Prequalification Letters
A prequalification letter is how an owner satisfies itself, before a tender ever goes out, that a contractor has a real relationship with a surety and has been underwritten. It is the lightest instrument in the surety toolkit and the one most often mistaken for something it is not.
What Is a Prequalification Letter?
The Surety Association of Canada puts it about as plainly as it can be put: a prequalification letter “is not a bond, nor is it a legal commitment. It is a letter from the surety to the owner that confirms the bondability of its contractor client.” By issuing one, the surety is acknowledging its relationship with the contractor and its level of confidence in them. It is expressly non-binding.
It is used at the Request for Qualification or Expression of Interest stage, before bidding opens. The owner gets comfort that the contractor is known to a surety and has been through underwriting. The contractor gets to clear a prequalification gate without asking its surety to commit to anything.
What a prequalification letter does not do:
- It does not guarantee that any bond will be issued on any project
- It does not bind the surety to the figures it states, which describe current appetite rather than a promise
- It does not substitute for a bid bond, an agreement to bond, or the final performance and payment bonds
- It does not survive a material change in the contractor’s finances or workload
Know the Difference
Four Instruments, Four Different Promises
Most of the trouble contractors have with a prequalification letter comes from submitting one where a different instrument was actually required. These four documents sit at four different stages and bind four different combinations of parties.
A prequalification letter is the right answer to exactly one of those four questions. Read the solicitation carefully. Sending the wrong one is a disqualification, not a request for clarification.
Prequalification Letter
Binds nobody. Signed by the surety, used at the Request for Qualification or Expression of Interest stage. It confirms the contractor is known to a surety and has been underwritten. It carries no obligation to issue any bond, and typically says so on its face.
Agreement to Bond
Binds the surety. Also called a consent of surety, an undertaking to bond, or a bid letter — in Canadian usage these are the same thing. It is a legal commitment that the surety will issue the final bonds if the contractor is awarded the work, but it is not itself a bond, and it is executed by the surety alone. See our agreement to bond page.
Bid Bond
Performance and Payment Bonds
Binds the contractor and the surety, post-award. The performance bond guarantees completion of the contract; the labour and material payment bond pays trades and suppliers who go unpaid. CCDC 221 and 222, both reissued in 2024.
One consequence is worth spelling out because it catches experienced people. A bid bond does not oblige the surety to issue the performance bond afterwards — the two are separate undertakings. That is precisely why owners ask for an agreement to bond alongside the bid bond, and why a prequalification letter, which commits to neither, cannot stand in for either.
Before You Call
What the Surety Will Ask For
A prequalification letter is the visible output of an underwriting file, not a document produced on request. Nothing is issued until that file exists, which is why a first-time request takes one to three weeks rather than an afternoon. Having these ready is the single biggest determinant of how fast it moves.
Year-End Financial Statements
Externally prepared statements for the most recent year end, and for every business under shared ownership rather than only the operating company. The level of assurance matters as much as the numbers — see the section below.
Interim Statements
A current balance sheet and profit and loss statement. These become important once you are more than about four months past year end, because by then the annual statements no longer describe the business the surety is being asked to support.
Work-in-Progress Schedule
Every job in hand with contract value, amount billed to date, costs incurred and cost to complete. This is the document that determines how much of your aggregate is already consumed, so its accuracy directly affects the number in the letter.
Aged Receivables and Payables
Listings rather than totals. Concentration in one customer, or a receivable that has been sitting past ninety days, tells an underwriter something the balance sheet alone does not.
Banking and Credit Facilities
Your operating line, its limit, current utilisation and any security granted. A committed facility with headroom supports capacity; a fully drawn line does the opposite.
Ownership and Indemnity
Corporate structure showing related entities, personal financial statements for the owners, and a general indemnity agreement. Surety is not insurance — anything the surety pays out it recovers from the principal, and the indemnity is how.
Apply four to six weeks before you need anything, not four days. Once a facility is established, tender-stage documents can usually be turned around within a day or two, but establishing the facility itself cannot be rushed and is the step contractors consistently underestimate.
For Contractors
What the Letter Actually Buys You
It Opens the Gate, Not the Door
A prequalification letter gets you through the qualification stage of a procurement of a procurement. It does not win you the work and it does not commit your surety, but without one you may not reach the stage where either becomes possible.
It Costs You Nothing Directly
Canadian brokers consistently report that prequalification letters are issued at no charge as part of an established surety facility. Premium attaches to the final performance and payment bonds, not to tender-stage documents.
It Is a Free Diagnostic
The number your surety puts in the letter is their honest read on your balance sheet, your backlog and your management. If it comes back lower than you expected, that is information worth having before you build a bid strategy around a figure you cannot support.
For Owners and General Contractors
What It Tells You About a Bidder
Third-Party Vetting You Did Not Pay For
A surety has examined the contractor’s finances, workload and track record before putting its name on anything. That is independent diligence on a bidder or a subtrade, done by a party with its own money at risk.
Reviewed at Least Annually
Sureties re-underwrite their accounts at least once a year, looking at backlog profitability, receivables and current results. A prequalification letter reflects a relationship under continuing review, not a one-time check.
Know What You Are Holding
Because a prequalification letter binds nobody, it belongs at the qualification stage and nowhere else. If you need certainty that bonds will be issued, ask for an agreement to bond at tender and the bonds themselves at award.
The Two Numbers
How Capacity Is Actually Set
A prequalification letter usually states two figures, and they mean different things. Neither is binding — they describe the surety’s appetite at the date of writing, not a promise.
Single Project Limit
- The largest individual bonded contract the surety will support at one time
- Driven by working capital, net worth and how the job compares with what you have already completed
- A common underwriting benchmark is that a project should not exceed roughly one and a half times your largest completed job
- It moves with experience as much as with capital — finishing bigger work is what raises it
Aggregate Limit
- The total bonded work you can carry at one time, measured on cost to complete rather than contract value
- Because it is measured that way, capacity replenishes as jobs are billed and closed out
- Unbonded work in progress counts toward it too, because it consumes the same people and cash
- A large pending award can consume your aggregate overnight, which is why the surety should hear about it early
On the numbers you will find quoted elsewhere. No Canadian industry body — not the Surety Association of Canada, not CCDC — publishes a working-capital multiple for bonding capacity. The benchmarks that circulate come from individual brokerages: working capital in the range of five to ten per cent of the total work programme, debt to equity above three to one attracting questions, and something in the order of a hundred and fifty thousand dollars of working capital or equity as a practical floor for a first facility. Treat those as indicative of how underwriters think rather than as a formula.
The one genuinely published Canadian multiple is not a surety’s at all. Ontario’s Ministry of Transportation rates contractors for its own prequalification at four times net current assets, excluding officer and director receivables, and caps a contractor with review-engagement statements well below what audited statements would allow. That is an owner’s rating system rather than a surety’s capacity calculation, and the two should not be confused — but it is documented evidence of how much the quality of your financial statements moves the number.
Diagnosis
Why the Number Came Back Lower Than You Expected
A prequalification letter is rarely refused outright. More often it comes back at a figure that will not support the work you were planning to chase. These are the usual reasons, and most of them are fixable.
Working Capital Is Thin
Current assets less current liabilities is the primary driver of capacity. A profitable contractor can still be capacity-constrained if the profits have been distributed rather than retained, or if they are tied up in receivables and equipment rather than liquid.
The Statements Do Not Carry Enough Assurance
Notice-to-reader statements provide no assurance and cap what a surety will support. A review engagement is generally the practical threshold for a facility of any size, and audited statements are what unlock the larger numbers.
The Aggregate Is Already Consumed
Remember that unbonded work counts. A contractor who feels they have room because only two of six jobs are bonded may find the surety sees a work programme fully committed across all six.
The Job Is Too Big a Step Up
Sureties look hard at a project that is a multiple of anything you have completed. Growth is supported; a leap is not. Incremental increases in the twenty to fifty per cent range read very differently from doubling.
The Structure Is Unclear
Related entities, shareholder loans, intercompany balances and receivables from officers and directors all get scrutinised, and related-party balances are routinely discounted or excluded from the working capital calculation entirely.
The Surety Has Been Kept in the Dark
Late statements, no interim reporting, no warning of a large pending award, or a WIP schedule that does not reconcile. Underwriters price uncertainty conservatively, and poor reporting reads as uncertainty.
What Actually Works
How to Move the Number Up
The number in your prequalification letter is not a fixed property of your business. It responds to a handful of things you control, and the ones that move it most are usually the least glamorous.
None of this happens in a fortnight. If you know what you want to be bidding in eighteen months, the work starts now.
Upgrade the Statements
Moving from notice to reader to a review engagement, and from review to audit, is the most reliable single lever available. It costs money and it takes a year-end cycle, but it changes what a surety can support more than almost anything else you can do.
Retain Earnings
Every dollar distributed is a dollar that is not in working capital. Contractors who want to grow their bonded programme generally have to accept leaving profit in the company for a period, and the surety will see the difference immediately.
Tidy Up the Related Parties
Shareholder loans, intercompany receivables and balances owing from officers and directors are commonly discounted or removed from working capital. Formally subordinating shareholder debt can have it treated closer to equity. Talk to your accountant well before year end.
Report Properly
An accurate, current work-in-progress schedule with real cost-to-complete figures, reconciled to the general ledger, is worth more than it sounds. It removes uncertainty, and uncertainty is what gets priced conservatively.
Close Out Completed Jobs
Because the aggregate is measured on cost to complete, finishing and closing work frees capacity directly. Deficiency lists and unbilled holdback that drag on are quietly consuming room you may want for the next award.
Add Depth Below the Owner
Sureties look at what happens if the principal is unavailable. Experienced project managers, an estimator who is not the owner, and a plausible succession plan all make a business easier to support at a higher number.
A useful sequence: get the prequalification letter first, whatever number it comes back at, then work backwards from the figure you actually need. A surety that has already underwritten you will tell you which constraint is binding, and that conversation is considerably more productive than guessing. If you are also arranging bid bonds, performance bonds or an agreement to bond, they all draw on the same facility and the same file.
Prequalification Letter FAQs
What is a prequalification letter?
A prequalification letter is a letter from a surety confirming that a contractor is known to it, has been underwritten, and is considered bondable. The Surety Association of Canada describes it as neither a bond nor a legal commitment, and states plainly that it is not binding. It is used at the Request for Qualification or Expression of Interest stage.
Is a prequalification letter the same as an agreement to bond?
No, and the difference is the whole point of the prequalification letter. An agreement to bond — also called a consent of surety — is a legal commitment that the surety will issue the final bonds if the contract is awarded. A prequalification letter commits to nothing. One is submitted at tender; the other is submitted at prequalification.
Can I submit a prequalification letter instead of a bid bond?
A prequalification letter is not a substitute, unless the solicitation expressly says so, and it almost never will. A bid bond is a three-party instrument executed by both the contractor and the surety, and it secures the bid itself. A prequalification letter binds nobody. Submitting the wrong document is a common cause of disqualification.
Does a bid bond mean I will get the performance bond?
No. The two are separate undertakings, and a surety issuing a bid bond has not thereby committed to issue the final bonds. That is exactly why owners request an agreement to bond alongside the bid bond, and why the distinction between all three instruments is worth understanding before you tender.
What does a prequalification letter cost?
Canadian brokers consistently report that a prequalification letter is issued at no charge as part of an established surety facility. Premium attaches to the performance and payment bonds issued after award, not to documents produced at the qualification or tender stage.
How long does it take to get one?
If you already hold a surety facility, a prequalification letter usually takes a day or two. If you do not, the letter cannot be issued until an underwriting file exists, and establishing that generally runs one to three weeks with complete information, longer if statements or a work-in-progress schedule are missing. Apply four to six weeks before you need anything.
How long is a prequalification letter valid?
There is no published Canadian standard for how long a prequalification letter stays current. In practice the letter is a snapshot tied to the financial statements it was written from, and sureties re-underwrite their accounts at least annually. Once you are more than about four months past your year end, expect the surety to want interim figures before refreshing it.
What is the difference between the single project limit and the aggregate limit?
The single project limit is the largest individual bonded contract the surety will support. The aggregate limit is the total bonded work you can carry at once, measured on cost to complete rather than contract value. Because of that measure, capacity replenishes as jobs are billed and closed, and unbonded work in progress counts toward it as well.
Are the figures in the letter binding on the surety?
No. The figures in a prequalification letter describe the surety’s appetite at the date of writing. Any actual bond depends on the specific contract terms, the bond forms required, and your work programme at the time. A material change in any of those can change the answer.
Why is my capacity lower than I expected?
Most often working capital, the level of assurance on your financial statements, or an aggregate already consumed by work in hand — including unbonded work. Jobs substantially larger than anything you have completed, unclear corporate structure and related-party balances, and thin reporting all pull the number down as well.
What is the fastest way to increase it?
There is no fast way, but the most reliable one is improving the quality of your financial statements, from notice to reader to review and from review to audit. After that: retain earnings rather than distributing them, subordinate or clear shareholder loans, keep an accurate work-in-progress schedule, close out finished jobs, and build management depth below the owner.
