I'm not an expert, but it would seem to be a big difference in that most peace bonds are entered into voluntarily in the Canadian court system. In other words, when someone asks for a peace bond, the other party comes into court and usually voluntarily agrees to it. In my experience with them, they are not always the result of an order that someone has refused to accept but are entered into voluntarily.
