Parenting Arrangements in Ontario: Joint, Sole & Parallel Decision-Making Explained
Beyond "Custody" and "Access" — Understanding Modern Parenting Law
LEGAL STRATEGY REVIEWED
Legal Strategy reviewed by Deepa Tailor, Senior Family Lawyer. Updated January 2026 to reflect amendments to the Children's Law Reform Act and Divorce Act.
Too Busy to Read? The 30-Second Summary:
The Terminology: Ontario no longer uses "custody" and "access." We use "decision-making responsibility" (major choices) and "parenting time" (schedule).
The Test: Decisions are based 100% on the best interests of the child, not parental rights.
High Conflict: If communication is impossible, courts may order "parallel parenting" (divided authority) rather than joint decision-making.
The Language Shift: Why Words Matter
In 2021, Ontario modernized its family law language to reflect a child-centered approach. The old terms "custody" and "access" implied ownership and hierarchy. The new framework recognizes that children aren't property to be divided.
Old Term (Pre-2021)
Custody — Implied ownership
Access — Visiting rights
Joint Custody — Shared control
New Term (2021+)
Decision-Making Responsibility — Major choices
Parenting Time — Physical schedule
Contact — Time with non-parents
Key Takeaway: These changes aren't just semantic; they remove the concept of "owning" a child and focus on responsibilities and relationships.
The 3 Decision-Making Models
Understanding your options for major parenting decisions
Joint Decision-Making
Both parents make major decisions together
Both parents share responsibility for major decisions about the child's education, health care, religion, and extracurricular activities. This requires effective communication and cooperation.
Best For:
Parents who can communicate respectfully, live in proximity, and prioritize the child's needs over conflict.
Sole Decision-Making
One parent makes all major decisions
One parent has the authority to make all major decisions without consulting the other. The other parent typically still has parenting time but no decision-making power.
Best For:
Cases involving family violence, substance abuse, mental health concerns, or when one parent is absent or uninvolved.
Parallel Parenting
Decision-making authority is divided by domain
Each parent has sole decision-making authority over specific areas. For example, Parent A handles education and extracurriculars, while Parent B handles medical and religious decisions. This reduces the need for communication.
Best For:
High-conflict situations where communication is toxic but both parents are capable. This model allows disengagement while maintaining involvement.
High-Intent Keyword Alert:
"Parallel Parenting" is increasingly ordered in Ontario for families where joint decision-making causes more harm than good. It's a strategic alternative to sole custody battles.
LEGAL PRECEDENT
Sinclair v. Quade, 2018 ONSC 4342: The court ordered parallel parenting where the parents' inability to communicate was causing the child significant stress. Each parent was given exclusive authority over specific domains to minimize conflict.
What Factors Do Ontario Courts Consider?
All parenting decisions are based on the Best Interests of the Child test. Here are the key factors courts evaluate:
Important: Courts do not weigh parental "rights" or "fairness" to parents. The child's welfare is the sole consideration.

Addressing High Conflict and Family Violence
Safety is paramount. If you or your child are experiencing family violence, coercive control, or abuse, the court will prioritize protection over parenting time.
Ontario courts recognize that family violence isn't just physical. Emotional abuse, financial control, and threats are all considered when determining parenting arrangements.
What Courts May Order:
- Supervised parenting time at a designated facility
- No contact orders or restraining orders
- Sole decision-making to the protective parent
- Mandatory counseling or anger management
Evidence That Matters:
- Police reports and criminal charges
- Medical records documenting injuries
- Text messages, emails, or recordings
- Witness statements from family or professionals
Need Immediate Protection?
If you are in danger, you can seek an urgent safety order without waiting for a full trial. Emergency motions can be heard within days.
Parenting Time: Crafting a Workable Schedule
Parenting time refers to the physical schedule of when the child is with each parent. There is no one-size-fits-all approach.
Myth Buster
There is NO presumption of 50/50 time in Ontario. Courts do not start with equal time and work backward. Schedules are based solely on the child's best interests, considering stability, routines, and parental capacity.
Common Parenting Schedules
2-2-3 Schedule
Child spends 2 days with Parent A, 2 days with Parent B, then 3 days with Parent A. The pattern alternates weekly.
Best For:
Young children who need frequent contact with both parents. Requires parents to live close to each other.
Week On/Week Off
Child alternates full weeks with each parent. Exchanges typically happen on Sunday evening or Monday morning.
Best For:
Older children (10+) who can handle longer separations. Provides stability and reduces transitions.
5-2-2-5 Schedule
Parent A has Monday-Tuesday, Parent B has Wednesday-Thursday, then they alternate 5-day weekends.
Best For:
Parents with consistent work schedules. Each parent gets regular weekday and weekend time.
Primary Residence
Child lives primarily with one parent. The other parent has scheduled parenting time (e.g., every other weekend, one weeknight).
Best For:
When parents live far apart, or when one parent's work schedule is unpredictable.
Pro Tip: The best schedule is one that minimizes disruption to the child's school, activities, and friendships while maximizing quality time with both parents.
