Be Informed about giving to Charities

Know the charity your giving a donation to!!!
If the Charitable status of that particular institution has been revoked or is under review you will loose your charitable tax credit.

Check out the cra website:https://apps.cra-arc.gc.ca/, by following the links to taxpayer information section you can find a link to the list of recently revoked and invoked charities.
All you need is the name of the charity or a general area in which it operates.
The CRA website will then present a listing. Remember in Canada the tax system is a self-assessment system, and it is the taxpayers responsibility to ensure that their proposed charitable tax credits come from creditable and legal sources.
