Can I Stop My Ex From Contacting Me After Separation in Ontario?

TSL Written by the Treadstone Law Team· Updated November 13, 2026

Yes, there are options, and which one fits depends on how serious the contact is and whether you feel unsafe. If you are in danger, call 911 or local police immediately. In less urgent situations, a short, calm written message that states your boundary and keeps a copy can be a reasonable first step.

In family court you can apply for a restraining order if you are worried about your own or your children's safety and you were married to or lived with the person for any period of time, or have a child with them. The order can limit where the person goes and who they contact, such as keeping a set distance from your home, workplace or your child's school. A peace bond is a criminal court order that can be in place for up to one year and can be renewed if fear continues, and breaking it can lead to a criminal charge.

Getting into an ex's email or social media accounts fraudulently and without colour of right can be an offence. The Victim Support Line is 1-888-579-2888. A lawyer can help you choose between these options.
