Catholicism was always part of the separate school system, and was one of the things that distinguished them from the public boards. The teaching of religious based courses have always been a key component. Public boards have pretty much been secular institutions, and prayer was never a feature  of school life. Leave it to the Human Rights Commission, which has its reach far beyond its original mandate to interfere in this matter. If ever there was a government agency with virtually unlimited power, this is it.
