Glossary: N

A non-profit organization is an association, club, or society that is operated exclusively for social welfare, civic improvement, pleasure, recreation, or any other purpose except profit. It is not a charity. No part of the organization's income can be payable to or available for the personal benefit of any proprietor, member, or shareholder, unless the recipient is a club, society, or association whose primary purpose and function is to promote amateur athletics in Canada.

(CRA : Charities Glossary)

A non-qualifying security is, generally, a security where the owner of the security (e.g. a shareholder) is not at arm's length with the issuer of the security (e.g. a private company).  A charity can issue a tax receipt to the donor of a non-qualifying security in some circumstances.  The charity should get professional (legal, accounting or tax) help when someone intends to make this kind of gift.
