Bid Bonds

A bid bond is the security you post with your tender guaranteeing that, if your bid is accepted, you will sign the contract and provide the bonds the owner has specified. It tells an owner your bid has been underwritten by a surety — and unlike a certified cheque, it does not tie up a dollar of your cash. Stanhope Simpson has been arranging bid bonds and bonding facilities for contractors across Atlantic Canada for over 70 years.

What Is a Bid Bond?

A bid bond is a form of bid security. It is a three-party guarantee rather than an insurance policy: you as the contractor are the principal, the project owner is the obligee, and a licensed surety company stands behind the promise. The surety guarantees that if your bid is accepted you will enter into the formal contract and provide whatever bonds the tender documents specify.

That distinction matters. An insurer expects to pay claims and prices for them. A surety expects not to pay — and if it does, you repay it under the indemnity agreement you signed. Which is why a surety underwrites your company before it will put its name on your bid.

Because a surety issuing a bid bond is effectively pre-committing to the performance bond that follows, the underwriting happens before you bid rather than after you win. Arrangements need to be in place well ahead of tender day.

The Mechanics

How a Bid Bond Actually Works

Most published explanations get one thing badly wrong: they describe a bid bond as a deposit you forfeit. It is not. Here is what actually happens.

Three parties, not two

You are the principal, the owner is the obligee, and the surety guarantees your promise. Only you and the surety make commitments — the owner simply holds the benefit. Surety companies must be licensed federally or provincially to issue bonds in Canada.

What the bond guarantees

Two things: that you will enter into the formal contract if your bid is accepted, and that you will provide the bonds specified in the owner’s bid documents. Deliver both and the obligation is discharged.

The bond amount

Ten percent of the bid is the Canadian convention, though the percentage comes from the owner’s tender documents rather than the bond form itself. Some owners specify more, and on very large projects a lower percentage is sometimes used.

What the surety actually pays

Not the whole bond amount. It pays the difference between your bid and the price the owner legally contracts for with someone else — and only where that price is higher. The bond amount is a ceiling on the payment, not the payment.

The validity period

On the current CCDC form it is the period stated in the bid documents, or sixty calendar days from closing if none is stated. It can be extended by up to a further sixty days without notice to the surety; anything beyond that needs the surety’s prior consent.

The indemnity

If the surety pays, you repay it. That is the fundamental difference from insurance, and the reason a surety examines your finances before it issues anything at all.

A worked example. You bid $2,000,000 with a 10% bid bond, so the bond amount is $200,000. If you refuse to sign and the owner contracts with the next acceptable bidder at $2,120,000, the surety pays the $120,000 shortfall — not the full $200,000. If the replacement contract comes in at $2,400,000, the surety pays $200,000, because the bond caps it. And if the next bid is at or below yours, the owner has no loss and the surety pays nothing. In every case you reimburse the surety. Compare that with a certified cheque, where the money is already in the owner’s hands and the whole amount is exposed.

Standard Forms

The Bond Forms You Will Be Asked For

Canadian construction bonding runs on a small set of standard forms. Using the wrong one — or an altered one — is a live compliance risk on bid day.

CCDC 220 — Bid Bond

The national standard, reissued in May 2024 for the first time since 2002. The update removed the old tender-date field and introduced a defined validity period. If a form in front of you refers to a “Tender Date” or a fixed ninety-day acceptance period, it is the superseded version.

CCDC 221 — Performance Bond

Issued at award, commonly at 50% of the contract price. It guarantees you will perform the contract, and it is what your surety was implicitly committing to when it issued the bid bond.

CCDC 222 — Labour & Material Payment Bond

Also commonly written at 50%, it gives your subtrades and suppliers a route to payment if you do not pay them. Usually specified alongside the performance bond.

Federal form PWGSC-TPSGC 504

Federal work uses its own bid bond: 10% of the total bid to a maximum of $2 million, conditioned on providing a performance bond and a labour and material payment bond each at 50% of the contract price.

The owner’s own form

Many owners mandate their own wording. Some are well drafted and some are not — a poorly drawn form can end up giving the owner less protection than the standard one. Send any non-standard form to your broker before bid day, because the surety decides whether it will execute it, not you.

Execution details that fail bids

The correct obligee name, proper seals and signing authority, the right version of the form, and in some jurisdictions even the paper size. Nova Scotia Public Works, for instance, publishes its own bond forms and requires legal-size paper. These are entirely avoidable disqualifications.

The current bond forms are published by the Canadian Construction Documents Committee, and the Surety Association of Canada publishes plain-language guidance for contractors and owners. If a tender hands you anything other than the standard forms, send it to us before bid day — we would rather read it than argue about it afterwards.

Your Options

Bid Security: Four Options Compared

Owners often accept more than one form of bid security. They are not equivalent, and the difference shows up in your cash position and your bank line.

Bid bond

No premium per bond once a facility exists, no impact on your operating line, and exposure limited to the owner’s proven shortfall up to the bond amount. It also carries prequalification value — the owner knows a surety has vetted you.

Certified cheque or bank draft

Simple and instantly acceptable, but the cash sits in the owner’s hands and the entire amount is exposed if you default. On a $2 million bid that is $200,000 of working capital doing nothing for the length of the tender period.

Irrevocable letter of credit

Fast and certain for the owner, and expensive for you. It reduces your operating line dollar for dollar, usually requires cash security or covenants with your bank, and is payable on demand — the bank pays when asked, regardless of whether you were actually in default.

Agreement to bond

A letter from the surety confirming it will issue the performance and payment bonds if you are awarded the work. It provides the owner no financial security at all — which is precisely why owners often require it in addition to a bid bond rather than instead of one.

Bid Bond Benefits

What a Bid Bond Does for Contractors

Access to the work

Most public construction, and a large share of institutional and lender-financed private work, requires bid security. Without a bonding facility those tenders are simply closed to you.

Your cash stays in the business

A bid bond puts nothing on deposit and consumes none of your bank line, so working capital stays available for payroll, materials and mobilisation.

Credibility you cannot buy

A surety only bonds a contractor it has underwritten. Posting a bid bond tells an owner your finances, experience and capacity have been reviewed by a third party with its own money at risk.

Exposure capped at the shortfall

If something goes wrong, the surety pays the owner’s actual loss up to the bond amount — not the whole sum, as would happen with a forfeited deposit.

A path to larger work

A bonding facility is how contractors step up. Each bonded job completed successfully builds the track record that supports the next, larger single-job limit.

One facility, unlimited bids

Once the facility is set up, bid bonds, agreements to bond, consents of surety and prequalification letters are issued as you need them under a single annual fee.

Bid Bond Benefits

What a Bid Bond Does for Project Owners

Financial protection

If the low bidder walks away, the surety covers the difference between that bid and what you actually have to pay someone else, up to the bond amount.

Prequalified bidders

A bid bond means a surety has already examined that contractor’s finances, experience and capacity. It filters your bid list before you open a single envelope.

Certainty the final bonds will be there

The surety issuing the bid bond is effectively committing to the performance and labour & material payment bonds that follow at award.

A wider, more competitive field

Requiring bonds rather than letters of credit keeps capable contractors in the running. Cash and credit-line security shuts out good firms that simply are not cash-rich.

A defined measure of recovery

The bond sets out how the owner’s loss is calculated, which makes recovery cleaner than arguing over whether a deposit should be forfeited.

Getting Set Up

How Contractors Qualify for Bonding

A surety is extending unsecured credit rather than selling a policy, so the review is closer to a bank’s than an insurer’s. Sureties commonly summarise what they are assessing as the three Cs.

Character

Your reputation and track record. References from owners, consultants, subtrades and suppliers, your history of paying people on time, and how you conduct business generally.

Capacity

Whether you can actually do the work — experience on comparable projects, your people, your equipment, and critically the work you already have on hand.

Capital

Financial strength. Working capital, equity, debt levels, profitability across several years, and the quality of your banking relationship.

The financial statements

Sureties want externally prepared statements, generally three to five fiscal year-ends plus current interim figures. A notice to reader is often workable for a first, small facility; once bond limits move past roughly $1 million, a review engagement becomes the expected minimum.

The supporting package

Work-in-progress and work-on-hand schedules, completed jobs with the profit earned on each, aged receivables and payables, bank line details, resumes for key people, a continuity plan, and statements for every entity under common ownership.

The indemnity agreement

Every facility is secured by a general indemnity agreement signed by the company and personally by the owners. It obliges you to reimburse the surety for any loss, and usually comes with subordination of shareholder loans and a general security agreement registered against company assets.

None of this happens in an afternoon. Underwriting a new facility takes weeks, so the time to start is well before the tender you actually want to chase — and a broker who knows how to present your financials to the right market makes a material difference to the limits you are offered.

Chasing work you are not set up to bond?

We will tell you plainly what a surety will make of your financials, what limits to expect, and what to fix first — before you spend estimating hours on a tender you cannot post security for.

Capacity

Bonding Capacity: What Sets Your Limits

A bonding facility carries two limits, and contractors routinely run into the second one without realising it exists.

Single job limit

The largest individual bonded project the surety will support. It is driven by your financial strength, your experience on comparable work, and the people you have available to run it.

Aggregate limit

A ceiling on your total work programme, measured by cost still to complete — and it counts your unbonded work too. This is where contractors get caught: you can sit comfortably inside your single job limit and still be declined because the backlog is full.

What drives the aggregate

For general contractors it tends to track working capital. For heavy civil contractors, with equipment-heavy balance sheets, it tends to track tangible net worth.

A working rule of thumb

Roughly one dollar of working capital supports about ten dollars of annual work programme. It varies by contractor type, but it is a useful sanity check before chasing a step change in volume.

How you step up

Sureties increase single job limits incrementally from your largest successfully completed contract — commonly by half again to double, sometimes more where the work sits squarely in your wheelhouse.

How you grow capacity faster

Retain earnings rather than distributing them, close your year-end promptly, keep work-in-progress reconciled to your income statement, collect receivables, and keep your surety informed before they have to ask.

Cost

What Does a Bid Bond Cost?

Bid bonds are not priced bond by bond. The cost sits in an annual facility fee, and the real premium arrives on the bonds you post at award.

The bid bond itself

No premium per tender. Once your facility is in place, bid bonds, agreements to bond, consents of surety and prequalification letters are issued on request.

The annual facility fee

A single yearly charge, commonly in the range of $1,500 to $3,000 depending on the account, covering unlimited bid-stage instruments however often you tender.

Where the premium actually falls

On the performance and labour & material payment bonds issued at award — typically at 50% of the contract price each.

How the premium is calculated

Contract price divided by a thousand, multiplied by your rate. The contract price used is inclusive of HST, which is worth remembering in Nova Scotia.

What it comes to

A conventional 50/50 package sits around one percent of contract value, commonly between 0.7% and 1.5%. Rates are quoted on a declining scale, so the rate per thousand falls as contract value rises, and stronger contractors are rated better.

What triggers more premium

Contract increases attract additional premium, and decreases can be refunded. On contracts running beyond a year, a renewal premium is payable at each anniversary based on the work still to complete.

The Rest of the Programme

The Bonds That Follow a Bid Bond

A bid bond is the first instrument in a sequence. Getting the facility right means the rest of the programme is already arranged when you win the job.

Performance Bonds

Guarantees you will complete the contract. Issued at award, commonly at 50% of the contract price — and the bond your surety was effectively committing to when it issued your bid bond.

Labour & Material Payment Bonds

Gives your subtrades and suppliers a route to payment if they are not paid. Usually issued alongside the performance bond, at the same percentage.

Agreement to Bond

The surety’s letter confirming the final bonds will be available if you are awarded the work. Frequently required in addition to a bid bond rather than instead of one.

Prequalification Letter

Confirms to an owner that you are an approved surety account, often before a tender is even issued. Useful where owners prequalify their bid list.

Maintenance Bonds

Covers defects in workmanship or materials during the warranty period after the work is complete. Increasingly specified on public contracts.

Bid Bonds for US Projects

Bidding into the United States works differently — different forms, a different statutory framework and different surety requirements. Worth sorting out before you tender, not after.

Frequently Asked Questions About Bid Bonds

Whenever the tender documents call for bid security. That is standard on public construction — federal, provincial and municipal — and common on institutional, lender-financed and larger private work. Requirements differ by owner and by province, and thresholds change, so the operative answer is always in the specific tender. If you are unsure, send us the bid documents and we will read them.

There is no premium for the bid bond itself once you have a bonding facility in place. What you pay is an annual facility fee — commonly in the range of $1,500 to $3,000 depending on the account — which covers bid bonds, agreements to bond, consents of surety and prequalification letters however often you tender. The real premium falls on the performance and labour & material payment bonds issued at award.

The bond amount, or penal sum, is set by the owner’s bid documents — ten percent of the bid is the Canadian convention. It is not a deposit you forfeit. If you refuse to enter the contract, the surety pays the difference between your bid and what the owner legally contracts for with someone else, and only if that figure is higher. The bond amount is a ceiling on that payment, not the payment itself. A certified cheque works the opposite way: the whole amount is already in the owner’s hands.

Under the current CCDC bid bond, the validity period is whatever the bid documents prescribe, or sixty calendar days from bid closing if the documents say nothing. The principal and the owner can extend it by up to a further sixty days without notifying the surety; anything longer needs the surety’s prior consent. Note that the older 2002 form worked differently, using a fixed ninety-day period and a tender-date field. Route every extension request through your broker.

The owner re-tenders or contracts with the next acceptable bidder, and claims on the bond for the shortfall — capped at the bond amount, and subject to the owner taking reasonable steps to mitigate. The surety pays, and then recovers from the contractor under the indemnity agreement. The commercial consequence usually outlasts the financial one: withdrawing from a bonded bid affects your surety relationship and your capacity going forward.

Not by general law. It is a requirement of the owner’s procurement process. Some public procurement rules do make bid security mandatory above a stated contract value, and others leave it to the contracting authority — practice differs across the Atlantic provinces and changes over time. Read the tender, and where bid security is required check carefully whether the owner will accept a bond, a certified cheque, a letter of credit, or only one of them.

You do not apply bond by bond. You establish a bonding facility with a surety through a broker, and once that facility is in place bid bonds are issued on request — usually same or next day. Setting the facility up is the substantial piece: it is an underwriting review of your company, and it takes weeks rather than days. Start well before the tender you actually want to chase.

CCDC 220 is the national standard bid bond form, published by the Canadian Construction Documents Committee. It was reissued in May 2024 — the first update since 2002 — alongside CCDC 221 (performance) and CCDC 222 (labour and material payment). The 2024 bid bond removed the old tender-date field and introduced a defined validity period. The Surety Association of Canada has confirmed the risk profile of the forms did not change; they are clearer, not broader. If a form in front of you references a “Tender Date” or a fixed ninety-day acceptance period, you are looking at the superseded version.

A bid bond is financial security: it responds in money if you fail to enter the contract. An agreement to bond — sometimes called a consent of surety — is a letter confirming the surety will issue the performance and payment bonds if you are awarded the work. It provides the owner no financial security at all. The two are complements, not substitutes, which is why many tenders require both.

If the owner permits it, yes — but both are worse for you. A certified cheque ties up the full amount in cash and the whole sum is exposed if you default. An irrevocable letter of credit reduces your operating line dollar for dollar, usually requires cash security or bank covenants, and is payable on demand, meaning the bank pays when the owner asks regardless of whether you were actually in default. A bond costs you no cash, no credit line, and pays only a proven loss.

It is entirely at the owner’s discretion. Institutional owners, developers with construction financing and larger private owners commonly require bid security because their lenders expect it. Smaller private owners often do not. If you work mostly private and want to move into public tendering, getting a facility in place is the first step — not the tender itself.

If no contract is awarded, there is no failure to enter into a contract and nothing for the bond to respond to. The bid bond simply expires at the end of its validity period. Where an award is delayed rather than cancelled, watch the validity period and speak to your broker about an extension before it lapses.

No. A bid bond names one principal, one obligee and one specific bid. Each bidder needs its own bond from its own surety. Where contractors bid a project as a joint venture, the bond is issued in the name of the joint venture and the sureties of the participants underwrite it on that basis — which needs arranging in advance, not on bid day.

Increasingly, yes, but acceptance is owner by owner rather than universal. An e-bond is an encrypted, verifiable document carrying a digital signature and corporate seal, and it can be uploaded to tendering platforms or delivered as a secure file. Your broker needs an electronic power of attorney from the surety to issue one. Always confirm against the specific tender whether an electronic bond is accepted or an original is required.

Expect to provide externally prepared financial statements for the last three to five fiscal year-ends plus current interim figures, a work-in-progress and work-on-hand schedule, a list of completed jobs with the profit earned on each, aged receivables and payables, bank line details, resumes for key people, a continuity plan, and personal net worth statements for the owners. You will also sign a general indemnity agreement. Underwriting takes weeks, not days — so the answer to “how long” is: longer than the tender period you are currently looking at.
