When a Construction Bond Beats a Letter of Credit
You have an Ontario client with a project on the line. The owner or lender wants security. The bank is pushing a letter of credit. Your construction markets are talking about a construction bond. You are stuck in the middle, trying to protect your client’s cash and still keep the deal moving.
The trade-off is simple. A letter of credit ties up cash and bank credit. A construction bond uses surety capacity, so your client can keep working capital free for payroll, equipment, and materials. In many files, that difference decides whether they can take on another site or have to pass.
Right now, this trade-off matters more than it used to. Rates are higher. Carrying a big letter of credit limit hurts. Lenders are watching covenants closely. Owners are also fussier about wording, especially on Ontario projects that run over several years. Add a busy summer tender rush and you get pressure to accept whatever security option shows up first, even if it is not the best fit.
This piece is for Ontario retail brokers who know contract bonds, but feel less confident when someone says, “Can we swap this letter of credit for a bond?” You will see when that makes sense, when it does not, and what underwriters need from you before they say yes.
Where letters of credit still make sense
Letters of credit are not bad. There are files where they are still the cleaner answer.
Typical cases where a letter of credit fits well
- Small, short-term obligations where speed matters and the amount is modest
- Non-construction clients with no bond facility and no interest in financial disclosure
- Counterparties with strict policies that only reference letters of credit
Owners and lenders like letters of credit because
- They are simple to explain as a demand on a bank for cash up to a stated amount
- Bank paper is familiar to treasury, credit, and legal teams
- They see it as a pure financial instrument, with triggers they think they understand
What your client often misses are the hidden costs and side effects
- The letter of credit usually chews up operating line or term facility room
- Large limits can make covenant tests harder to meet, especially for seasonal contractors
- Annual renewals and re-papering bring the risk that the bank cuts back capacity at the worst time
For a quick, one-off obligation, a small letter of credit may be fine. For a long-term, construction-style risk, it might be the wrong tool.
How a construction bond can replace a letter of credit
A construction bond fits better when the underlying risk is about performance, timing, and quality, not pure financial exposure.
Good fits for a construction bond instead of a letter of credit include
- Performance or maintenance obligations on Ontario projects where your client is bondable
- Security for advance payments or holdback alternatives where the owner wants the work finished
- Long-term subdivision, site servicing, or warranty obligations that would tie up bank lines for years
A construction bond is a third-party promise from a licensed surety. The surety backs your client’s obligation to the owner, up to the bond amount. If there is a default under the contract, the surety can
- Step in and help complete the work
- Arrange another contractor
- Pay valid, supported claims, up to the penal sum
Sureties underwrite this as a mix of credit and performance risk. They are not lending cash like a bank. They are assessing whether your client can and will perform, then using their own balance sheet to back that.
Key advantages you can walk through with your client
- The bond facility usually sits outside their bank lines, so it does not crowd out borrowing capacity
- Over several years, the impact on cash and headroom is often better than a large letter of credit
- When there is a dispute, the surety investigates before paying, which helps avoid a sudden cash drain from an on-demand bank draw
Ontario contract examples where bonds work better
You will see good bond opportunities in many Ontario contracts once you start looking for them.
Typical examples
- Municipal or provincial work where owners accept performance, maintenance, or supply bonds as security
- Private commercial builds where lenders are open to bond forms from known sureties if the wording is clear
- Long-run service or maintenance jobs that used to rely on evergreen letters of credit
Types of construction bond that often replace letters of credit
- Performance bonds securing completion instead of a full-value development letter of credit
- Labour and material payment bonds that calm owner worries about subs and suppliers without locking up cash
- Subdivision and site-servicing bonds where municipal bylaws permit bonds instead of letters of credit
Timing matters too for Ontario brokers
- The summer tender rush is the moment to push back on automatic letter of credit demands and table bond wording early
- Winter is a good time to revisit existing contracts and talk about swapping security on renewal
- Every letter of credit renewal is a chance to ask, “Could this be a construction bond instead next term?”
What underwriters need before swapping LOC to bond
Surety underwriters can often support a switch from letter of credit to bond, but only when the file is clear.
You will move faster if you bring
- The contract or draft terms, so the obligation, duration, and remedies are spelled out
- Recent financial statements, work-in-progress reports, and a project list
- A summary of current letters of credit, with amounts, beneficiaries, and expiry dates, so a staged plan is possible
Expect your surety markets to ask
- Is this truly a construction or construction-style risk, or mainly a financial exposure like rent or margin calls
- How has the client performed on similar contracts in this trade
- How does the requested bond limit sit against net worth, working capital, and the current bonded program
Common misunderstandings to avoid
- Assuming any letter of credit can be swapped dollar for dollar without changing the triggers
- Telling clients a bond will always be cheaper than a bank solution
- Copying letter of credit on demand language into a bond form, which changes the risk for the surety and often kills the deal
Negotiating owners and lenders who say “LOC only”
You will still meet counterparties who say “We only take letters of credit.” That is often habit, not true policy.
First, get the actual security clause and ask what risk they are trying to protect
- Is it default, delay, poor quality, or simple non-payment
- How long do they expect to hold the security
- Do they already use bonds on other projects
Then you can offer
- Sample construction bond wordings that have worked on similar Ontario jobs
- A short comparison, focused on their concerns, of how a bond responds versus a letter of credit
Arguments that often land
- Contractors with surety support are screened for financial strength and capacity
- A construction bond is tied directly to the contract, so the response is aimed at fixing the actual problem
- Public and private owners across Canada already use bonds as a main form of security
Sometimes a bond will still be a non-starter, for example
- Foreign lenders with hard bank paper only rules
- High-volatility exposures like commodity margin calls
- Clients with weak financials where neither the bank nor a surety has much appetite
In those cases, it may come down to accepting a tighter letter of credit or scaling back the obligation.
Next steps to shift from LOC to construction bond
If you want to make this part of your regular process with Ontario construction accounts, a simple system helps.
On your next file
- List every existing and requested letter of credit
- Sort them into likely bondable performance, maintenance, subdivision, site servicing, and likely bank-only pure financial
- Pull the contracts and financials for the bondable list and bring them to a surety market that writes this class of bond in Ontario
When you sit with your client, focus on
- How much extra bank room they gain if even one large letter of credit is replaced
- The trade-off between more disclosure and indemnity versus better working capital
- Timing the change around renewals, refinancing, or new awards so they are not trying to shift security in the middle of a crisis
Over time, you can build a repeatable approach
- A one-page guide for producers that flags when a construction bond might beat a letter of credit
- A small library of acceptable bond wordings to send early in negotiations
- An annual review of key construction accounts before tender season, with a target list of letters of credit to replace over the next cycle
We work with Canadian insurance brokers every day on construction, commercial, and USA surety bonds, along with related commercial and construction insurance, and we see that this shift works best when it is planned, not rushed at the last minute.
