I got a question for you: In 2004, the Supreme Court of Canada outlawed corporal punishment in all schools, public or private. The practice itself had largely been abandoned in the 1970s when parents placed greater scrutiny on the treatment of children at school. The subject received extensive media coverage, and corporal punishment became obsolete as the practice was widely seen as degrading and inhumane. Despite the fact that the tradition had been forgone for nearly 30 years, legislation banning the practice entirely by law was not implemented until 2004.
