Principal Issues: 1. Whether a stock option benefit realized by a US resident individual who performs part of his duties in Canada is subject to Canadian tax? 2. Whether, pursuant to paragraph 153(1)(a) of the Act, the non-resident employer of the US resident individual is required to withhold and remit Canadian tax on account of the US resident individual?
Position: 1. Not in this case. 2. Yes, unless a waiver from Canadian tax is obtained pursuant to section 102 of the Regulations. .
Reasons: 1. The stock option benefit is exempt from Canadian tax pursuant to the provisions of Article XV of the Canada-United States Income Tax Convention. 2. Even if pursuant to Article XV of the Treaty, the US resident employee’s remuneration (which includes the stock option benefit in respect of services provided in Canada) is only taxable in the U.S., paragraph 153(1)(a) of the Act and sections 101 and 102 of the Regulations, provide that the employer is required to withhold and remit Canadian tax on account of the US resident employee.
