Definition
In Canada, the tax treatment of Bitcoin mining hinges on whether the Canada Revenue Agency (CRA) views the activity as a business or a personal hobby. The distinction is significant: business mining income is included in taxable income at 100%, while a hobby is treated differently and cannot deduct expenses. This is general information, not tax advice; your classification depends on your specific facts.
Business or hobby?
The CRA decides on a case-by-case basis, weighing factors such as profit intent, the scale and regularity of the operation, dedicated equipment, and businesslike conduct. A casual setup with a single machine and little earnings may be a hobby, whereas a sustained, profit-seeking operation with multiple rigs and ongoing electricity costs typically looks like a business.
How business income works
If mining is a business, the fair market value (in CAD) of the coins at the moment you receive them is business income for that tax year. That same value becomes the adjusted cost base of the coins, so a later sale is a separate disposition measured against it. The upside of business treatment is deductibility: hardware (often via Class 50 capital cost allowance), electricity, hosting, repairs, and a reasonable share of overhead can reduce net income. Hobby miners get no such deductions.
Because the rules are nuanced, our Bitcoin mining tax guide walks through both paths in more depth, but a qualified Canadian accountant should confirm your treatment before you file.
