Exposure to Canadian Secular Education make the children of immigrants less prone to following the superstition of their parents.

You also give immigrants too little credit. Many have come to Canada to escape Theocratic oppression. They are eager to exert their Right to Freedom From Religion in Canada.

Sikhs in Canada bring tables and chairs into Temples, finding themselves slashed in the head (recorded on video) by the "Ceremonial" Kirpans of hardliners. Sort of like the Catholic reaction to Martin Luthor and other protestants.

Canada is being very slow about extraditing the conspirators who had a young woman killed after she refused to go along with family wishes about who she would marry. That is tied up with youth not falling for the Old Time Religion of their immigrant parents.
