Many people thought it was UNWISE to create the Separate School Board -- done by a politician looking for votes in Ontario at the time.  Self-serving politics, as usual.  Quebec had a Catholic school system, but it got rid of it to ensure children were able to learn within a creative, questioning, and modern secular system, unencumbered by unsubstantiated old divisive beliefs that engendered a sense of 'indentured servitude' forced upon children who had to pledge devotion unquestioningly ... or fear 'eternal damnation', as a punishment forever. That is NO way to learn.  I think children should not be exposed to religion until they can think for themselves and are permitted to question the ideologies. Hence, no religion in schools, until a comparative course in high school that examines different contexts behind the old ideologies -- but such a course should not run longer than a term. There are other subjects & skills, including socialization, to learn first in early grades.
