Okay, back in the day Catholics were, believe it or not, highly ostracized in our society, this was during the time after Confederation when Irish immigrants were coming to Canada due to famine in Ireland. Ontario was, at the time, mostly Protestant. In 1867 Catholics were granted their own school board. Nowadays there isn't much prejudice demonstrated against Catholics, so it seems weird that their schools have funding and not other faiths. But Irish Catholics were severely discriminated against because of their faith, in fact all Catholics in Canada were discriminated against, there just were a lot of Irish Catholics so they got the brunt.
