To calculate the ACB of your eligible securities, add the following two amounts:

• the actual purchase price
• any amount included in your income as a taxable employee option benefit for the securities (even if you claimed a security option deduction for them)

Your proceeds of disposition are what you sold them for.

If you acted on this stock option, the proceeds of disposition would be $6,000 and the adjusted cost base would be $5,000.
