SAC Headstart Subcontractor Performance Bond
A subcontractor performance bond is what stands behind a trade contractor’s obligation to finish its scope. The Headstart form is a variant built for one problem in particular: how long a general contractor waits for money and decisions after a subtrade walks off.
What Is the Headstart Subcontractor Performance Bond?
It is a subcontractor performance bond written to a different claims procedure. The Guarantee Company of North America created it in 2014, and ownership transferred to the Surety Association of Canada in April 2016 so that it could be issued industry-wide rather than by a single surety. It sits in SAC’s bond forms library with two companion documents, a notice of claim letter and a mitigation agreement.
Everything that distinguishes it happens after a default. The subcontractor performance bond does not change what is guaranteed — the subcontractor’s performance of its subcontract — and it does not change who the obligee is. It changes who gets to propose the solution and how fast the surety has to answer.
Two things it is not:
- It is not an automatic payout. There is no fixed percentage of the subcontract value released on notice, and no cheque that arrives simply because a default was declared
- It does not waive the surety’s investigation. The notice of claim letter expressly preserves the surety’s reasonable opportunity to investigate and reserves its rights and defences
- What it does give you is a defined route to restart the work in days rather than weeks, on a proposal you put forward yourself
- The bond amount remains the ceiling on the surety’s liability, as it does under any other subcontractor performance bond
The Mechanism
How a Headstart Claim Actually Works
The whole product is a claims procedure, so it is worth understanding the sequence before you specify the subcontractor performance bond form in a subcontract.
Where a conventional subcontractor performance bond leaves the general contractor waiting on the surety’s investigation and election, Headstart lets the general contractor put a plan on the table and get an answer to it inside a working week.
Step One: Declare the Default
The general contractor declares the subcontractor in default under the subcontract. This is the same trigger any performance bond requires, and it needs to be done properly — in writing, on the grounds the subcontract provides for.
Step Two: Take the Work in Hand
The distinctive requirement. The general contractor must also take the work out of the subcontractor’s hands. Doing both removes any argument about whether the surety’s obligation has been engaged, which is what makes the faster timetable possible.
Then You Choose the Route
Two options open up. The conventional one hands the problem to the surety, which investigates and elects how to respond. The Headstart Option is the alternative: the general contractor submits its own completion and mitigation proposal.
Three Business Days
Where the Headstart Option is taken, the surety has three business days to respond — approving the proposal or denying the claim. That deadline is the heart of the product, and it is the reason work can restart in days.
The Mitigation Agreement
An approved proposal is documented in a mitigation agreement between the general contractor and the surety. Shortfall payments are advanced under it as they are needed, rather than reimbursed long after the fact.
The Surety Still Investigates
Speed is not a waiver. The notice of claim letter preserves the surety’s reasonable opportunity to investigate and reserves its rights and defences. You are getting an accelerated route to restarting work, not an unconditional payment.
That last point is the one most worth carrying into a conversation with a subtrade or an underwriter. Headstart is not a demand instrument and it does not behave like one. Compare it with an on-demand bond, where the surety is barred from investigating at all — a genuinely different animal, and a much rarer one.
Which Trades
When to Bond a Subcontractor at All
Bonding every subtrade is neither normal nor sensible. A subcontractor performance bond costs money, consumes the subtrade’s own surety capacity, and prices smaller firms out of your tender list if applied indiscriminately. These are the situations where it usually earns its place.
A Large Share of the Contract
Where one trade carries a substantial percentage of the project value, its failure is no longer a scheduling problem — it is a solvency problem for the prime contract. Mechanical, electrical and structural packages are the usual candidates.
On the Critical Path
A trade whose delay stops everything behind it deserves security regardless of its dollar value. Curtain wall, elevators and specialised building systems frequently sit here.
Few Available Replacements
If the work is specialised enough that only two or three firms in the region can do it, replacing a defaulting subtrade takes months rather than weeks. That is precisely when a funded, fast route to a replacement is worth having.
Liquidated Damages Are in Play
Where your prime contract carries liquidated damages, a subtrade default converts directly into your exposure. Bonding the trades that can trigger that exposure is a straightforward transfer of risk.
An Unfamiliar Subcontractor
A firm you have not worked with, or one bidding well outside its usual size of project, is exactly what a surety’s prequalification is for. If a surety will not bond them, that is information worth having before award rather than after.
Signs of Financial Strain
Slow payment to their own suppliers, a large jump in workload, or a subtrade chasing a job that looks too big for them. A subcontractor performance bond does not fix any of that, but it puts a third party’s balance sheet behind the outcome.
Whichever trades you bond, the package normally mirrors the prime: a performance bond for completion and a labour and material payment bond so that the tiers below the subtrade get paid. Headstart is a variant of the first of those, not a replacement for the second.
For General Contractors
What the Headstart Form Changes for You
You Propose the Solution
Under a conventional subcontractor performance bond you wait for the surety to investigate and elect. Headstart lets you put your own completion and mitigation plan forward and get a decision on it within three business days.
Money Arrives as It Is Needed
Shortfall payments are advanced under the mitigation agreement rather than reimbursed after the work is done and the accounting is settled. On a trade that has stopped a critical path, that timing difference is the whole value.
Do the Two Steps Properly
The faster route depends on declaring the default and taking the work out of the subcontractor’s hands. Get either step wrong and you are back to arguing about whether the surety’s obligation was engaged at all — which is the delay you were trying to avoid.
For Subcontractors
What It Means If You Are Asked to Provide One
It Is Underwritten Like Any Bond
Your surety assesses the same things: working capital, the quality of your financial statements, your work on hand and your experience relative to the scope. Being asked for a Headstart form does not change the underwriting, only the claims wording.
It Consumes Your Capacity
A bonded subcontract counts against your single-job and aggregate limits in the same way a bonded prime contract does. If you are bonding several packages at once, that is a conversation to have with your surety before you tender, not after.
Being Bondable Is a Selling Point
General contractors bond the trades they are most exposed to. A subtrade that can produce a subcontractor performance bond on request is easier to award work to, and the prequalification behind it is third-party evidence that your finances and track record hold up.
Practical steps
Getting a Subcontractor Performance Bond Into Your Subcontracts
A subcontractor performance bond form only helps if it is called for early, sized sensibly and matched to the subcontract it secures. These are the points worth settling before a trade contractor mobilises, not after a problem appears on site.
Name the Form in the Tender
State in the subcontract tender package that the successful bidder must provide a subcontractor performance bond on the SAC Headstart form, and say who pays for it. Adding the requirement after award gives the trade a reason to reprice.
Size the Penal Sum Deliberately
Fifty per cent of the subcontract price is common practice, but a trade on the critical path, with long-lead material or few available replacements, is usually worth bonding at one hundred per cent. The exposure you are protecting is the cost to finish, not the value still unpaid.
Match the Bond to the Subcontract
The bond must name the correct legal entity, the correct subcontract and the correct price. Where change orders move the value materially, ask whether the penal sum should follow. A mismatch between the bonded subcontract and the one being performed is the most common reason a claim becomes difficult.
Check Who Is Behind the Bond
Confirm the surety is licensed to write surety business in the province and is a member of the Surety Association of Canada. Access to the Headstart form itself depends on the surety participating in the program.
Document From Day One
Schedule updates, deficiency lists, site instructions and written warnings are what support a default declaration later. A surety responding to a claim will ask for them, and the three-day clock in the Headstart process runs faster than a records search.
Give Notice the Way the Form Requires
Written notice of default to both the subcontractor and the surety, followed by genuinely taking the work out of the subcontractor’s hands, is what opens the process. Informal warnings and site conversations do not.
If you are unsure whether a particular trade warrants bonding, or whether the form on a subcontractor performance bond you have received is the one you asked for, send it to us before award. Reviewing a subcontractor performance bond takes minutes and is considerably cheaper than discovering a gap during a default.
Two different products
Subcontract Bonding Compared With Subcontractor Default Insurance
Subcontractor default insurance, usually shortened to SDI, is often presented as an alternative to bonding a trade contractor. The two products do not do the same job. A subcontractor performance bond is a three-party guarantee in which a surety stands behind the trade; SDI is a two-party insurance policy the general contractor buys to protect itself. The Surety Association of Canada set out the distinction in its position paper on subcontractor default insurance, and the practical differences below are the ones that matter when you are deciding how to protect a subcontract.
Subcontract Bonding
- Three parties: the subcontractor, the general contractor as obligee, and a licensed surety that guarantees performance of the subcontract.
- The surety underwrites the trade independently before issuing, so a second set of eyes reviews the subcontractor's finances, work in hand and management.
- Coverage is first dollar. There is no deductible and no co-payment, so the whole loss above the subcontract price sits with the surety up to the penal sum.
- A companion labour and material payment bond protects the subcontractor's own suppliers and lower-tier trades.
- The surety investigates and funds the resolution, and the subcontractor performance bond is a per-subcontract instrument that does not sit on the general contractor's balance sheet.
Subcontractor Default Insurance
- Two parties: the general contractor and its insurer. The subcontractor is the subject of the policy, not a party to it.
- The general contractor performs the prequalification itself and carries the consequences if that assessment proves wrong.
- Losses are shared. A first-dollar deductible and a co-payment above it mean a material portion of every default stays with the general contractor.
- There is no payment protection for the defaulting subcontractor's suppliers or lower-tier trades, which is why the Surety Association of Canada calls it misleading to promote SDI as a substitute for prime contractor bonding.
- Programs are usually enterprise-wide with substantial deductibles and annual premiums, which puts them out of reach for all but the largest general contractors.
Neither product is inherently better. SDI can suit a very large general contractor with a mature in-house prequalification department and the balance sheet to absorb deductibles across a portfolio. For most contractors in Atlantic Canada, a subcontractor performance bond delivers independent underwriting, first-dollar protection and payment security for the tiers below, and the Headstart form adds a faster route through the claim itself.
Headstart Subcontractor Performance Bond FAQs
It is a standard-form subcontractor performance bond published by the Surety Association of Canada. The form was developed by The Guarantee Company of North America in 2014 and ownership was transferred to the Association in April 2016, so it is now an industry form rather than a single insurer’s product. Like any subcontractor performance bond it guarantees that a trade contractor will perform its subcontract, and it names the general contractor as obligee.
The obligation is the same. What changes is the process after a default. Under the Headstart form the general contractor may put forward its own plan to complete or mitigate the subcontract work rather than waiting for the surety to select a resolution, and the surety commits to respond to that proposal within three business days. Shortfall costs are then advanced under a mitigation agreement as the work proceeds.
No. The form does not create a predetermined sum, a percentage of the subcontract price, or an automatic advance. Any figures you may see quoted in the range of half a per cent to one per cent are premium rates for subcontract bonding generally, not payouts. What the form provides is speed and a defined route through the claim, not a cheque of a fixed size.
Yes. The notice of claim preserves the surety’s reasonable opportunity to investigate the default, review the contract documents and verify the costs being claimed. The Headstart process runs alongside that investigation rather than replacing it, which is what distinguishes this subcontractor performance bond from an on-demand instrument where payment follows a compliant demand.
Two things, and both are required. The subcontractor must be declared in default in writing, with notice to the surety, and the work must genuinely be taken out of the subcontractor’s hands. A general contractor that continues to direct the trade on site, or that gives only informal warnings, has not met the condition that opens the process.
It is the document that governs how money moves once a Headstart route is agreed. Rather than settling a single lump sum at the end, the surety advances the shortfall between the remaining subcontract balance and the actual cost of completing the work, as those costs are incurred and supported. It keeps the completion funded while the final accounting is worked out.
Fifty per cent of the subcontract price is common, but the right answer depends on exposure rather than convention. A trade on the critical path, one with long-lead material, or one with few realistic replacements in the local market is often worth bonding at the full subcontract value, because what you are protecting is the cost to finish rather than the amount still unpaid.
Not by itself. A performance bond runs to the general contractor as obligee. Protection for the trade’s suppliers and lower-tier subcontractors comes from a companion labour and material payment bond, which is why the two are usually requested together on subcontracts of any size.
It is a different product, not an equivalent one. Subcontractor default insurance is a two-party policy the general contractor buys to protect itself, with a first-dollar deductible and a co-payment, and the general contractor performs the prequalification and manages the claim. It provides no payment protection to the defaulting trade’s suppliers, and the Surety Association of Canada has said it is misleading to promote it as a substitute for prime contractor bonding.
Yes. A subcontractor performance bond is underwritten in the same way as any other bond and draws on the same aggregate line, so it reduces what the trade can bond elsewhere while the work is in progress. That is a reason to bond selectively rather than universally, and a reason for trade contractors to keep their financial reporting current with their surety.
