Regardless of how anyone feels about this issue, it may be a moot point.  As the author stated, religious observance was a condition for confederation.  Religious schools and teaching further ended up as part of the constitution, with parts in both the 1867 and Charter of Rights and Freedoms.  While this article may be great for discussion on the place of religion in schools, there is little chance of change (constitutional change requires parliamentary action and at least 7 provinces for some matters and all 10 for others).  As a result of catholic school funding and recent court cases, Ontario taxpayer dollars are also going to other religious schools.
