Here is a copy of a CRA Powerpoint presentation slide deck on the Regulation of Charities - Overview - September 2014. It provides some useful information including the CRA's audit plan. For example, the audit plan shows that CRA planned on auditing in 2014/15 32 registered Canadian amateur athletic associations (RCAAAs). That is a pretty large number as there are only 119 RCAAAs in total. Political activity audits in that same period only accounted for 2% of CRA audits. Only 4% of charities audited resulted in CRA issuing an notice of intention to revoke.
