A Mennonite magazine, 'Canadian Mennonite', has received a warning from the Canadian Revenue Agency, about what articles and editorials it can publish, citing their pieces "appear to promote opposition to a political party, or to candidates for public office". That's a no-no under the rules for maintaining registered charity status.
Meanwhile, the Manning Centre, as previously reported, is an organization that exists solely to promote the Conservative Party and partisan Conservative activities within Canada. Yet, it continues to enjoy registered charity status with the tax agency.
So, regardless of what you think of this particular publication or the Mennonite Church's status as a charitable entity, the Canadian Revenue Agency still has to answer as to why the Manning Centre enjoys registered charity status.
