A non-profit or charity most likely will be registered under
one of the Societies Act or the Companies Act, if under a provincial
act, or under Part II of the Canada Corporations Act, if federally
incorporated. But once the organization is registered, it needs
to maintain its status. This is done by filing a annual return
with either the provincial or the federal government, depending
on your incorporation statute. If not done, the organization
can be struck from the register. If that happens, the organization
doesn't legally exist. Notification about annual returns is sent
to the last known address. Make sure someone in the organization
knows that location.
