We put conditions around the registration of charities, but the definition of a charitable activity has been established in common law and has evolved over the last 400 years. It includes care for health, poverty, education, and religion. It's really up to the hospital to determine whether it considers itself a charity, and in terms of the broader definition of what a charity is, hospitals clearly fall into that category.
For us to begin specifying that hospitals couldn't be considered charities would require a substantial change in the philosophy of how we define charitable purpose in Canada. It would be very difficult to do on a targeted basis just to deal with hospitals right now.
