Investing

Stock Option (Employee Stock Option / ESO)

The right — but not the obligation — to buy a set number of company shares at a fixed price (the strike or exercise price) for a defined period after vesting. If the share price rises above the strike, the option has value; if not, it expires worthless. In Canada, the spread between strike and market price at exercise is taxed as employment income, often with a 50% deduction available on eligible options (the Canadian Controlled Private Corporation rules and the $200,000 annual cap on the deduction add complexity). The decision of when to exercise — and whether to hold or sell the resulting shares — drives both the tax bill and the concentration risk.
