The Consequences of Relocating With a Child Without Proper Notice in Ontario

Ontario's family law framework gives a parent a specific process to follow before moving a child away from the other parent: written notice, given in advance, in the proper form. Skipping that process — moving first and explaining later — is one of the more damaging mistakes a separated parent can make, even when the move itself might otherwise have been reasonable.

This guide covers what can actually happen, legally and practically, when a parent relocates with a child without following Ontario's notice rules.

The Notice Rule You're Expected to Follow

A parent, or anyone else who holds parenting time, decision-making responsibility, or a contact order, who plans to relocate a child generally must give written notice, in the prescribed form, to everyone else who holds parenting time, decision-making responsibility, or contact. For parents divorcing under the federal Divorce Act, that notice must be given at least 60 days before the move — as of mid-2026, and worth verifying against the current requirement, since this kind of figure can change. Ontario's Children's Law Reform Act contains a comparable notice obligation for unmarried parents; confirm the period that applies to your situation rather than assuming it matches exactly. The only recognized exception is where a court excuses someone from giving notice because notice itself would create a significant risk of family violence.

What the Other Parent Can Do Right Away

Once a parent discovers a move happened, or is about to happen, without proper notice, their options typically include:

• Bringing an urgent motion asking the court to address the move immediately, which can include a request to return the child pending a full hearing
• Asking the court to enforce or clarify the existing parenting order in light of the unauthorized move
• Seeking a formal variation of decision-making responsibility or parenting time to reflect what's happened

None of these outcomes is guaranteed — the court still applies the best-interests test — but the parent who moved without following the rules starts the conversation from a weaker position.

How It Can Affect Decision-Making Responsibility and Parenting Time Long-Term

Beyond the immediate response, an unauthorized move can influence how a court views that parent going forward. Courts consider a party's conduct — including whether they respected the other parent's role and followed required processes — as part of the broader picture when assessing what arrangement truly serves the child's best interests. A pattern of ignoring notice obligations, or of making unilateral decisions that cut the other parent out, can weigh against a parent seeking expanded decision-making responsibility or a more favourable schedule later.

Other Practical Consequences

• Credibility. Family court is rarely a one-time event for separated parents — it often involves an ongoing relationship with the same court, and sometimes the same judge, over time. Undermining trust early can have a lasting effect on how future requests are received.
• Cost exposure. Ontario courts have general authority to make cost awards against a party based on how a case was conducted, including conduct that caused unnecessary urgency or expense — though outcomes vary case by case and shouldn't be assumed.
• Strained enforcement. Depending on how far the move went, getting the situation unwound — especially where distance or a border is involved — can be far more difficult than it would have been to simply follow the notice process in the first place.

The Family Violence Exception Is Narrow

It's worth being precise here: the exception to giving notice exists specifically where there's reason to believe that giving notice would create a significant risk of family violence — not as a general escape hatch for a parent who simply expects the other parent to object or make things difficult. Relying on this exception without a genuine, supportable basis is a decision worth making with legal advice, not alone.
