16 in Ontario?  Seriously?  Well I guess we're bad parents and going to jail .... ours was left alone at home as of age 10.

Fortunately .... Ontario's rules aren't quite as draconian as they seem. Under age 16 you can leave them alone if you've made provision for their supervision and care that is reasonable in the circumstances.

Our daughter is mature enough that she is provided with supervision and care that is reasonable in the circumstances.
