A treaty exemption that let the buyer skip the clearance certificate

Anonymised, illustrative composite. One shareholder had emigrated years earlier, and the same shares were taxable Canadian property under one test and treaty-protected under another — the buyer closed on a notice filed after closing rather than a certificate obtained before it.

  • • Ontario, share purchase of a packaging-equipment distributor. One of three shareholders, holding 35% of the shares, had been resident in Colorado for nine years.
  • • The company sold its Milton, Ontario warehouse in a sale-leaseback 34 months before closing, when the building was roughly 61% of company value — inside the 60-month window ITA s.248(1) uses to test whether private-company shares are taxable Canadian property.
  • • By closing the company owned no Canadian real property. Article XIII of the Canada-US tax treaty taxes a gain on shares not real-property-heavy at disposition only in the vendor’s own country — treaty-protected property under s.248(1).
  • • ITA s.116(5.01) let the buyer skip the certificate: reasonable inquiry plus a notice within 30 days of closing satisfied s.116(5)(a.1), and the full $2,940,000 was released at closing.

The situation

A buyer agreed to acquire 100% of the shares of a specialty packaging-equipment distributor in Milton, Ontario. Three shareholders held the company: two Ontario residents, and a third who had moved to Colorado nine years earlier and had been non-resident for Canadian tax purposes ever since. Her 35% stake was priced at $2,940,000 of the $8,400,000 total consideration.

Thirty-four months before closing, the company had sold its own distribution warehouse in a sale-leaseback to fund an ERP rollout and inventory growth, at a price — $5,100,000 — that was roughly 61% of the company’s total value at the time. Since then it had leased the same building back and owned no Canadian real property at all. For the ordinary case, with no exception in play, see the vendor lived abroad, and the buyer that paid the full price without a certificate became liable for a quarter of it.

The problem

Diligence found two tests asking the same question at different points in time, with different answers. ITA s.248(1) paragraph (d) tests whether private-company shares are taxable Canadian property by looking back across the 60 months before disposition: “a share of the capital stock of a corporation… if, at any particular time during the 60-month period that ends at that time, more than 50% of the fair market value of the share… was derived… from… (i) real or immovable property situated in Canada” The warehouse sale sat 34 months back, at 61% — well over the 50% threshold. The shares were taxable Canadian property, full stop; the test does not care that the company no longer owns the building.

Article XIII of the Canada-US treaty asks a related question only once, at the moment of disposition, treating certain shares as real property: “(ii) a share of the capital stock of a company that is a resident of Canada, the value of whose shares is derived principally from real property situated in Canada” Every other gain falls to the residual clause: “Gains from the alienation of any property other than that referred to in paragraphs 1, 2 and 3 shall be taxable only in the Contracting State of which the alienator is a resident.” Nothing in Article XIII carries the ITA’s 60-month lookback — the treaty states no measurement period at all. By closing the company’s value was inventory, receivables and customer contracts; the warehouse was gone, and on the facts at disposition the gain fell to paragraph 4: taxable only in Colorado. That reading follows from setting the two texts side by side; no folio or case confirming it was located.

So the shares were taxable Canadian property under the ITA (34 months earlier) and treaty-protected under s.248(1) (at closing): “treaty-protected property of a taxpayer at any time means property any income or gain from the disposition of which by the taxpayer at that time would, because of a tax treaty with another country, be exempt from tax under Part I” Both true at once, and only one was about to matter to the buyer.

The numbers

$2,940,000 was the price for the departing shareholder’s 35% stake. Absent a certificate or an applicable exception, s.116(5) would have exposed the buyer personally to 25% of that — $735,000 — payable to the Receiver General within 30 days after the month of acquisition, out of the buyer’s own funds. An updated real-property appraisal and a treaty opinion confirming the paragraph 4 result cost $16,500.

The rule that decided it

s.116(5) gives three ways to avoid the 25% liability, and the third is easy to miss: “the purchaser, unless… (a.1) subsection (5.01) applies to the acquisition, or (b) a certificate under subsection 116(4) has been issued to the purchaser by the Minister in respect of the property, is liable to pay, and shall remit to the Receiver General within 30 days after the end of the month in which the purchaser acquired the property… 25% of the amount”

Paragraph (a.1) points to s.116(5.01), a notice in place of a certificate where the property would be treaty-protected: “the purchaser concludes after reasonable inquiry that the non-resident person is, under a tax treaty that Canada has with a particular country, resident in the particular country; (b) the property would be treaty-protected property of the non-resident person if the non-resident person were, under the tax treaty referred to in paragraph (a), resident in the particular country” — plus a third condition, that the purchaser actually sends the notice.

The notice is fixed by s.116(5.02): filed with the Minister, not obtained from the Minister, within 30 days after the acquisition, naming the vendor, the shares, the price and the treaty country: “the purchaser sends to the Minister, on or before the day that is 30 days after the date of the acquisition, a notice setting out (a) the date of the acquisition… and (e) the name of the country with which Canada has concluded a tax treaty under which the property is a treaty-protected property”

Read (5.01)’s two paragraphs separately. Paragraph (a) is qualified by “concludes after reasonable inquiry” — the same form as the residency defence elsewhere in s.116(5), protecting a genuine conclusion even if the fact later turns out otherwise. Paragraph (b) carries no such qualifier: whether the property “would be treaty-protected property” is a plain condition, true or false on the facts. Residency has a safety net; treaty-protected status does not.

A second route was set aside. s.116(6.1) makes treaty-exempt property “excluded property” under s.116(6) — but only where related parties also give notice. Unrelated parties, as here, never needed one at all. Counsel filed one anyway: a silent position leaves no record if the analysis is disputed.

The outcome

Closing proceeded on the full $2,940,000, with no escrow and no holdback. Counsel filed the s.116(5.02) notice eleven days after closing, giving the acquisition date, the shareholder’s name and Colorado address, a description of the shares, the price paid, and the United States as the treaty country. No s.116(4) certificate was applied for on this stake; the other two shareholders, Canadian residents throughout, closed without any withholding question at all.

What it would have cost otherwise

Closing without addressing s.116 would have left the buyer personally liable for $735,000 within 30 days of the month of acquisition. The certificate route carried a different cost: a s.116(4) certificate is applied for after the disposition and takes time to issue, ordinarily meaning a holdback until it arrives — cash tied up on a deal the parties believed created no Canadian tax at all. The residual risk under the notice route sat on paragraph (b) alone: had the appraisal found real property still over 50% of value at closing, s.116(5.01) would not have applied — because (b) does not ask whether the belief was reasonable.

The tell

The tell sat in the transaction history rather than the current balance sheet. Diligence that checks only what the company owns today finds no Canadian real property and moves on, never learning that a sale-leaseback three years earlier put the shares inside the ITA’s 60-month window regardless. The warehouse sale was a working-capital decision with no tax planning behind it, and it kept the s.116 procedural question alive for years after the exposure it once created had already gone.

Takeaways

  • • s.116(5)(a.1) and s.116(5.01)/(5.02) let a purchaser avoid the 25% withholding liability with a notice filed after closing instead of a certificate obtained before it — where the property would be treaty-protected.
  • • The ITA’s taxable-Canadian-property test (s.248(1)(d)) looks back 60 months; a treaty’s own real-property test for shares carries no equivalent lookback. A company can be domestically taxable Canadian property because of its history while the current disposition is treaty-protected.
  • • The residency conclusion under s.116(5.01)(a) carries a reasonable-inquiry defence. The treaty-protected-property conclusion under paragraph (b) does not — that is the real residual risk.
  • • s.116(6)/(6.1)’s excluded-property route can remove a property from s.116 entirely with no notice needed between unrelated parties — but it leaves no record with the Minister.

Published by the Department of Finance as a consolidated version “for convenience of reference only,” with no official sanction; the operative text is the Convention and its Protocols as ratified.
  • • Not confirmed by CRA guidance or a reported decision: that Article XIII’s real-property share test is assessed only at the time of disposition, with no equivalent to the ITA’s 60-month lookback. That reading follows from setting the two texts side by side; no folio or case addressing the point was located for this file.
  • • Treadstone Law — what a s.116 clearance certificate does and why it matters at closing — adjacent: written around a non-resident selling Canadian real estate directly, and covers the certificate route only. It does not address the s.116(5.01)/(5.02) notice alternative for treaty-protected property, which is the mechanic this file turns on.
