There are two ways.
First of all, there is this notion of activities that are made with, say, a “motive of gain”. Without getting into the details, it's an expression that has been used by the Supreme Court of Canada in analyzing and determining exactly what constitutes a charitable activity. We think that will clarify what is intended by that exemption in the act.
The second, and more important way—because this seems to be the biggest part of the problem relating to that exemption—is making it clear that merely acquiring charitable status, either for income tax or other purposes, or under statute, does not automatically make you eligible for this exemption.
