The situation
Amina had built a group of physiotherapy clinics across the Niagara region over almost two decades, starting as a sole practitioner in St. Catharines and adding locations one at a time as the practice grew. Her sister Anne joined as a co-owner a few years in, taking on the administrative and clinical-staffing side of the business while Amina kept treating patients and overseeing clinical standards across every site. Their brother David held a smaller ownership stake; he was a software developer by trade, working full time for an unrelated employer, but the scheduling and patient-records system he had built for the clinics in his spare time had become one of the group's more valuable assets, licensed internally across every location and, by the time of the sale, running the day-to-day operations of the entire business.
By the time a national healthcare consolidator made an offer to buy the group outright, the three siblings owned a business worth enough that the sale price landed at roughly $38 million, reflecting the value of the clinic leases, the patient base, the staff, and the software David had written. The buyer's letter of intent set an ambitious closing date, tied to the start of its own fiscal quarter, and made clear the date was not very flexible — its financing and integration planning were built around it, and it wanted the acquired clinics folded into its reporting systems before that quarter began. Our firm was retained to run the legal side of the sale, including confirming what regulatory steps stood between signing and closing, and how much time each of those steps would realistically take.
The regulatory problem
Large business acquisitions in Canada can trigger a requirement, under the Competition Act, to notify the Competition Bureau before the deal closes. Whether notification is mandatory depends on two separate thresholds: one based on the value of the assets or revenues involved in the transaction, and another based on the combined size of the parties to the deal. Both have to be met for the notification requirement to apply, and both are set high — well above the value of most private business sales, including a clinic group the size of Amina, Anne and David's. Below either threshold, no filing is required at all, and the great majority of business sales in Canada never touch this process.
The buyer's own deal team had assumed the opposite. Because the buyer was a large national operator with revenues that cleared the party-size test many times over, its counsel had flagged the acquisition internally as one that would likely require a Competition Bureau filing, and had built weeks of buffer into its target closing date to absorb a waiting period it treated as unavoidable. Our review compared the actual transaction value and the target's revenues against the current size-of-transaction threshold, and the deal came in well under it. A large buyer does not by itself make a transaction notifiable — both tests have to be met, and this one never approached the dollar threshold that would have required a filing.
The risk was not that the deal would be blocked; nobody, including the buyer's own team, expected the Bureau to object even under its original assumption. The risk was that if nobody corrected the assumption, the buyer's deal team would keep the extra weeks built into the closing schedule for a filing and waiting period that did not need to exist, pushing the closing date later than the family had been told it would be.
There was also a quieter point worth making to the family directly, filing requirement or not: sharing competitively sensitive information with a buyer, or acting as though the two businesses were already combined before closing, can raise separate concerns under the Competition Act regardless of whether formal notification applies. Because Anne handled staffing and Amina handled clinical operations day to day, we walked both of them through what could and could not be coordinated with the buyer's team while the deal was still pending.
What we did
- Assessed notifiability early, before terms were finalized. Rather than waiting for the buyer's assumption to go unchallenged and harden into a scheduling fact everyone treated as settled, we ran the Competition Act threshold analysis ourselves once the buyer's financial information became available during early negotiations. Doing this before the letter of intent was signed let us shape the proposed closing date around the real regulatory picture, instead of trying to unwind weeks of buffer the buyer's team had already built in.
- Documented the threshold analysis in writing. We set out the transaction value, the target's revenues, and the current size-of-transaction threshold side by side in a short memo, showing plainly and with the underlying numbers why the deal fell short of the level that would trigger mandatory notification. Putting the comparison on paper, rather than asserting a conclusion verbally, gave the family something concrete to rely on and gave the buyer's own lawyers a starting point they could check rather than take on faith.
- Raised the analysis with the buyer's own competition counsel before its timeline was finalized. We sent the memo directly to the buyer's lawyers rather than waiting for them to ask, since the schedule that needed correcting was theirs, not ours. Once the buyer's lawyers reviewed the numbers independently, they agreed the transaction was not notifiable and confirmed in writing there was no basis for treating a waiting period as a closing condition, removing the one assumption standing between the family and the date they had been promised.
- Kept the family informed of what the assessment did and did not mean. Amina, Anne and David had understandably assumed a federal filing was simply part of any large sale, and worried that ruling it out might look like a corner being cut. We explained plainly that notification only applies once both the transaction-size and party-size thresholds are met, that neither applied here, and that this was a routine question every deal of this size has to check, not a sign of hidden risk in their own transaction.
- Coordinated with the buyer's counsel on a corrected timeline. With the assumed filing and waiting period removed from the schedule, we worked with the buyer's team to rebuild the closing timeline around the family's other genuine conditions — financing, landlord consents, and licence transfers — rather than around a regulatory step that didn't apply. This kept the original closing date intact instead of trading one delay for another while the buyer's team adjusted to the news.
The outcome
Once the buyer's own competition counsel confirmed the threshold analysis, the assumed waiting period came out of the closing schedule entirely. No filing was made, because none was required, and the weeks the buyer's deal team had set aside for it were freed up for the closing conditions that actually applied — financing, landlord consents for the clinic leases, and the transfer of clinical licences. The deal closed on the date the buyer had originally proposed, with no extension needed and no delay traced back to a regulatory step that, on proper analysis, was never on the critical path at all.
Amina, Anne and David sold their business for the price they had negotiated, on the schedule the buyer needed, and each received their share of the roughly $38 million purchase price according to their ownership stakes under the terms set out in the purchase agreement. David's practice management system, which had been called out separately in the deal's asset list, transferred with the rest of the business as part of the sale rather than becoming a point of last-minute negotiation. What could have been a deal remembered for weeks lost to an assumption nobody checked closed instead exactly when everyone expected it to.
The lesson for the family was not really about competition law at all. It was that a buyer's confidence about a regulatory step is not the same thing as that step actually applying, and a family selling a business for the first time has no easy way to tell the difference on its own. Checking the assumption cost a few days of analysis early in the process. Leaving it unchecked would have cost weeks the family did not have to spare against a buyer that had made clear its closing date was not moving.
What you can learn from this
- If a Canadian business acquisition might be large enough to require notice to the Competition Bureau before closing, check both the transaction-size and party-size thresholds against the actual numbers as soon as they're known — don't assume either way.
- A large buyer does not by itself make a transaction notifiable. Both thresholds have to be met, and it's the actual deal numbers, not the buyer's size or caution, that decide whether a filing is required.
- If a buyer's deal team assumes a filing is required, ask to see the threshold analysis rather than accepting the assumption — an unnecessary filing built into a closing schedule can cost weeks that were never actually needed.
- Sellers negotiating a closing date with a buyer should ask early whether any regulatory notice period genuinely applies to the deal, since an unchecked assumption in either direction can put a promised closing date at risk.
- When a family business includes assets built informally by one owner, like custom software, naming that asset explicitly in the purchase agreement avoids it becoming a late-stage argument once the deal is otherwise ready to close.
