If you are considering soliciting funds or other revenue sources, you'll need to look at what entity form you will need or could be beneficial. You may be able to qualitfy the entity as a not-for-profit either under the Federal or Provincial registrations but would need to research as the Federal statutes related to a not-for-profit have recently been tabled for new legislation and Provinces hve varying requirements including requirements for audits if revenues exceed some amount. Last time I read Ontario's legislation, the threshhold for an audit was $125,000 in gross revenues.
