Peace bonds really do apply any time a person fears on a reasonable ground that another person will cause personal injury, including to their spouse or child, or will damage their property. In cases where there is a pattern of behaviour that indicates certain types of risk, but insufficient evidence, let's say, to support a criminal charge, peace bonds can be a very useful tool. They can be sought by anyone. Their breach can be quite a serious criminal offence, including when that's repeated. There may be different views on how they could be used. In this particular context I don't disagree, but I do think it is an available tool, and an important one, given that in criminal law we of course have evidentiary issues and a very high burden to meet.
They are a very important safety tool.
