In Canada, a registered charity must have a clearly-defined purpose that falls into at least 1 of 4 categories. These include 1. relief of poverty, 2. advancement of education, 3. advancement of religion, and 4. other tangible social benefits, such as environmental advocacy or health research. A charity can also fall into multiple categories (i.e. a homeless shelter with tutoring programs, a church that runs a food bank), if they form a significant portion of its activities.
