Information for security holders outside Canada

Cash dividends paid to shareholders resident in the United States are, under the Canada-US income tax convention, subject to a Canadian non-resident withholding tax of 15 percent.

The withholding tax is reduced to 5 percent on dividends paid to a corporation resident in the U.S. that owns at least 10 percent of the voting shares of the company. The rate of withholding applicable to other jurisdictions may vary.

The company is a qualified foreign corporation for purposes of the reduced U.S. capital gains tax rates, which are applicable to dividends paid by U.S. domestic corporations and qualified foreign corporations.

There is no Canadian tax on gains from selling shares owned by non-residents not carrying on business in Canada, as long as the shareholder does not, in any given 60-month period, own 25 percent or more of the shares of the company.

Canada has approved several positions with respect to the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting("MLI"), which may impact the taxability of dividends and capital gains in Canada if the shareholder’s country of residence has also approved these same positions of the MLI.
