Yes. In fact, depending on the extent of your actions, you may be engaged in business activity in the eyes of the CRA and will be taxed accordingly. Both mining (i.e., creating new crypto to enter into circulation) and staking (earning rewards as a result of holding certain types of cryptocurrency) will be considered taxable income by the CRA. Whether or not the crypto earnings generated from mining or staking will be considered business income or capital gains will be evaluated on a case-by-case basis. Both methods of engaging in cryptocurrency are historically used to generate passive income, which will always be taxed.
