Most of CRA’s view on political activities by Canadian charities can be found in Policy Statement CPS-022 Political Activities. (see Political Activities (CPS – 022) located at http://www.cra-arc.gc.ca/chrts-gvng/chrts/plcy/cps/cps-022-eng.html   I highly recommend that any charity considering conducting any activity that could be construed as political, review in detail the CPS-022 Policy Statement on Political Activities.

In addition, here are some other CRA policies, commentaries and information letters dealing with political activities that also provide some insight into CRA views and obligations of registered charities.
