I think it might have been similar in Quebec
it was, until the 60s. Nearly overnight (in government terms, it was pretty quick, the changes into govt and society operated in the space of a decade)

), school & hospitals came back fully under the spell of the government. We had our own horror stories, and a government apology, with monetary compensation to the victims, often referred to as "Duplessis' orphans" for the name of the Premier most associated with the Church dominance on our life (though he wasn't the only one, only the one with the most vocal Church support - heaven is Blue [Conservative Party], hell is Red [Liberal Party] - they might have been unto something there, though...

).
Beatings and sexual abuse were pretty common for orphans give in the care of priests&nuns, but also for regular students at private colleges.
I believe some of the abuses persisted up to the 70s in some place, and I think I have heard forced adoption of First Nations children was still something in the early 70s (mother goes to the hospital, nurses secretly steal the baby and send it for international adoption, the mother is told the baby died but she can't see it because the remains have already been cremated). Religion mixed with a concept of White Christian superiority gave great results <sigh>.
My mom's brother was adopted, and he lacked oxygen at birth (that left sequels; huge behavioral sequels.). Due to his mother being pregnant out of wedlock, the Sisters caring for her were of the belief that she should suffer as much as possible to expiate her sins. That was pretty common in the 50s.
