If I bought and sold shares of a company during the same year and my income was all in payslips, do I have to indicate that I was business owner?

According to the Canada Revenue Agency (CRA), Buying and selling shares is considered a transaction of capital property - and so, it is seen to be reported as a capital gain/loss. Your income would still be reported through the T-Slips sections. So, the two would be reported separately in their own categories.
