Contrary to popular belief, spanking is legal in Canada. Many have tried to make spanking illegal in Canada, but never succeeded. You can read about the last failed attempt here.
Until recently, I have never viewed spanking as something bad when used reasonably. I, myself, grew up in a culture where spanking was allowed. But now, I’m finding myself moving towards the other end of the spectrum for one simple reason: abuse of power. Generally, adults don’t hit other adults even if they are angry. Why then should it be different for children?
