This decision is a useful reminder that a one-page handwritten-style share transfer document, drafted in the heat of a financing crisis, can absolutely bind your client years later, even where one signatory later insists he never meant to give up his shares.

In 9165-6462 Quebec Inc. v. DJB Mining Products & Services Ltd., 2026 ONSC 2375, Regional Senior Justice P.J. Boucher of the Ontario Superior Court of Justice granted specific performance of a brief, single-page Transfer Agreement under which a founder, Daniel Brunet, was to transfer 25% of his shares in two private corporations to a Quebec-incorporated investor in exchange for personal guarantees and the subordination of a shareholder loan. Six years after signing, Brunet refused to complete. The Court ordered the transfer and rectification of the corporate registers.

The One-Page Transfer

DJB Mining Products & Services Ltd. (DJB) was bleeding cash. A few months prior to the forbearance agreement, an accounting firm confirmed that DJB owed source deductions and HST in an amount close to $150,000, had outstanding accounts payable of $315,504 and had only $25,000 of credit remaining on its $425,000 line of credit. Its financial statements demonstrate that in 2019, DJB operated at a loss of $715,000. DJB was about to lose a long-running rent-to-own opportunity on the building it operated from. Government financing was conditional on closing by a specific date. Into that pressure cooker walked Madeleine Paquin, the applicant’s principal, with a one-page agreement she had prepared. Brunet refused to sign initially, asked for a right of first refusal at fair market value, and then signed. The agreement was barely longer than the signature block. It did not specify share certificate numbers, class, or a closing date. It did not name the bank to which the shareholder debt was being subordinated. DJB itself was not a party.

Why the Defences Failed

However, none of those gaps saved Brunet. Applying Capital Corp v. Creston Moly Corp. and Weyerhaeuser Company Limited v. Ontario (Attorney General), the Court read the document against the factual matrix and found its essential terms clear: half of Brunet’s holdings in each of two named corporations, in exchange for specified guarantees totalling $700,000 plus a $350,000 bank guarantee and the subordination of an identified $281,802 shareholder loan.

The use of the words convey and transfer, reinforced by Brunet’s own insistence on a right to repurchase the shares herein transferred, objectively defeated his later claim that he thought he was only pledging the shares as security.

Unconscionability failed because Madeleine in fact provided over $2 million of personal guarantees in the days after signing, satisfying the consideration.

Duress also failed because Brunet negotiated a term, had alternatives, met with corporate counsel within weeks, and then spent nearly four years ratifying the deal, including a 2022 text to his partner acknowledging the applicant’s ownership and asking to update the corporate records.

Estoppel by convention and a limitations defence likewise collapsed. The former because the parties’ conduct did not support the theory and the latter because discoverability was fixed in October 2023, when counsel for Brunet first refused to transfer, which was well within the limitation period.

Drafting and Advisory Takeaways

1. Sloppy share-transfer paper is still paper. If a client hands you a one-pager from a kitchen-table meeting and asks whether it is really binding, assume that it is. Missing share numbers, classes, closing mechanics or even the target corporation as a signatory will not defeat enforceability where the commercial purpose and consideration are objectively ascertainable.
2. When drafting on the other side, build out the mechanics anyway. A precisely papered transfer with closing deliverables, endorsement and book-entry steps, and a defined long-stop date avoids years of litigation.
3. Post-signing conduct ratifies contracts. Continued cooperation with financing, review of a draft shareholders agreement, and emails or texts acknowledging the new cap table will each be treated as confirmation. If your client believes a signed document is voidable for duress or unconscionability, they must act, repudiate in writing, and stop performing.
4. Where consideration is third-party credit support from the buyer’s principal, insist on a release-and-replacement covenant tied to closing. Brunet shows how long those exposures can persist when transfers do not actually complete.
5. On remedy, the Court reaffirmed that shares in privately held companies are typically unique enough to attract specific performance, with uniqueness assessed at the date of anticipatory breach. Damages-only carve-outs in private-company SPAs should be drafted with that doctrine in mind.

Takeaways for Transactional Counsel

For transactional counsel, Brunet is a cautionary tale about the half-papered deal and the client who signs first and rationalizes later. The lesson is not that informal agreements are bulletproof, but that Ontario courts will work hard, applying commercial common sense, to find a binding bargain where one objectively existed. Encourage clients to paper transactions properly the first time, to memorialize consideration as it is delivered, to insist on full closing of share transfers contemporaneously rather than relying on later goodwill, and to repudiate quickly and clearly if they genuinely believe they were coerced. Anything short of that risks a judgment, years later, vesting the shares in the counterparty.
