A practical guide to Ontario's mandatory charge policy in domestic cases, including why it exists, what reasonable grounds means, how officers assess the scene, and what families should expect after an arrest.

Urgent Notice

If you are in immediate danger, call 911.

If you need abuse-related support:

  • Assaulted Women’s Helpline (Ontario): 1-866-863-0511, TTY 1-866-863-7868, available 24/7 in over 200 languages
  • National Domestic Violence Hotline (U.S.): call 800-799-SAFE (7233), text START to 88788, or visit thehotline.org

Many people think a domestic charge only happens if the complainant wants it. In Ontario, that is not how the policy works.

If police attend a domestic incident and believe they have reasonable grounds that an offence occurred, charges may be laid even when both parties say they do not want anyone arrested.

What the Mandatory Charge Policy Means

Ontario’s policing standards direct officers to treat domestic violence as a public-safety matter, not as a purely private family dispute.

In practical terms, that means police are expected to act on evidence rather than leave the decision entirely to the people involved.

Why the Policy Exists

The policy grew out of decades of concern that domestic violence was being under-policed and minimized.

One of the recurring problems was that victims often faced pressure not to proceed. That pressure could come from:

  • fear of retaliation
  • financial dependence
  • children and housing concerns
  • extended family pressure
  • hopes of reconciliation

The charging decision was moved away from the complainant for that reason.

What Reasonable Grounds Means

Police do not need proof beyond a reasonable doubt at the scene. The standard is lower.

Officers may rely on:

  • injuries
  • damaged property
  • the 911 call
  • witness accounts
  • body-worn camera or other recordings
  • emotional state and demeanor
  • prior domestic call history

The question is whether the evidence would lead a reasonable person to believe an offence probably occurred.

What Officers Commonly Look For

At the scene, officers may assess:

  • visible injuries
  • torn clothing
  • broken objects
  • who appears frightened
  • who appears aggressive or controlling
  • statements made spontaneously
  • whether children were present

This is why charges can be laid even if someone later says it was “just a misunderstanding.”

Primary Aggressor Assessment

When both people make allegations, police are expected to look at who was the primary aggressor rather than automatically charging both.

That assessment may involve:

  • who initiated physical contact
  • whether one person was acting in self-defence
  • the comparative injuries
  • prior history
  • the overall pattern seen by officers

What the Policy Does Not Mean

The policy does not mean:

  • every allegation leads to conviction
  • police never make mistakes
  • the accused has no defence
  • the complainant’s views are irrelevant

It does mean the case enters the criminal system once officers believe the legal threshold has been met.

Why Charges Are Sometimes Laid Without Cooperation

Police do not always need the complainant to cooperate actively in order to lay a charge.

They may proceed on their own observations and the surrounding evidence. That is one reason people are often shocked after saying they did not want police action.

Immediate Consequences for Families

Once charges are laid, there are often fast-moving consequences, including:

  • arrest
  • release conditions
  • no-contact terms
  • exclusion from the home
  • disruption to parenting and finances

Those effects can be severe even before trial.

Rights and Immediate Next Steps

If you are arrested or questioned:

  • identify yourself where required
  • exercise your right to speak to a lawyer
  • do not try to talk your way out by giving a rushed statement
  • do not violate any release condition afterward

If you want to understand what happens once release conditions are imposed, read our guide to no-contact orders in domestic cases. If you are wondering why the complainant still cannot “drop the charges,” see our article on the Crown’s role in domestic cases.

Questions first-time buyers ask before closing

These are some of the most common questions people ask after police lay charges in a domestic call.

Do police need the complainant's permission to lay domestic charges?

No. If police have reasonable grounds to believe an offence occurred, they can lay charges regardless of the complainant's wishes.

What does reasonable grounds mean?

It means the officer has evidence that would lead a reasonable person to believe an offence probably occurred. It is more than suspicion but less than proof at trial.

Will police always charge both people if both make allegations?

Not necessarily. Officers are expected to assess who the primary aggressor was rather than automatically charging both.

Can charges be laid without visible injuries?

Yes. Police can rely on the totality of the circumstances, including statements, damage, witness information, and their observations.

What should an accused person do after arrest?

They should speak to a criminal defence lawyer immediately and carefully obey all release or bail conditions.
