, sometimes 100%.
Labour and material payment bondContractGuarantees the contractor will pay its direct trades and suppliers on the bonded project.

Surety bonds for contractors, one by one

Bid bonds: the entry ticket

SAC calls the bid bond the most commonly used risk management tool at the tender stage. The key point for your growth plan: SAC says that for a surety to provide a bid bond, the contractor must be pre-qualified and must meet the surety's criteria to be bondable for performance too. In other words, you can't get the bid bond without the surety already being comfortable bonding the whole job.

Performance bonds: a finished project, not cash

SAC explains that a performance bond gives the owner a completed project in line with the original contract even if the contractor defaults, and that the surety is never liable for more than the bond amount. It is also clear about what a performance bond isn't: not a source of quick cash, and not a tool for resolving ordinary disputes between owner and contractor. SAC encourages owners to call the surety early when performance problems appear, because the surety can sometimes help prevent a default.

Labour and material payment bonds: protecting your trades

SAC says a payment bond guarantees the bonded contractor will pay claimants with a direct contract to supply goods or services to the bonded job. Lower-tier subs and suppliers aren't protected under the standard form. Claims must be made within 120 days of the claimant's last day of work or supply on the project. SAC also notes that in most Canadian jurisdictions owners must hold back 10% from each draw as a reserve against liens. If you're a trade working under a bonded GC, those 120 days matter: track them.

How sureties decide whether to bond you

SAC's material makes clear that bonding is about prequalification: the surety has to be confident in the contractor before it issues anything, and a consent of surety is unlikely to be withdrawn unless significant new information emerges between bid and award. In practice, that means a surety will want to understand your business, your finances, your track record and the work you're taking on, usually through a surety broker. Exact underwriting requirements vary by surety, so ask your broker what they'll need.

Two practical takeaways:

Bonding as a growth strategy

Bonding capacity shapes which jobs you can chase. SAC lists project security for construction contracts as one of the most common uses of surety in the public sector, so a contractor without a surety relationship can find a lot of public work out of reach. Building bondability is therefore part of business development, not just paperwork. It's also why prequalification sits alongside bid strategy in how we work.
