Executive Summary: Key Legal and Evidentiary Issues

• Lisa Thomson's claim of an oral contract with her father Al for reinstatement into the family business, A.R. Thomson Group (ARTG), was dismissed at trial and upheld on appeal.

• Essential terms including financing of Lisa's 15% partnership interest, her provision of services, and partner approval were found to be unresolved and uncertain.

• A significant "mismatch" existed between Lisa's available buyout funds (representing only 7.5%) and the claimed 15% interest, with no consensus on how the gap would be bridged.

• Post-conversation documents and correspondence, including Lisa's own affidavit and her lawyer's letters, never referenced a binding agreement, undermining her claim.

• The trial judge's adverse credibility findings against Lisa — citing a pattern of equivocation and inconsistency with documentary evidence — were unchallenged on appeal.

• No objective intention to create legal relations was established; the trial judge characterized the November 2009 conversation as a father's reassurance rather than a binding contract, and the Court of Appeal upheld that finding.

The Thomson family business and partnership structure

The A.R. Thomson Group ("ARTG") was a family partnership founded by Allan Roy Thomson ("Al") that operated in the distribution and manufacture of products for fluid containment and control, such as gaskets and valves. Al and his wife Patricia had five children — Jim, Debra, Gordon, Lisa, and Todd — each of whom held an indirect 15% interest in ARTG through corporate entities. Lisa's interest was held through 550934 B.C. Ltd. ("934"), which was jointly owned with her then-husband Gordon Taylor ("Taylor") through L.L.T. Holdings Inc. ("LLT"). ARTG functioned as a working partnership, meaning each partner's principal was expected to provide management services to the business, a principle embodied in the Partnership Agreement and considered fundamental to Al's vision for ARTG.

Lisa and Taylor's separation and the Default Notice

Lisa married Taylor in 1987 and separated from him in April 2005. Taylor had been a senior employee and eventually vice president of ARTG, attending partnership meetings and making decisions on behalf of 934 during the marriage. Following the separation, Taylor resigned from ARTG in August 2006 but maintained an indirect interest through 934 and LLT. In November 2007, Taylor acquired an interest in a competing business, placing him in apparent breach of the non-competition provision in the Partnership Agreement. On November 9, 2009, ART, as managing partner of ARTG, issued a Default Notice to 934, demanding the breach be cured within 60 days or 934 would be removed from ARTG.

The November 2009 conversation

On November 20, 2009, just days after the Default Notice was issued, Al and Lisa had a conversation — the "November 2009 Conversation" — that would become the crux of the entire litigation. Lisa maintained that during this conversation, Al orally agreed that she would be reinstated as a 15% partner in ARTG once matters with Taylor were resolved, and that she would use her share of the buyout funds to purchase the interest. ARTG denied that a contract had been formed. The trial judge ultimately found that the conversation amounted to reassurance by a concerned parent that his daughter would be taken care of, rather than the formation of a binding contract.

934's removal and the aftermath

Taylor did not cure the default, and on April 19, 2010, 934 was removed from ARTG by special resolution. The 15% partnership interest was valued at $1,781,214 under the Partnership Agreement's formula, with the expectation that Lisa and Taylor would each receive approximately half. Lisa cooperated with ARTG in defending the subsequent "Taylor Action" commenced by Taylor challenging the Default Notice. She also began part-time work at ARTG in late 2010, performing filing, event planning, and accounts payable functions for $20 per hour, but stopped in January 2012. She attended partnership meetings between 2010 and 2012 and prepared the minutes for those meetings.

Deterioration of family relations and conflicting correspondence

A series of events strained Lisa's relationship with her family. In July 2012, a fire in her apartment building led her to stay at the family's vacation property in Point Roberts, causing friction with her siblings. In August 2012, Lisa published the "99% Article," which portrayed her family negatively and drew disapproval from family members at a partnership meeting. In September 2012, both Lisa and her lawyer, Richard Attisha, wrote letters seeking a guarantee of reinstatement to ARTG — notably without referencing any pre-existing binding agreement from November 2009. Lisa's own September 2012 email to her brother Jim proposed "buying back in as a 15% owner" and acknowledged she would need an additional $750,000 beyond her share of the buyout funds, closing with a request for a written agreement. Jim's reply noted that terms and funding remained "to be determined." Between late 2012 and early 2015, communications about reinstatement continued, with Lisa at times vacillating on whether she even wanted to rejoin the partnership.

The Partnership Agreement's key provisions

Several clauses of the Partnership Agreement bore directly on the dispute. Article 7.2 required that the admission of a new partner and the terms of such admission be approved by special resolution (a 75% vote of the partners). Article 7.7 mandated that each partner provide management services to the partnership, reflecting the "working partners" principle. Articles 10.2, 10.4, and 10.5 addressed the termination of partnership interests and the valuation formula for terminated partners. These provisions were critical to the trial judge's analysis of what constituted essential terms of any reinstatement agreement.

The trial decision (2024 BCSC 2303)

Following a 23-day trial on liability in 2024, the trial judge dismissed both the Reinstatement Action and the Fraud Action. She found that Lisa's credibility had been "entirely undermined," citing a pattern of equivocation and inconsistency with documentary evidence. Particularly damaging was Lisa's February 2011 affidavit in spousal support proceedings, where she described needing to "seek approval" from ARTG to buy back in — a "striking contradiction to her testimony at trial." The judge concluded that no contract was formed during the November 2009 Conversation because the parties had not agreed on all essential terms — including the financing of the additional 7.5% interest, the services Lisa would provide, and how partner approval would be obtained — and because there was no objective intention to create legal relations.

The appeal (2026 BCCA 142)

Lisa and her corporate entities appealed to the British Columbia Court of Appeal, arguing that the trial judge erred in identifying the essential terms of the alleged contract and in concluding the parties lacked an intention to contract. On the first ground, the appellants contended that only parties, property, and price were essential, and that financing, services, and partner approval should not have been treated as essential terms. The Court of Appeal found no error of law, emphasizing that what constitutes an essential term is a fact-specific inquiry and that the trial judge properly engaged in that analysis. On the question of financing, the Court noted the fundamental "mismatch" between Lisa's available funds (representing 7.5%) and the claimed 15% interest. On services, the Court upheld the finding that the working-partner principle was fundamental to ARTG's operation. On partner approval, the Court observed that the Partnership Agreement expressly required a 75% vote for admission of a new partner, making this a logical essential term.

The ruling and outcome

On the second ground of appeal — intention to create legal relations — the Court of Appeal found no reviewable error, holding that the trial judge properly assessed all the circumstances, including the factual matrix, the conversation itself, and the parties' subsequent conduct. The Court concluded that the trial judge's characterization of the conversation as reassurance from a concerned father, rather than a binding contract, was supported by the evidence and owed deference. Ultimately, the British Columbia Court of Appeal unanimously dismissed the appeals, with Justice Warren writing the reasons and Justices Dickson and Horsman concurring. The respondents — James Thomson as Executor of the Estate of Allan Thomson and A.R. Thomson Group — were the successful parties. No specific monetary award was ordered on appeal, as the ruling simply affirmed the trial court's dismissal of both the Reinstatement Action and the Fraud Action; no exact amount was awarded or granted in the appellate proceedings.
