U.S. Income Tax Treaty — Canada Technical Explanation - 1980 · 2026-10-03 edition · updated 2026-10-04 · United States

Paragraph 1 of Article XIII of the Convention provides that gains derived by a resident of a Contracting State from the alienation of real property situated within the other Contracting State may be taxed in that other State. The term “real property situated in the other Contracting State” is defined for this purpose in paragraph 3 of Article XIII of the Convention.

Under paragraph 3(a) of Article XIII of the Convention, real property situated in the United States includes real property (as defined in Article VI (Income from Real Property) of the Convention) situated in the United States and a United States real property interest. Under section 897(c) of the Internal Revenue Code (the “Code”) the term “United States real property interest” includes shares in a U.S. corporation that owns sufficient U.S. real property interests to satisfy an asset-ratio test on certain testing dates.

Under Paragraph 3(b) of Article XIII of the Convention, real property situated in Canada means real property (as defined in Article VI of the Convention) situated in Canada; shares of stock of a company, the value of whose shares consists principally of Canadian real property; and an interest in a partnership, trust or estate, the value of which consists principally of Canadian real property. The term “principally” means more than 50 percent.

Under the Code, stock of a foreign corporation is not considered a “United States real property interest.” Therefore, the United States does not tax a resident of Canada on the sale of stock of a foreign corporation, regardless of the composition of the corporation’s assets. Although the Convention permits Canada to tax a U.S. resident on the sale of stock of a company that is not a resident of Canada if the value of the company’s shares consists principally of Canadian real property, Canada does not currently impose such a tax. However, on April 26, 1995, amendments were proposed to the Canadian Income Tax Act that would impose Canadian income tax on gains realized on stock of certain companies that are not residents of Canada if

(i) more than 50 percent of the fair market value of all of the company’s properties consists of any combination of taxable Canadian property, Canadian resource property, timber resource property in Canada and income interests in Canadian trusts, and

(ii) more than 50 percent of the fair market value of the shares in question is derived directly or indirectly from any combination of real property located in Canada, Canadian resource property, and timber resource property in Canada.

This amendment is proposed to be effective as of April 26, 1995 with proration for gains that accrued before that date. Although the Canadian Parliament was dissolved before these amendments were passed, they are expected to be re-introduced in the current session with the same effective date.

The Protocol amends paragraphs 3(a) and 3(b)(ii) of Article XIII of the Convention to limit each State’s right to tax the gains of a resident of the other State from the sale of stock of a real property holding company to cases where the company is resident in that State. Although the United States does not impose and is not currently considering imposing a tax under the Code on gains from the sale of stock of nonresident real property holding companies, the Protocol nevertheless amends the Convention to prohibit the imposition of such a tax on Canadian residents. Although Canada is considering imposing such a tax on gains from the sale of shares of companies that are not residents of Canada, this Protocol provision will cause the proposed amendments to the Canadian Income Tax Act to be inapplicable to U.S. residents who derive gains from the sale of stock of real property holding companies that are not residents of Canada. This provision will be retroactively effective to April 26, 1995, the date the previous Canadian legislation was proposed to be effective.
