Do you even understand the Canadian legal system?
Monika Caryk will not be charged with anything. She is not under investigation as of today for anything. There is no criminal investigation when someone is applying for a protection order. The Karlsson's filed a protection order against Caryk. In court, the Judge ruled there was enough evidence to go ahead with the order, and serve it to Caryk. A protection order just means that Caryk is being legally warned not to contact the Karlsson's.
If Caryk deliberately breaks the protection order, she runs the risk of being charged (my guess would be contempt of court) with a criminal offense. That fact that the Karlsson's went with a P.O. instead of trying to charge Caryk with harassment (assuming there was enough evidence to do so), may indicate a desire to warn the person in question to leave them alone, without having the headache of making court appearances, if they were to try and bring any kind of criminal charges.

This happens quite a bit in Canada, especially in regards to domestic incidents.
