A peace bond made in BC can be enforced by police anywhere in Canada. Visit the police in your new province or territory, show them a copy of the peace bond, and tell them about your situation. Through a Canada-wide computer system, the police in any province or territory can check the conditions in the peace bond and enforce them.
There is also a process to register the order in other provinces or territories if the person who has the order against them moves to another area of Canada.
