The Role of the Primary Parent in Ontario: Rights & Responsibilities
Does having the child the majority of the time give you the final say? Understanding the legal distinction between 'Primary Residence' and 'Sole Decision-Making'.
Legal Review: This custody guide was reviewed by Deepa Tailor, Senior Family Lawyer, to ensure compliance with the Divorce Act definitions of Primary Residence and Day-to-Day Decisions (2026).
What is a 'Primary Parent'?
In Ontario family law, a Primary Parent (or Primary Caregiver) is the parent with whom the child lives for more than 60% of the time. This status grants you the right to make 'Day-to-Day' decisions (e.g., bedtime, dinner, minor discipline) without consulting the other parent. However, it does NOT automatically give you the right to make 'Major Decisions' (e.g., changing schools, religion, or surgery) if you have Joint Decision-Making responsibility.
What Can You Decide Alone?
The 'Day-to-Day' authority explained.
Routine Discipline
You set the house rules, screen time limits, and chores while the child is in your care. The other parent cannot dictate your parenting style.
Emergency Medical
If the child gets sick or injured on your time, you make the immediate call to go to the ER or doctor. You must notify the other parent ASAP, but you act first.
School Logistics
You handle the daily forms, field trip slips, and homework supervision. (Note: Choosing the school itself is a Major Decision requiring consultation).
Social Activities
You decide on playdates and birthday parties that occur during your parenting time.
Does 'Primary' Mean More Money?
The 60% threshold changes the math.

The 'Set-Off' method applies (Lower amount).

How to Become (Or Stay) the Primary Parent
Establishing the Status Quo
The History of Care
Courts look at who did the work during the relationship. Who took maternity/paternity leave? Who scheduled dentist appointments? Evidence of past care predicts future custody.
The Separation Period
Where did the kids sleep the first month after you split? If they stayed with you, you have established a "Status Quo" of primary residence.
Availability
Can you handle school pickups and sick days? Primary parents often have more flexible work schedules.
Facilitating Access
Ironically, the best way to keep primary custody is to encourage the other parent's time. Courts punish "Gatekeepers" by reversing custody.
