Construction Trust Claims in Alberta: When Unpaid Subcontractors and Suppliers Outrank Other Creditors
When a general contractor fails, the fallout runs straight down the construction pyramid. Subcontractors and material suppliers who did their work and delivered their product suddenly find themselves lined up as unsecured creditors of an insolvent company, staring at a recovery of pennies on the dollar while the bank and the equipment lenders divide what remains.
Except construction is not like other industries. Alberta's construction legislation contains a trust mechanism that can lift certain funds out of a failed contractor's estate entirely and reserve them for the subcontractors and suppliers the money was always meant to reach. Where it applies, the trust does not just improve an unpaid supplier's position in the lineup. It takes the money out of the lineup altogether.
The catch is that the Alberta trust is narrow, technical, and widely misunderstood. Businesses that know how it works can protect real money in a contractor insolvency. Businesses that do not usually discover it only after the window has closed.
The statutory trust in plain terms
Alberta's Prompt Payment and Construction Lien Act creates the trust. The concept is simple: when a project owner pays the contractor after a certificate of substantial performance has been issued for the contract, the money the contractor receives is not the contractor's to spend freely. It is impressed with a trust in favour of the parties the payment was supposed to flow down to, the subcontractors and suppliers who have not yet been paid for that work.
In other words, the law treats those funds the way it treats money held for someone else. The contractor holds legal title, but the beneficial interest belongs to the unpaid parties beneath it in the chain. A contractor that takes an owner's post-certificate payment and uses it to pay the bank, cover payroll on a different project, or fund general operations is spending money the statute says belongs to others.
If that framework sounds familiar, it should. It is the same trust logic that applies to payroll source deductions and GST/HST: money collected by a business that was never really the business's own. And just as with those obligations, the trust character of the funds matters most at the exact moment the business fails.
The critical limit: no certificate, no trust
Here is where Alberta differs sharply from some other provinces, and where most misunderstandings live.
Alberta's construction trust arises only on payments made after a certificate of substantial performance has been issued. Courts have confirmed the plain meaning of the provision: where no certificate of substantial performance exists on the contract, no statutory trust exists over the payments, no matter how sympathetic the unpaid parties are or how clearly the money was meant to flow down to them.
This makes the certificate a genuine dividing line. Progress payments made through the life of a project, before any certificate is issued, are not trust funds under the Alberta statute. The same dollars, paid a week after a certificate issues, are.
Other provinces take a broader approach. Ontario, for example, imposes trust obligations across the payment chain throughout the project, so that funds received by each payer are held in trust for the parties below them without depending on a certificate. Businesses that work across provincial lines should not assume the generous version of the trust follows them into Alberta. Here, the certificate is the trigger, and its absence is fatal to the statutory claim.
The practical consequence for subcontractors and suppliers is blunt: the certificate of substantial performance is not just an administrative milestone. It is the event that converts future payments into protected funds. Knowing whether and when a certificate has been issued on a project you are supplying is part of protecting your receivable.
Why the trust matters most in an insolvency
A trust claim changes everything about where you stand when the contractor becomes insolvent, for one fundamental reason: property a bankrupt holds in trust for others does not form part of the bankrupt's estate. It is not divided among the creditors. It never belonged to the bankrupt in the first place.
This principle has been tested hard in Alberta. Trustees in bankruptcy have argued that the provincial construction trust is really just an attempt to reorder creditor priorities, something provincial law cannot do in the face of the federal bankruptcy regime. Alberta's highest court rejected that argument, holding that the statutory trust, where its conditions are met, satisfies the ordinary requirements of a true trust and keeps the funds outside the estate. The country's top court declined to disturb that result.
The effect is dramatic. Funds caught by the trust are not shared with the bank, the landlord, the equipment lessor, or the general unsecured pool. They go to the trust beneficiaries. In a contractor insolvency where everyone else is measuring recovery in cents, a valid trust claim can be worth one hundred cents on the dollar of the trust funds.
There is one honest caveat. Because the trust must function like a real trust, the money has to be identifiable. Trust funds that were received and immediately dissipated, spent, mingled beyond recognition, are harder to recover than funds still sitting in an account or still owing from the owner. Speed and tracing matter, which is one more reason these claims reward creditors who move early.
Trust and lien are different tools, and you may need both
Subcontractors and suppliers in Alberta tend to know about builders' liens. Fewer appreciate that the lien and the trust are separate remedies that protect against different failures.
A lien is a charge against the project land itself. It secures your claim against the property, pressures the owner, and traps holdback funds. But liens run on short, unforgiving clocks: registration deadlines measured in weeks from when you last supplied work or materials, with longer periods for certain kinds of work. Miss the deadline and the lien right is gone.
The trust follows the money rather than the land. It attaches to payments moving through the chain after substantial performance, and it can matter precisely where a lien cannot help. Some projects cannot be liened at all, federally regulated lands being the classic example, and Alberta courts have recognized that the trust provisions can still operate in those situations. A supplier on an unlienable project is not automatically unprotected; the trust may be the remedy that remains.
The disciplined approach for anyone supplying construction projects is to treat the two as a pair: preserve lien rights within the deadlines as a matter of routine, and understand the trust as the second layer that becomes decisive when the contractor, rather than the project, is the problem.
What subcontractors and suppliers should actually do
Turning the trust from an abstract right into recovered money is mostly a matter of information and speed:
Track certificates of substantial performance on your projects. Certificates are required to be posted or made available. Knowing the date one issues tells you which payments upstream are trust funds.
When a contractor starts to wobble, ask the questions early. What has the owner paid since the certificate? Where did it go? A contractor's vague answers about post-certificate funds are a warning sign in themselves.
Move quickly when insolvency hits. Identify the trust funds, in the contractor's accounts or still unpaid by the owner, before they are dissipated or swept. Notify the trustee or receiver of the trust claim immediately; a trustee who knows funds are claimed as trust property must deal with that claim rather than simply distributing them.
Document your position in the chain. The trust protects those the payment was destined for. Your subcontract, invoices, and proof of supply on that specific contract establish that you are a beneficiary.
Do not abandon the claim just because the money moved. Diverted trust funds can sometimes be traced, and diversions of trust money raise claims beyond the corporation itself in some circumstances. These are fact-heavy questions worth professional advice before they are written off.
For creditors on the other side of the table, businesses owed money by a construction company for non-project debts, the trust cuts the other way, and it is worth understanding for exactly that reason: a construction debtor's bank balance may be smaller than it looks, because some of what appears to be the company's cash may be trust money that belongs to its subcontractors.
Frequently asked questions
What is the construction trust in Alberta? When a project owner pays the contractor after a certificate of substantial performance has been issued, the funds the contractor receives are held in trust for the unpaid subcontractors and suppliers on that contract. The contractor cannot lawfully use that money for other purposes while those parties remain unpaid.
Does the trust apply to all payments on a construction project? No. Alberta's trust applies only to payments made after a certificate of substantial performance is issued. Payments made before any certificate exists are not statutory trust funds in Alberta, which is narrower than the approach in some other provinces such as Ontario.
What happens to trust funds if the contractor goes bankrupt? Funds validly impressed with the trust do not form part of the bankrupt contractor's estate. Alberta courts have upheld the trust in bankruptcy, meaning the funds go to the subcontractors and suppliers they were destined for rather than being divided among the general body of creditors.
Is a trust claim the same as a builders' lien? No. A lien is a charge against the project land and must be registered within short statutory deadlines. The trust follows the money paid down the chain after substantial performance. They are separate remedies, and prudent suppliers preserve both. The trust can also matter on projects that cannot be liened at all.
What should I do if I suspect trust funds were spent on something else? Act quickly and get advice. Trust funds can sometimes be traced even after they move, and the strength of a claim depends heavily on how fast the funds are identified and how well your position as a beneficiary is documented.
The bottom line
In most industries, an unsecured supplier of a failed customer is simply an unsecured creditor, and the arithmetic of insolvency does the rest. Construction is the exception. Alberta law carves certain payments out of a contractor's estate and reserves them for the parties down the chain, but only when the conditions are met, and only for those who assert the claim before the money disappears.
The certificate of substantial performance is the hinge. Suppliers and subcontractors who track it, watch the flow of post-certificate funds, and move immediately when a contractor fails are playing a different game than the rest of the creditor pool. In a contractor insolvency, that difference is frequently the whole recovery.
