Reading an overbroad release narrowly to save a second, related claim

The situation

By the time Diego called us, one lawsuit had already been settled and closed, and it was making the second, still-open one worse. He owned a small rental building in Brampton, held personally rather than through his construction company, and two years earlier had hired a contractor named Hui to carry out a significant structural renovation to the building's lower floors. An engineer named Camila, a partner at a mid-sized engineering firm, had signed off on the structural plans and later certified the completed work.

Within a year, cracks appeared in load-bearing walls on the floor above the renovated area, and an independent inspection found the work did not match the certified plans in ways that compromised the structure. Repairs came to a substantial sum, tenants had to be relocated during the work, and Diego lost months of rental income across several units. Given his own background running a construction company, Diego felt confident enough to handle the dispute with Hui himself at first, and the two settled directly, with Hui's insurer paying an amount that covered only a portion of the repair costs.

Diego signed the release Hui's insurer's lawyer sent over without having a lawyer of his own review it. The release was broadly worded, releasing Hui and, as is common in these documents, anyone connected to the same claim from further liability related to the renovation. Diego did not think much of that language at the time. He still intended to pursue Camila's firm separately for its role in certifying defective work, and he assumed the two claims were unrelated enough that settling with one contractor would not affect the case against the engineer.

When Diego's claim against Camila's firm reached its early procedural stages, her firm's lawyers raised the release as a defence, arguing its broad language extinguished any claim connected to the same underlying damage, including the one against Camila, because the two alleged wrongs were part of the same chain of causation. Diego's own claim against Hui, filed and settled in one court location, and the ongoing claim against Camila, proceeding separately, now risked producing inconsistent results or, worse, no result at all if the release argument succeeded. Diego called us describing the situation as a matter that had somehow gotten worse after he thought he had already resolved part of it, and asked whether closing one file could really have poisoned another that had nothing to do with the amount he had already accepted from Hui.

The complication

The core problem was that Diego had two claims arising from one set of facts, being handled in two disconnected ways. The claim against Hui had already been resolved, badly, through a release that was broader than it needed to be. The claim against Camila's firm was still active, but it now had to be defended not just on its own merits, structural certification and whether Camila's sign-off met the standard expected of an engineer, but against an argument that it had already been extinguished by a settlement Diego had signed without appreciating what it gave away.

Ontario law generally allows parties to settle with one wrongdoer without automatically releasing others responsible for the same harm, but the outcome depends heavily on how the release is worded. A release that specifically and broadly extinguishes claims against anyone connected to the same loss, rather than being limited to the party actually signing it, can be read to sweep in others who were never part of the negotiation. Camila's firm was arguing exactly that reading, and the release Diego had signed gave them a genuine basis for the argument, not just a technical one.

Reopening a signed settlement is not something courts do lightly. A release is meant to bring finality, and courts are cautious about disturbing an agreement simply because one side later regrets its terms. What made this case different was that the release had not been the product of a real negotiation over its scope; it had been presented as standard paperwork, and Diego, despite his construction background, had no legal training in how release language operates or how far its wording could reach beyond the party who received the payment.

Compounding this, the two claims were also proceeding on different procedural tracks in different court locations, since the action against Hui had been filed and closed before Camila's firm was fully investigated, and the action against Camila had since been started separately. Even if the release issue could be resolved, having one judge hear evidence about the contractor's work without knowing anything about the engineer's role, and a different judge potentially hearing the reverse, created a real risk of two decisions that did not fit together, each based on only half the story.

There was also a cost dimension to the complication. Fighting the release argument as a standalone motion, disconnected from the merits of the claim against Camila, risked spending significant legal fees simply to get back to square one, with no guarantee the underlying claim against the engineer would then succeed on its own facts. Diego needed a strategy that resolved the release question and advanced the substantive claim together, rather than treating them as two separate fights fought one after the other.

What we did

1. Reviewed the release from the Hui settlement in detail to assess whether its broad language could genuinely be read to extinguish the claim against Camila's firm, or whether it was overreaching beyond what a court would actually enforce. This told us realistically how strong Camila's firm's defence was before deciding how hard to push back on it, rather than reacting to the argument on instinct alone.
2. Gathered the full record from the settlement negotiation, including the emails between Diego and Hui's insurer's lawyer, to show the release had been presented and signed without any discussion of its effect on other potential defendants. This mattered because a release negotiated in good faith about its scope is treated very differently from one signed without any real understanding of its reach or purpose.
3. Brought an application to address the release's scope directly, asking the court to interpret it as limited to Hui's own liability rather than as a blanket release of all connected claims, since the circumstances of how it was signed supported a narrower reading. This avoided having to unwind the settlement itself, which would have been a much harder ask with a lower chance of success.
4. Applied to transfer the claim against Camila's firm into the same court location where the original action against Hui had been filed, so both matters, even though one was closed, could be considered together by a single judge resolving the release dispute. Keeping them apart risked two judges forming different views of the same damage from two incomplete records. The court granted the transfer without a contested hearing, putting both matters on one timeline.
5. Sought consolidation of the procedural record so the judge hearing the release argument would have the full factual background, the contractor's work, the engineer's certification, and the resulting structural damage, in front of them at once, rather than reconstructing half the story from a settled file that was technically closed and thin on detail. This meant compiling the pleadings, correspondence and settlement documents from the closed Hui file alongside the live Camila materials into one brief, so nothing from the earlier action had to be summarized secondhand.
6. Retained an independent structural expert to assess whether the damage was attributable to the contractor's execution, the engineer's certification, or both, and to apportion responsibility between them where the evidence supported a split rather than an all-or-nothing finding. This gave the consolidated record an objective, technical basis for allocating responsibility rather than leaving the question to competing lawyers' characterizations of the same set of facts, which mattered once both defendants were being assessed together.
7. Negotiated with Camila's firm's insurer once the release argument was narrowed, using the consolidated record and the expert's findings to press the case on its actual merits, the adequacy of the structural certification, rather than let the dispute turn on a technical reading of paperwork from an unrelated negotiation. This shifted the conversation toward whether Camila's sign-off met the standard expected of a professional engineer. Anchoring the discussion to the expert's apportionment gave the insurer a concrete number to respond to instead of an open-ended dispute.
8. Reached a settlement with Camila's firm that reflected a fair share of responsibility for the certification failure, adjusted downward to account for the amount already recovered from Hui, since Diego was not entitled to recover the same loss twice from two different sources responsible for the same underlying damage. The adjustment was calculated openly against the expert's apportionment rather than negotiated blind, which shortened what could otherwise have been a lengthy argument over double recovery.

The outcome

The court granted the application to transfer and consolidate the two matters before it ruled on anything else, so the judge who ultimately interpreted the release also had the contractor's work, the engineer's certification, and the structural expert's findings in front of them as a single record, rather than deciding the release question in isolation from the facts it was supposed to resolve. On that combined record, the court accepted that the release from the Hui settlement was limited to Hui's own liability and did not extend to Camila's firm, clearing the path for the second claim to proceed on its merits rather than being dismissed on a technicality. That result depended heavily on being able to show the release had never been negotiated with Camila's firm in mind, a point that would have been much harder to establish without the original correspondence.

The claim against Camila's firm settled for an amount that, combined with what Diego had already recovered from Hui, covered a meaningful share of the total repair and lost rent costs, though still well short of the full loss once everything was accounted for. Diego's decision to settle with Hui early, without legal advice, had already given away negotiating leverage that could not fully be recovered later: the total repair and lost-rent bill came to just over $1.1 million once everything was tallied, and the combined settlements from both defendants recovered a little more than half of that figure, not the full amount.

Diego has since restructured how his construction company handles its own release language with subcontractors, adopting narrower, purpose-specific wording after seeing firsthand how broad language cost him leverage in his own case as a landlord. The building's structural repairs are complete, and the affected units have been re-let, but the file remains, for Diego, a lesson in how much a single signature on unreviewed paperwork can cost when more than one party shares responsibility for the same harm. He has also changed how he handles disputes involving his rental property specifically, treating it as a separate legal matter from his construction business even when the underlying issues, contractors and certifications, look similar on the surface. The units are re-let and the building is stable, but Diego describes the file as the most expensive lesson he has learned about the difference between resolving a dispute and simply closing it quickly.
