In this article entitled “Partial Glimpse at 2013 T3010 Filings Dealing with Political Activities by Canadian Registered Charities” I discuss the 51,000 Canadian registered charities have had their T3010 for 2013 added to the CRA database so far.   This 51,000 represents about 60% of registered Canadian charities. In a partial glimpse of the 2013 T3010 information about 333 of 51,000 charities reported so far carrying on any political activities during their 2013 fiscal year, whether by volunteer, staff or spending.  A similar number also said they spent money on political activities. 

As I note in the article these numbers are probably quite inaccurate.
