Fair enough. One of the purposes of having charities provide information and making it available on CRA's website is so Canadians who are donating to those charities can have information about their activities. How much do they spend on fundraising and certain administrative expenses? How much goes for other purposes? To the extent that they are engaging in political activities that are being funded from outside Canada, that may be information that donors will find informative in making decisions on how to donate.
