In the fall of 2009, the Saskatoon Freethinkers launched an atheist ad campaign. This campaign included a bus ad as well as a road side billboard. This message was a slight variation on a larger campaign elsewhere in the world, promoting various secular groups as a place for the non-religious. Dogma, and religious dogma in particular, is one of the greatest dangers to free and open inquiry and scientific literacy, and CFI Canada works hard to promote freedom from religion as a human right.
