The phrase “best interests of the child” has always been central to parenting disputes. What has changed is how courts are applying it.
Recent decisions from the Supreme Court of Canada, the Ontario Court of Appeal, and the Ontario Divisional Court reflect a more disciplined, evidence-driven approach grounded in the statutory framework under the Divorce Act and Ontario’s Children’s Law Reform Act.
Cases like Dunmore v. Mehralian, Diallo v. Bah, and Kirby v. Woods show that courts are moving away from broad discretion and toward a structured analysis of specific statutory factors.
1. Stability is no longer just a factor, it is often decisive
Courts have always considered stability. What is different now is the weight being placed on it.
In Kirby v. Woods, the court reinforced that where a child is thriving in an existing arrangement, that status quo carries significant weight. Disruption requires a clear, evidence-based justification.
This reflects a broader principle that children benefit from predictability. Courts are reluctant to introduce change simply because one parent proposes a “better” arrangement.
What this means in practice is that:
- A parent seeking change must show more than preference
- They must demonstrate a tangible benefit to the child
- They must overcome the presumption that stability should be preserved
2. Past conduct has become the strongest predictor of future parenting
In Diallo v. Bah, the court focused squarely on the parties’ historical conduct rather than their stated intentions.
This is consistent with a growing judicial skepticism toward forward-looking promises.
Courts are asking:
- Has this parent historically supported the child’s relationship with the other parent
- Has this parent complied with court orders
- Has this parent demonstrated consistency and reliability
Patterns of behavior now carry significant weight.
Examples that routinely influence outcomes:
- chronic lateness or missed parenting time
- failure to communicate or cooperate
- undermining the other parent
- exposing the child to conflict
3. Equal parenting time is not a starting point
Despite common assumptions, there is no presumption of equal parenting time under Canadian law.
In Dunmore v. Mehralian, the emphasis remained on the child’s needs rather than parental symmetry.
Courts will consider maximum contact, but only where it is consistent with the child’s best interests.
Key factors that often limit equal time:
- geographic distance
- parental conflict
- work schedules
- historical caregiving roles
The practical reality that equal time works best where parents already have a functioning cooperative relationship.
Where that does not exist, courts prioritize practicality over equality.
4. The statutory factors are being applied more rigorously
Courts are increasingly grounding their decisions in the specific statutory factors set out in legislation.
These include:
- the child’s needs and stage of development
- the strength of relationships with each parent
- each parent’s willingness to support the other relationship
- the history of care
- family violence, where applicable
Judges are not just referencing these factors. They are systematically working through them.
This results in:
- more predictable outcomes
- less reliance on subjective impressions
- greater emphasis on evidence
5. The child’s lived experience is central
Perhaps the most important shift is the focus on the child’s actual experience.
Courts are asking:
- What does this child’s daily life look like
- What is the emotional environment
- How is conflict affecting the child
This moves the analysis away from parental rights and toward child impact.
Bottom line
The modern approach to parenting disputes is clear:
- The status quo matters
- Conduct matters
- Evidence matters
Parents who approach litigation as a debate about fairness between adults are missing the point.
The court is not deciding what is fair to you. It is deciding what works for your child.
