The Importance of an Age-Appropriate Parenting Plan: Why Ontario Courts Are Looking to Evidence-Based Guidance

When parents separate, one of the most significant decisions they must make concerns the future care of their children. A parenting plan is far more than a schedule—it is the framework that supports a child’s stability, emotional security, and healthy development following separation.

Too often, parenting arrangements are proposed based on convenience, conflict, or generalized assumptions rather than the specific developmental needs of the child. What may be suitable for a teenager may be entirely inappropriate for an infant or preschool-aged child. For this reason, developing an age-appropriate parenting plan is critical.

Across Ontario, courts, lawyers, and family justice professionals increasingly look to the AFCC-O Parenting Plan Guide as an important evidence-based resource when assessing parenting arrangements.

What Is an Age-Appropriate Parenting Plan?

An age-appropriate parenting plan is one that reflects a child’s developmental stage, emotional needs, routine, temperament, and ability to transition between households.

Relevant considerations include:

• the child’s age and maturity;
• attachment relationships and caregiving history;
• school and extracurricular obligations;
• emotional regulation and adaptability;
• sibling relationships;
• communication with each parent; and
• the child’s ability to manage separations and overnight time.

A parenting plan should evolve as a child grows. A static or generic schedule may fail to meet a child’s changing needs over time.

Why Standardized Parenting Schedules Often Create Problems

Many parents begin by searching for “50/50 schedules” or common parenting templates online. While these arrangements may work in some circumstances, they are not universally appropriate.

Infants and Young Children

Younger children often benefit from frequent, consistent contact with both parents, while long absences from either parent may be developmentally challenging.

School-Aged Children

Children in school typically benefit from greater routine, educational consistency, and schedules that support peer and extracurricular commitments.

Teenagers

Older children often require increased flexibility and greater input into parenting arrangements due to academic, employment, and social responsibilities.

Poorly designed parenting plans can increase conflict, create instability, and lead to unnecessary litigation.

The AFCC-O Parenting Plan Guide

The Association of Family and Conciliation Courts – Ontario Chapter (AFCC-O) developed the Parenting Plan Guide to assist parents, counsel, mediators, and courts in creating child-focused parenting arrangements informed by modern social science.

The guide addresses:

• child attachment and developmental needs;
• the impact of parental conflict on children;
• shared parenting research;
• transitions between homes;
• age-specific parenting considerations; and
• practical planning tools for parents.

Ontario Courts Are Increasingly Recognizing the Guide

In Tremblay-Chartier v. Blanchette, 2025 ONSC 6273, the Ontario Divisional Court confirmed that while the AFCC-O Parenting Plan Guide is not binding law, it is a significant and persuasive authority grounded in accepted social science.

The Court held that where a parenting order departs from the guide’s evidence-based recommendations, judges should provide reasons for doing so. The decision reflects the growing judicial recognition that the guide summarizes consensus research regarding child development and parenting after separation.

This is particularly important in cases involving younger children, where developmental considerations and attachment needs often require careful analysis.

The practical takeaway is clear: parenting proposals that align with recognized child development principles are increasingly persuasive, while schedules unsupported by evidence may face greater scrutiny.

Why This Matters for Parents

Parents involved in negotiation, mediation, or litigation should understand that parenting decisions are no longer based solely on competing preferences. Courts are increasingly focused on evidence-based outcomes that advance the best interests of the child.

A properly structured parenting plan can:

• reduce parental conflict;
• promote stability for children;
• improve the likelihood of settlement;
• strengthen a court application or defence; and
• reduce future returns to court.
