One other thing: the public system arose out of the church of England schooling. Most community schools were attached to the predominant religion in the community which was generally but not always Anglican. The Methodists were quite predominant as well. Wasn't a problem because most of our communities were based around the local church: the two grew together. It was Ryerson that standardised the education system in Ontario but he didn't do it with the intent of abolishing the link between the school and the church; that came much later. If you find the school readers from before 1960 or so you will quickly find that stories from the Bible were an integral part of the curriculum. Also, as an aside, the vocabulary was a lot richer than it is now and standards were significantly higher. Pick up a copy of a novel from the 19th century from authors such as Dickens or Walter Scott. I doubt if you will get through the first chapters without having to resort to a dictionary
It is interesting that you refer to Ryerson, the Methodists and the Church of England.
Those are the basic elements of the Upper Canada Rebellion of 1837.
The Church of England was the Established church of the state.
It is the church-state relationship referred to in the US first amendment.
To be an officer of the state you had to be a member of the Church of England. This automatically excluded Catholics.
But it also excluded protestants that were variously described as separatists, dissenters and non-conformists. These included Quakers, Baptists, Moravians, Unitarians, Deists and Atheists. They also included Presbyterians and Methodists.
In Upper Canada in 1837 the Crown had set aside land for churches and schools. The local Church of England Bishop, a Scotsman name of Strachan (variously pronounced) held that all those lands were solely for the use of the established church and were denied to dissenters like the Methodists. Egerton Ryerson was a Methodist who wanted to establish schools.
He was supported by a radical Scots pamphleteer name of William Lyon Mackenzie, recently immigrated from Scotland, and as such a Presbyterian, and by the members of another Scottish import, the Mechanics Institute, essentially a night school for tradespeople, men and women, that was funded by fees, subscriptions and donations. They started in Glasgow during the French revolution.
Ryerson was kicked out of his C of E house at 17 by his father for becoming a Methodist. In Upper Canada Methodism was associated with Americanism.
Ryerson, his Methodists, mechanics and Presbyterians, wanted some of Strachan's tax free church lands for their own schools. Strachan was as tight-fisted as any and he was backed by the local Establishment, the Family Compact.
Meanwhile the Presbyterians had a different set of beefs.
The Church of England ran with bishops appointed by the Crown.
Scotland fought England for the best part of 200 years to prevent that happening in Scotland. Since 1560 Scotland had been Geneva School Presbyterians. They would have no bishops, especially bishops appointed by a crown, let alone a foreign crown. That was the crux of their argument against both English and Papal bishops. The Scots demanded the right to hire and fire their own ministers at the parish level and decide for themselves what they could read, what they could believe, what they could say and print, and what they could teach their kids. They co-operated between parishes using a pyramid of group meetings, elected representatives and moderators. There was no permanent central authority. But this structure formed the Scottish Establishment. And to be an officer of the state in Scotland you had to be a Presbyterian and foreswear bishops.
In 1707 the Scots Establisment united with the English Establishment. Anti-Episcopalian Presbyterians were forced to come to terms with Anti-Presbyterian Episcopalians. The simple solution was to for the Crown to recognize Presbyterians in Scotland and Episcopalians in England. All others need not apply although they could go to their own churches in peace.
The problem arose outside of Britain. In Ireland, Newfoundland, America and Canada. Under the joint crown which establishment was to be recognized. The English said the Episcopalians. The Scots were disagreeable.
Ultimately this was the cause of the grief in Ireland and America. And in Canada. The English claimed all the offices and privileges on the grounds of being Established Episcopalians and denied them to the Scots Presbyterians. This drove the Presbyterians out of Ireland to America. They became no more gruntled in America.
Concurrently the Wesley Brothers were organizing a working class revolution - church for tradesfolk. People getting together and singing new songs praising God and Jesus to old tunes they sang at the pubs.
They took trade away from the Establishment church and thus were denied offices.
They actually got their start in the Utopian colony of Georgia, founded and governed by another Scot name of Oglethorpe. The colony was founded as a refuge for the poor and a military barrier against the Spanish in Florida. It was also explicitly opposed to slavery as long as Oglethorpe was governor.
So the Methodists and the Presbyterians had a joint reputation as radicals. And they cost the English Establishment America and made life miserable for them in Ireland by siding with the Americans, the revolutionary French and the local Catholics.
So Strachan wasn't having any of that nonsense in his Canada.
Mackenzie and Ryerson were of contrary opinion. Their side got a boost with the British Reform acts of the 1820s and 30s which opened public offices to all dissenters, Catholics and even Unitarians and atheists. All they had to do was swear allegiance to the Crown.
The rebels lost the battle but Strachan lost the war.
And thus you have the basis for the modern compromise on religion and education in Canada.
And the demand for separation of church and state in the US.
No laws concerning the establishment of religion.
Nothing to prevent people believing and professing, even Islam or Catholicism. Toleration is the byword. But religion could not be used as a litmus test for public office.
