Canada’s Supreme Court has declined Husky Energy’s appeal over dividend withholding tax, upholding lower court findings that Luxembourg companies used in a share-lending arrangement were not the beneficial owners of the dividends.

The Supreme Court of Canada has dismissed Husky Energy Inc.’s application for leave to appeal on 3 September 2026. The decision upholds a 2025 Federal Court of Appeal ruling that blocked the company from using a tax treaty loophole to reduce withholding taxes on dividend payments. The outcome closes a significant chapter in Canadian tax litigation over beneficial ownership and treaty shopping.

The Luxembourg conduit structure

In 2003, Husky Energy declared a substantial dividend to its shareholders. Three Barbados-based corporations held more than 70% of the company’s shares. Each of these Barbados firms temporarily loaned its shares to Luxembourg corporations under standard Securities Lending Agreements. The Luxembourg companies received the gross dividend, then returned the shares to the Barbados firms along with the funds.

The Luxembourg tax authorities issued a ruling stating that the Luxembourg corporations were mere conduits for the dividends and bore no tax liability in Luxembourg. This arrangement appeared designed to exploit the lower withholding tax rate available under the Canada-Luxembourg treaty compared to the Canada-Barbados treaty.

The withholding tax dispute

Husky Energy withheld 5% tax on the dividends, citing the Canada-Luxembourg tax treaty rate applicable to Luxembourg residents. The Canada-Barbados treaty establishes a 15% withholding rate, while corporations without treaty coverage face a standard 25% withholding rate under Canadian law.

The Minister of National Revenue assessed the company for underpaying withholding taxes. The Minister’s position held that the Barbados corporations remained the beneficial owners and the 15% rate applied, regardless of the temporary share lending arrangement.

Court decisions and legal reasoning

The Tax Court of Canada examined the substance of the transaction rather than its form. The court found that the Luxembourg corporations assumed no financial risk and did not hold the dividends for their own benefit or use. Based on this analysis, the court determined the Luxembourg firms were not the beneficial owners and dismissed Husky Energy’s appeal.

The Federal Court of Appeal reviewed the Tax Court decision and found no errors in the beneficial ownership analysis. The appellate court confirmed that the Barbados corporations were the actual beneficial owners under tax law, making the 15% withholding rate the correct obligation.

Final outcome

Husky Energy’s attempt to reach the Supreme Court of Canada failed when the court dismissed the leave to appeal application. The dismissal leaves the lower court decisions final and binding. The ruling affirms that tax treaty benefits cannot be claimed through temporary conduit arrangements that lack genuine economic substance.
