A mental health diagnosis or a history of substance use does not, on its own, take away a parent's right to see their child. What matters to an Ontario court is whether a parent's current condition affects their ability to safely care for and make decisions for the child — not the diagnosis or label attached to it.
That distinction matters because these cases get emotionally charged fast, and it's easy for either parent to overstate or understate what's actually going on. This guide explains how mental health and substance use concerns typically factor into parenting time in Ontario, and what a restricted or supervised arrangement actually looks like in practice.
The Legal Test Focuses on Current Capacity, Not a Label
The best-interests-of-the-child test — used under both the Divorce Act and Ontario's Children's Law Reform Act — asks how a parenting arrangement affects the child's physical, psychological, and emotional safety, security, and well-being. A mental health condition or substance use history is relevant only to the extent it affects a parent's actual ability to care for the child day to day: supervision, judgment, consistency, and safety.
This means a parent who is in stable treatment, has a supportive routine, and has no pattern of impairment during parenting time is in a very different legal position than a parent whose condition is currently active, untreated, or has led to specific safety incidents. Courts look at current functioning and pattern, not just history or diagnosis in isolation.
When Concerns Can Lead to a Restricted Arrangement
A court, or the parents themselves by agreement, may restrict or add conditions to parenting time where there's a genuine, evidence-based concern about a child's safety. Family violence — including its impact on a parent's ability and willingness to safely co-parent — is an express factor in the best-interests analysis, and impairment-related risk can fall within that same lens when it creates a safety concern for the child.
Restrictions can take several forms, from least to most restrictive:
- Added conditions on unsupervised time, such as no use of substances during or immediately before parenting time
- Shortened or daytime-only parenting time rather than overnights
- Supervised parenting time, where another adult is present throughout
- In rare cases, a temporary pause on in-person contact in favour of other forms of contact, such as phone or video
Which of these applies, if any, depends entirely on the specific facts, and no outcome should be assumed from a general description like this one.
How Supervised Parenting Time Actually Works
Supervised parenting time means a neutral third party — a family member, a friend agreed to by both parents, or a professional supervision service — is present for the entire visit. The supervisor's role is generally to observe and, where a formal service is used, to keep a record of what happens during the visit.
Arrangements vary in structure: some specify a location, often a dedicated supervision centre, a set duration, and rules about what can be discussed with the child. Others are more informal, especially where the supervisor is a trusted relative rather than a professional service. Either way, the terms are usually spelled out clearly in the parenting agreement or order so there's no ambiguity about what's expected.
Moving From Supervised to Unsupervised Time
Supervised parenting time is generally meant to be a step, not a permanent state, though how and whether it changes depends entirely on the underlying concern and how it's addressed. A parent working toward expanded time typically needs to show:
- [ ] A sustained period of stability, not just a single good stretch
- [ ] Compliance with any treatment, monitoring, or testing conditions that were set
- [ ] Consistent, positive supervised visits over time
- [ ] Willingness to communicate constructively with the other parent
Because circumstances change, a motion to change is the standard process for asking a court to vary an existing order once there's evidence supporting an expanded arrangement.
Gathering Evidence Without Overreaching
If you're the parent raising a concern, courts expect specific, factual evidence — incidents, patterns, and their actual impact on the child — rather than general characterizations. If you're the parent responding to a concern, evidence of stability, engagement in treatment, and consistent, safe parenting time carries real weight.
Either way, this is an area where it's easy to do harm to your own case: exaggerating a concern, or minimizing a genuine one, tends to undermine credibility with the court. A lawyer can help you think through what evidence actually matters and how to present it.
Frequently asked questions
Does a mental health diagnosis alone mean I'll lose parenting time?
No. A diagnosis by itself isn't the test. What matters is whether your current condition and functioning affect your ability to safely care for your child, which is a very different question than whether you have a diagnosis at all.
Can I refuse to let the other parent see our child if I'm worried about substance use?
Not on your own judgment alone, in most cases. Unilaterally withholding parenting time can create legal problems for you even where your concern is genuine — the appropriate route is usually to raise the issue formally, through a lawyer, mediation, or the court, rather than self-help.
Who pays for a professional supervision service?
Costs and cost-sharing for a supervision service vary by arrangement and by provider, and aren't something this guide can generalize into a number — it's typically addressed directly in the parenting agreement or order.
Will a past substance use issue that's fully resolved still count against a parent?
Courts are generally focused on current capacity and pattern rather than a resolved past issue, but every case turns on its specific facts and evidence, so no general rule guarantees a particular outcome.
