The '20km Rule': Can I Move with My Child Without Permission?
Moving 15 minutes away is usually fine. Moving 45 minutes away can trigger a 'Change in Residence' court battle. Know the limits before you sign the lease.
Legal Review: This mobility guide was reviewed by Deepa Tailor, Senior Family Lawyer, to ensure compliance with the Divorce Act (Section 16.9) and Children's Law Reform Act regarding Relocation (2026).
Too Busy to Read? The 30-Second Answer
The Law:
There is no specific "20km Law" in the Divorce Act. However, most Separation Agreements include a "Radius Clause" (usually 20km or 50km) restricting where you can live.
The Test:
Even without a clause, you cannot move if it substantially affects the other parent's parenting time (e.g., makes school drop‑offs impossible).
The Notice:
Under the Divorce Act, you must typically give 60 days' written notice before any significant relocation.
The Risk:
If you move without consent, a judge can order the child returned to the original neighborhood immediately.
Minor Move vs. Major Relocation
The law treats a move differently depending on how far you go.
Change in Residence (Minor)
Moving to a new house 10 minutes away in the same school district.
Impact:
Low.
Requirement:
You must notify the other parent of the new address, but you usually do not need permission.
Relocation (Major)
Moving from Mississauga to Barrie, or even to the other side of Toronto during rush hour.
Impact:
High. It forces a change in the parenting schedule or school.
Requirement:
You NEED consent or a Court Order.
The 'GTA Traffic' Factor
In Ontario, distance isn't measured in kilometers; it's measured in 'Drive Time'.
The School Run Test
Scenario:
"Mom moves 25km away. The drive is 20 mins at night, but 60 mins during rush hour."
Legal Reality:
"If this makes it impossible for Dad to get the kids to school on his days, the court may block the move or force Mom to do all the driving."
The School District
Scenario:
"Dad moves 5km away, but it's across the boundary line for the child's French Immersion school."
Legal Reality:
"This is a 'Major Change.' You cannot unilaterally change the child's school. Dad may have to drive the child to the old school every day."
The Mandatory Notice Checklist
Under the Divorce Act, if you plan to move, you must provide a specific Notice of Relocation Form:
Timing:
Must be sent at least 60 days before the planned move date.
Content:
Must include the new address, contact info, and the proposed new parenting schedule.
The Objection:
The other parent has 30 days to object by filing a form. If they object, you CANNOT move the child until a judge says yes.
Common Moving Myths
The Myth
I Have Sole Custody
"I have Sole Decision-Making responsibility, so I can live wherever I want."
The Reality
Mobility is Separate
Decision-making is about choices (health, religion), not geography. Even with Sole Custody, you cannot move the child away from a parent who has access/parenting time rights.
