The most important document for Canadian registered charities to understand their obligations for fundraising is the CRA’s Fundraising Guidance.  You can see the document in English at:  http://www.cra-arc.gc.ca/chrts-gvng/chrts/plcy/cps/cps-028-eng.html and in French at:
http://www.cra-arc.gc.ca/chrts-gvng/chrts/plcy/cps/cps-028-fra.html To make it more convenient for some the Charity Law Information Program (CLIP), which is supported in part by funding from the Canada Revenue Agency, has taken the main document and inserted the content of the “Additional Information” directly next to the part of the Guidance it is referring to. A reader can read the guidance from beginning to end without having to jump backwards and forwards between the two documents. The CLIP version of Fundraising Guidance is at: http://www.capacitybuilders.ca/files/resources/CRA_Fundraising_Guidance_1259599283.pdf
Whatever version you wish to use – this is a guidance document that anyone involved in governance and fundraising of charities should review.

Another interesting guidance is from the Ontario Public Guardian and Trustee entiteld “Charitable Fundraising: Tips for Directors and Trustees”
