We did have nuns in public schools when my dad and his brothers came to Northern Ontario from Montreal. But that was in the 1920s. I suppose they were still in schools for some time after that. My father liked telling the story about flipping a nun arse over tea kettle in the bowels of the school, all over an accusation and undeserved strapping. Three local boys ganged up on my dad, the new kid from Montreal, because he had nice clothes on. Appaerntly he beat hell out of them, too, and one of them retold the same story at dad's funeral. We couldnt believe it all those years.
