A Clinic Sale Stalled By Cross-Border Tax Clearance

The situation

The letter arrived from the buyers' lawyer three weeks into the sale of Maricel's physiotherapy practice in Oakville, and it asked a single question that reset every plan she had made: could she confirm she was a resident of Canada for tax purposes at closing. Maricel had spent nine years building the incorporated practice from a single treatment room into a ten-person clinic, and eighteen months earlier she had moved abroad to be near her aging parents, running the business remotely through an office manager and regular calls with the clinic's referring physicians.

She had found buyers in Prakash and Gita, a married couple. Prakash was a plumber who wanted a hands-on business he could run himself, and Gita was an insurance adjuster who planned to manage the books and staffing. They had agreed on a purchase price in the upper part of the $750,000 to $2,000,000 range, financed partly through Prakash's trade savings and partly through a line of credit secured against the equity in their home. The deal itself was structured as a purchase of all the shares in Maricel's professional corporation, giving Prakash and Gita the clinic's equipment, the building it operated from, and its goodwill along with the corporate entity itself, while a small pool of pre-closing receivables was carved out and collected separately by Maricel under the purchase agreement.

What complicated the file was Maricel's residency. Because she had not filed a departure return or told the tax authority she had left Canada, she was, for the purposes of this sale, a non-resident vendor, even though she still held a Canadian bank account, still used a Canadian accountant, and still thought of Oakville as home. Because the corporation owned its clinic building outright and that real estate made up most of the company's value, the shares being sold counted as taxable Canadian property under the Income Tax Act, not merely a private company share sale that would otherwise fall outside the rule. That distinction mattered: a purchaser buying taxable Canadian property from a non-resident seller must withhold a substantial portion of the price and remit it to the tax authority unless the seller obtains a clearance certificate confirming any tax owing on the sale has been addressed. Without that certificate, Prakash and Gita's lawyer was obligated to hold back roughly a quarter of the purchase price rather than release it at closing.

Maricel came to us two weeks before the scheduled closing date, alarmed that a sale she had structured carefully with her accountant might see hundreds of thousands of dollars frozen indefinitely while a clearance application worked through a federal process with no guaranteed timeline. She needed the sale to close on schedule, because Prakash and Gita's financing commitment had its own expiry date, and she needed to understand exactly what the buyers were entitled to withhold and why.

What the other side was relying on

Prakash and Gita's lawyer was not being difficult. He was following a rule that exists precisely for situations like this one: a purchaser who fails to withhold from a non-resident seller can become personally liable for the tax the seller should have paid, up to the amount that should have been withheld. His position was simple and defensible. Until Maricel produced a clearance certificate, or the parties agreed on another way to protect the buyers, he would instruct Prakash and Gita to hold back a percentage of the price large enough to cover any reasonably possible tax liability, and he would not budge on that regardless of how inconvenient the timing was for Maricel.

He was also relying on the fact that the clearance application had not even been started. A certificate is not something a seller can request the week before closing; the application requires supporting calculations of the gain on sale, corporate financial information, and confirmation of the seller's tax filing history, and the tax authority's own processing takes months rather than weeks. From his chair, the math was straightforward: no certificate meant no early release of funds, and if Maricel's own advisors had not planned for the delay, that was not his clients' problem to absorb.

There was a second layer to his position. The statute gave him no room to accept a smaller holdback out of goodwill: absent a clearance certificate, the law required the purchaser to withhold twenty-five percent of the full purchase price, regardless of what Maricel's own accountant believed the true gain on the sale would turn out to be once her adjusted cost base was factored in. He could not agree informally to hold back a lower figure simply because Maricel's numbers suggested a smaller tax liability; only a certificate issued by the tax authority itself, specifying a lower amount, could change what he was legally required to withhold.

What he had not accounted for was that a clearance application, once properly filed with complete supporting documents, can sometimes be paired with an interim arrangement that lets a closing proceed on schedule while the certificate is still pending, provided the parties agree on how the holdback will be held and released. That possibility depended entirely on how quickly and how completely the application could be assembled, and on both lawyers agreeing to a structure that did not simply default to the standard percentage-of-price withholding.

What we did

1. Confirmed the non-resident status and its consequences by reviewing Maricel's departure date and her full Canadian filing history with her accountant, because getting the withholding calculation right depended on establishing exactly when her residency changed for tax purposes and what tax, if any, was actually owing on the sale, rather than accepting the worst-case gross-proceeds figure the buyers' lawyer had proposed as a starting position.
2. Assembled the clearance certificate application immediately, gathering the corporation's financial statements, a detailed calculation of the gain on the sale of the shares, and every supporting schedule the tax authority requires, so that filing could happen within days rather than weeks and the processing clock would start running as early in the transaction as possible. A complete first submission mattered because an incomplete package would have been returned for correction, restarting the clock on a process already running longer than the deal could comfortably absorb.
3. Negotiated an escrow structure with the buyers' lawyer that allowed closing to proceed on the scheduled date, with the disputed portion of the purchase price held by a neutral escrow agent rather than paid out to either side, which protected Prakash and Gita from any personal liability while still giving Maricel access to the undisputed portion of her proceeds immediately rather than months later.
4. Documented the release conditions precisely in the escrow agreement, specifying exactly how much would be released to Maricel once the clearance certificate issued, how much would go to the tax authority directly if any amount was ultimately confirmed owing, and what would happen if the certificate was delayed past an agreed outside date, so that neither party could later dispute what was supposed to happen.
5. Managed a family emergency mid-file when Maricel's father was hospitalized shortly after the application was submitted, requiring her to travel overseas and become largely unreachable for stretches of nearly two weeks; we adjusted our communication with her accountant and with the tax authority so that document requests kept moving without needing her immediate sign-off on every item. That adjustment kept the application progressing through a genuinely difficult stretch instead of stalling behind her unavailability, which would only have added more delay to a process already outside anyone's control.
6. Pushed for updates through the file's assigned examiner once contact was re-established, providing any additional information requested within days so the application did not stall behind a queue of less time-sensitive files, and kept Prakash and Gita's lawyer regularly informed so the escrow arrangement did not come under pressure to be renegotiated out of frustration at the delay. Steady contact with the examiner also meant we heard about the outstanding requirement before it became a missed deadline, rather than after.
7. Coordinated the final release of funds once the certificate issued, confirming the exact amount to be released against both the corporate records and the original purchase agreement, remitting the small confirmed tax amount directly to the authority, and closing out the escrow account with signed mutual releases from both sides of the transaction. Cross-checking the certificate figure against the escrow terms before releasing anything caught a rounding discrepancy early, so the file closed on the correct number the first time rather than needing a correction afterward.
8. Reconciled the numbers with Maricel's accountant after release, matching the certificate's confirmed figure against her original tax projections so she had a clean file to bring into her next filing year, and confirmed there were no residual reporting obligations tied to the sale that could surface as a surprise after the transaction had fully closed. That final reconciliation gave her something rare for a departing client living abroad: written confirmation that the sale was fully closed out, with nothing left to explain to a future accountant or a future auditor.

The outcome

The sale closed on the date Prakash and Gita's financing required, with the escrow structure holding back the statutory twenty-five percent of the purchase price the law required in the absence of a certificate, rather than leaving Maricel to negotiate an informal reduction the buyers' lawyer had no legal room to grant. Maricel received the undisputed balance immediately at closing, giving her access to most of her sale proceeds while the clearance certificate was still working its way through the federal process, and Prakash and Gita were able to take over clinic operations without any interruption to patient care or staffing.

The certificate itself took a little over four months to issue, longer than a typical file because of the interruption when Maricel's father was hospitalized and, not long after, passed away, which understandably slowed her ability to respond to document requests during a period that would otherwise have moved a good deal faster. Once the certificate arrived confirming that only a modest amount of tax was owing on the sale, the escrow funds were released almost entirely to Maricel, with a small portion remitted directly to the tax authority to satisfy the confirmed liability, closing the file with no dispute over the final numbers.

Prakash and Gita took possession of the clinic on schedule and were never exposed to personal liability for tax they had no way of assessing themselves, which was the exact risk their lawyer's caution had been designed to avoid from the start. Maricel, despite losing her father during the process, closed the sale she had spent nine years building toward and moved on from the business without an open tax exposure hanging over her, and without having to renegotiate price or terms to compensate the buyers for the delay. The escrow structure, rather than a standard blanket withholding negotiated under pressure, was what let both outcomes happen on the timeline the buyers' financing demanded, and it did so without either side having to absorb a cost that was not rightfully theirs to bear.
