Supplier Preserves a Brampton Construction Lien Days Before Deadline

The situation

Bilal kept the books for a small transportation company by day and ran a modest building supply business with his wife Ayesha most evenings and weekends. Ayesha worked shifts as a transit operator, and her schedule was often what made it possible for one of them to be free during business hours to take supplier calls and arrange deliveries. Between them, the supply business was a side venture that had grown steadily over a few years, delivering lumber, drywall, and fasteners to small renovation contractors around Brampton and the surrounding area. It ran on trust as much as on invoices: most of their customers were repeat contractors who paid within thirty or sixty days, and Bilal had never needed to chase anyone through a lawyer before.

One of their regular customers was a general contractor named Elena, who ran renovation projects for homeowners doing additions and basement conversions. Over about four months, Bilal and Ayesha's business supplied materials for a home addition Elena was building, delivering in batches as the framing and drywall stages progressed. The invoices, totalling roughly $58,000, went unpaid one after another. Elena offered explanations each time — a client who was slow to release funds, a bank draft that had not cleared — and Bilal, who had worked with her before without issue, kept extending credit, reasoning that a contractor he had supplied for three years without a single missed payment deserved the benefit of the doubt on this one project.

By the time the final delivery went out, Elena had stopped returning calls altogether. Bilal and Ayesha realized they were not dealing with a slow payer. They were dealing with a contractor who might not pay at all, and the $58,000 figure was large enough, against a side business that ran on modest margins, that it threatened the supply relationships they depended on to keep their own accounts stocked.

The problem: a deadline nobody had flagged

Unpaid suppliers and subcontractors on a construction project in Ontario have a tool that unpaid vendors in most other industries do not: a construction lien. Under the Construction Act, a person who supplies materials or services to an improvement to land can register a claim for lien against the property itself, giving them a security interest that can force payment or a sale of the property to satisfy the debt. It is one of the few remedies available to a small supplier that can outweigh the leverage of a much larger contractor or a homeowner who simply stops answering the phone.

The power of a lien comes with a strict and unforgiving timeline. The clock runs from the earliest of the triggers that apply to a claimant's role on the project. For the contractor holding the head contract, that is publication of a certificate of substantial performance, or the date the contract is completed, abandoned or terminated — not the last day materials showed up on site. For a subcontractor, the subcontract's own completion or abandonment is added to that list. Only those supplying below that level, such as a materials supplier or a worker, measure the deadline from their own last supply. What is never the trigger, for anyone, is the date of the unpaid invoice or the date the supplier gave up on being paid voluntarily. For a supplier still actively delivering to an ongoing job, last supply is usually what ends up controlling, but that has to be confirmed rather than assumed, since a substantial performance certificate published earlier in the project can move the deadline forward without the supplier ever hearing about it. Missing the preservation deadline extinguishes the lien itself, and nothing revives it — the security against the property is lost for good, and no amount of documentation proving the debt is real will bring it back. The debt is not lost with it: the unpaid party can still sue on the contract, pursue a trust claim against funds that passed through the payment chain, and use the prompt payment and adjudication route, all of which stand entirely apart from the lien. A second, later deadline then requires the claim to be perfected by starting a court action and registering a certificate of action against the title, or the preserved lien expires too.

Bilal and Ayesha did not know any of this when they came to Treadstone. They came in asking for help collecting an unpaid invoice, the same way they might have asked for help with any other overdue account, expecting a demand letter and perhaps Small Claims Court. During the first call, our team asked the one question that changed the shape of the file: when was the last date materials were delivered to that specific project?

The answer put the deadline only days away. Because the supply relationship with Elena had continued across several projects and the invoices had blurred together, nobody on the client side had been tracking the clock on this particular job. Bilal had been keeping the books for their business the way he kept the books for his day job — carefully, but organized by customer rather than by project and construction deadline, which is the organizing principle that actually matters for lien purposes. Had the call come even a week later, the lien right on this project would have already lapsed, leaving Bilal and Ayesha to pursue the debt as an ordinary unsecured claim — a weaker position against a contractor who was already difficult to reach and who, for all they knew, might not have meaningful assets in her own name to collect against.

What we did

1. Confirmed the last supply date with documentation. The lien deadline runs from the date of last supply, so the first task was pinning that date down precisely using delivery records and signed receipts, not memory. This also meant identifying which invoices related to which project, since Bilal and Ayesha supplied Elena on more than one job at the same time.
2. Registered the claim for lien against title immediately. With the deadline confirmed, we prepared and registered the claim for lien on the property's title within days, preserving the roughly $58,000 claim before the window closed. This step also required identifying the correct legal description and ownership of the property, since a lien is registered against the land, not against the contractor personally.
3. Notified the property owner directly. A registered lien becomes visible to anyone checking title on the property, including the homeowner who hired Elena and any lender financing the project. We sent formal notice to the owner, which is often what moves a stalled payment dispute, since an unresolved lien can hold up the homeowner's own construction financing or eventual sale.
4. Opened negotiations before perfecting the lien. Perfecting a claim for lien means starting a court action and registering a certificate of action, a more expensive and adversarial step. Before that second deadline arrived, we opened direct negotiations with Elena and, once it became clear she was not the one holding the funds, with the homeowner's representative, using the registered lien as leverage.
5. Tracked the perfection deadline in parallel. Negotiation does not pause the lien clock, and a settlement that collapses at the last minute is no excuse for missing a second statutory deadline. We prepared the court documents needed to perfect the lien — the statement of claim and certificate of action — and kept them ready to file on short notice, so that a stalled negotiation would not cost Bilal and Ayesha their security by accident a second time.

The outcome

Once the lien was registered and the homeowner understood that an unresolved claim against the title could complicate their own mortgage draws and delay their final inspection, payment moved quickly. Within about six weeks of registration, the outstanding balance of roughly $58,000 was paid in full, and the claim for lien was discharged from title as part of the settlement, well before the perfection deadline would have forced a court action. Elena's role in the negotiation shrank once the homeowner realized the money owed to Bilal and Ayesha had never actually been passed along to them, and the homeowner chose to pay the supplier directly and settle accounts with the contractor separately.

For Bilal and Ayesha, the case closed a debt that had looked increasingly like a total loss just weeks earlier, and it changed how they run the supply side of the business going forward. They now track the last-supply date for every project separately in a simple spreadsheet, even when the same contractor is buying materials for several jobs at once, and they treat any invoice more than a few weeks overdue as a signal to check the calendar rather than simply extend more credit and hope the relationship sorts itself out. What had been an informal, trust-based way of running a growing side business became a slightly more disciplined one, without losing the flexibility that let them win repeat customers in the first place.

The case also underlined how narrow the margin for error can be on a lien. Nobody involved had acted carelessly — Bilal kept records, Ayesha followed up on overdue accounts, and both of them had a genuine, good-faith relationship with a contractor they had worked with before without trouble. The deadline still nearly slipped past them, simply because nobody had connected an ordinary bookkeeping habit to a legal cutoff that runs on calendar days rather than on invoice cycles. That gap between good business practice and lien-specific deadlines is common, and it is why a quick check with a lawyer as soon as a payment goes seriously overdue on a construction project can matter far more than it would on an ordinary account.
