Executive Summary: Key Legal and Evidentiary Issues

• Plaintiffs sought damages for breach of contract arising from their 2015 purchase of DenKar Controls Inc., an HVAC business in North Bay, Ontario.
• At issue was whether the defendants failed to operate DenKar in the ordinary course of business — both before and after the share purchase agreement was reached — in breach of its representations, warranties, and covenants.
• Alleged breaches included slumping revenues, employee layoffs, solicitation of customers by a former employee, deteriorating business efforts and reputation, reduced insurance coverage, and reduced management salaries.
• Contractual clauses governing the absence of material changes, ongoing business conduct, insurance maintenance, and inventory formed the primary framework for the court's analysis.
• Even if a breach had been established, the court found the plaintiffs entirely responsible for their own damages due to their failure to exercise their contractual right to investigate DenKar's financial affairs before closing.
• Judgment was granted in favour of the defendants on their counterclaim for the balance owing on the promissory note.

Facts of the case

This case arose from the 2015 purchase of DenKar Controls Inc. ("DenKar"), a heating, ventilation, and air conditioning ("HVAC") business based in North Bay, Ontario. The plaintiffs — 1916458 Ontario Limited, Johnnie Miners, and Leanne Miners — purchased DenKar from the defendants, Denis Beaulieu and Karen Beaulieu, pursuant to a share purchase agreement ("SPA") dated November 28, 2014, and signed in December 2014. The deal closed on January 19, 2015, for a purchase price of $500,000. Denis Beaulieu, who was the driving force behind DenKar's success and the face of the business, passed away in 2017 at the age of 66; Karen Beaulieu participated in the litigation as his estate trustee.

DenKar operated across two revenue streams: HVAC services and building automation systems ("BAS"). It was the exclusive supplier of KMC HVAC controls in the region, giving it a captive service market for buildings using those controls. Between 1999 and 2009, revenues grew from approximately $185,000 to approximately $882,000. By 2013, revenues regularly fell in the $800,000 to $1,000,000 range. The Beaulieus had been planning to sell the business since 2009. Negotiations with the Miners began in May 2013 and continued for roughly one and a half years, with closing delayed primarily due to financing difficulties.

After taking over the business, the plaintiffs discovered emails, layoff records, and other documents that formed the basis of their claim. They alleged that DenKar's revenues had dropped substantially — from $719,126 for the fiscal year ending May 31, 2014, to an annualized equivalent of approximately $377,362 for the period ending January 19, 2015 — and that this decline was caused by the defendants' failure to operate the business in the ordinary course. The plaintiffs sought damages of $444,000, representing the difference between the $500,000 purchase price and the $56,000 valuation of DenKar's shares as of the closing date provided by their expert. In the alternative, they sought expectation damages of $86,000 per year for each of Johnnie and Leanne Miners for the years 2015 to 2018, during which neither was able to draw a salary. The defendants denied the claims and counterclaimed for the balance owing on the promissory note.

Key contractual terms at issue

The SPA contained several representations and warranties central to the dispute. Clause 4(1)(n), titled "Absence of Changes," provided that since May 31, 2014, to the best of the vendor's knowledge, there had not been any material change in the condition or operations of the company, other than changes in the ordinary and normal course of business and changes resulting from a general deterioration of markets in the industries in which DenKar was engaged. Clause 4(1)(w) required DenKar to maintain insurance coverage in amounts customarily carried by owners of comparable businesses, and that all such policies would remain in force until the closing date. Clause 4(1)(jj) warranted that inventories were in good and merchantable condition and carried on the books at the lower of cost and net realized value.

Clause 5(1)(a) obliged the company to conduct its business in the ordinary and normal course and required the vendors to use their best efforts to preserve the business and its customer relationships. Clause 5(2) granted the purchaser the right to access DenKar's books, records, and financial data between execution and closing to confirm the matters warranted. Clause 6(1) capped the vendor's indemnification obligation at an aggregate amount equal to the purchase price ($500,000), and clause 6(4) provided that the indemnification provisions constituted the sole remedy available to either party.

Court's reasoning and analysis

The court, per Justice M.G. Ellies, addressed each allegation of breach in turn and found none of them established on the evidence.

On slumping revenues, the court noted that DenKar's revenue history showed significant fluctuations throughout its existence — including drops of approximately 32 percent between 2012 and 2013, and 33 percent between 2007 and 2008 — and that a decline of approximately 48 percent, while significant, could not be said on a balance of probabilities to be outside the ordinary course of business. The court also found that the plaintiffs had themselves acknowledged the HVAC market was in a general slump, with Johnnie Miners writing in a June 2014 email that "the economy is affecting all sectors and a lot of companies have seen their earnings decline."

On Mr. Beaulieu's health, the court accepted Karen Beaulieu's evidence that Mr. Beaulieu's condition — myasthenia gravis, diagnosed in 2011 and controlled by medication — had no discernible impact on the operations of the business. The court noted that revenues grew steadily from 2009 to 2013 despite the illness, and that Mr. Miners himself noticed no deficits in Mr. Beaulieu's engagement during their meetings in May 2014.

On the layoffs, three employees — Peter McKenny, Grant Wilkie, and Darryl Stanley — were laid off on May 9, 2014. The court found that the SPA's representations and warranties applied only to the period after May 31, 2014, by which point two of the three employees had already been recalled. Stanley had independently found employment with a competitor, KRB Mechanical Ltd. The court further found that the plaintiffs were already aware that one HVAC employee was no longer with DenKar, and that the layoffs were in any case not proven to be caused by anything other than a deterioration of the HVAC market.

On allegations of deteriorating business efforts, the court found an extensive record of DenKar actively quoting and carrying out business after May 31, 2014, including numerous quotes submitted to school boards, government facilities, and commercial customers through to January 2015. Messages between Mr. and Mrs. Beaulieu suggesting the possible closure of the business were accepted as expressions of frustration caused by the prolonged and uncertain sale process, not evidence of any actual intention to shut down.

On insurance coverage, the court found that the reduction from $5M to $2M likely occurred in late 2014, after DenKar had already submitted relevant bids, and that there was no evidence the reduction caused DenKar to lose any particular job. Mr. Miners himself acknowledged during cross-examination that obtaining increased coverage when needed was not difficult after taking over the business.

On reduced management salaries — from $1,679 per week each to $500 per week each, reduced in or around September 2014 — the court found the plaintiffs had not established this was outside the ordinary course of business, noting that management wages had declined in prior years as well, and that the reduction was consistent with the general deterioration of the HVAC market.

On contributory fault, the court held that damages in contract cases can be apportioned based on fault, citing Arcamm Electrical Services Ltd. v. Avison Young Real Estate Management Services LP. The evidence showed that the plaintiffs had been repeatedly advised by their own accountant, Paul Innocente, against purchasing DenKar, and that Johnnie Miners himself acknowledged in writing that DenKar's revenue rebound was not guaranteed. The SPA gave the plaintiffs the right to access all of DenKar's books and financial data before closing. The court found that the plaintiffs could have discovered before closing everything they later relied upon, and that their failure to exercise that right — choosing instead to rely solely on the representations and warranties — made them entirely responsible for any loss they may have suffered.

Ruling and overall outcome

The court dismissed the plaintiffs' claim in its entirety, finding that the defendants did not breach the SPA. In the alternative, the court found that even if a breach had occurred, the plaintiffs were entirely responsible for their own damages by failing to avail themselves of their contractual right to investigate DenKar's affairs before closing. The defendants succeeded on their counterclaim: judgment was issued in their favour for the amount owing on the promissory note, calculated at $86,275.34 as of May 26, 2025, together with prejudgment and postjudgment interest at the rates prescribed under the Courts of Justice Act, R.S.O. 1990, c. C.43. The court also directed that the purchase price be adjusted to reflect its valuation of the inventory at $30,000, leaving the precise effect of that adjustment to be determined by the parties. Costs submissions were invited if the parties could not agree.
