From technical interpretation 2015-0579031I7:
Depending on the facts and circumstances, monies received by a taxpayer under a crowdfunding arrangement could represent a loan, capital contribution, gift, income, or a combination thereof. However, since the terms and conditions of these types of arrangements may vary greatly from one situation to another, the CRA’s approach is to evaluate each situation on a case-by-case basis before making a determination on the income tax consequences of a particular crowdfunding arrangement.
Notwithstanding the above, where funds are received by a taxpayer as a result of a crowdfunding arrangement for the development of a new product and that taxpayer carries on a business or profession, the CRA generally considers such funds to be taxable income (i.e., income from a source) unless it can be shown that the crowdfunding arrangement otherwise clearly represents a loan, capital contribution or other form of equity. Of course, any reasonable costs incurred by the taxpayer that are related to such a crowdfunding arrangement would likely be deductible in computing that income.
