You decide is it ethical to hit a child, or not to hit a child.
The Supreme Court of Canada has upheld a century-old law that allows parents, teachers and caregivers to spank children, but ruled the use of corporal punishment be confined to children between the ages of two and 12.
The top court had been asked to rule on whether spanking constitutes "reasonable force" for disciplining children, or whether it is a form of abuse. The court has heard arguments pro and con the efficacy of Section 43 of the Criminal Code, which allows parents, teachers and caregivers - including babysitters and foster parents - to use corporal punishment as "reasonable force" to discipline children.
