The CRA has released recently the 2019 version C of its T3010 Registered Charity Information Return. The major changes deal with replacing political activities with "public policy dialogue and development activities" (PPDDAs). As a result of Finance's 2018 changes CRA no longer asks for much information on "public policy dialogue and development activities". CRA asks whether your charity did PPDDAs and give you a paragraph to describe the PPDDAs and how they relate to your purposes but don't ask how much you spent on them. So when a billionaire's foundation spends $500 million on this type of political activity - you probably will not be able to easily detect it. Remember we are all created equal - some are just more equal than others. In fairness to billionaires, it was not billionaires asking for this change - it was mainly a few progressive groups.
