When a Stepmother Fought to Keep a Child's Therapy Going

A missed mediation deadline looked like it had closed off every option for getting a child back into cancelled therapy sessions. A closer read of the separation agreement said otherwise.

The situation

Abena had already tried the calm approach. When her stepdaughter's anxiety spiked in grade six and a counsellor at the child's school recommended outside therapy, Abena and her spouse Teresa spent a month emailing Carmela, the child's other parent, proposing three different therapists and letting her choose. Carmela agreed to one, a psychotherapist not far from Ancaster who worked with preteen anxiety. The first four sessions went ahead without incident. Then, over about six weeks, Carmela cancelled three in a row - a work conflict once, a family visit once, no reason given the third time - each cancellation reaching the therapist's office with less than a day's notice.

Teresa tried talking to Carmela the way they usually worked through scheduling disagreements. That conversation ended with Carmela saying she did not think the child needed therapy at all and would decide, session by session, whether to bring her. Teresa and Abena then tried the process their separation agreement actually set out: a clause requiring the parents to attempt mediation before either one went to court over a disagreement about a significant decision for the child. They wrote to the mediator named in the agreement. But the agreement measured the window for requesting mediation from the date a dispute over the decision first arose - and by the time they wrote, that window had already closed. Nobody had realized the clock started running from the first cancelled session, not from the point weeks later when the pattern became unmistakable.

That was the state of things when the family came to our office: a child partway through a course of treatment for anxiety, a co-parent who had stopped bringing her, and the one contractual path to resolving it apparently already shut. Household income sat somewhere between ninety and one hundred forty thousand dollars a year, split between Teresa's work as a respiratory therapist and Abena's job managing a mid-sized office; they owned a mortgaged home in Ancaster and had pensions building slowly through their employers, but nothing in their finances gave them room to simply wait the problem out.

The therapist had already told them that inconsistent attendance was undoing progress the child had made in the first month of sessions, and that every further missed appointment made it harder, not easier, to get her re-engaged. Abena did not want to wait for a fourth cancellation to find out whether the fifth mediation letter would fare any better than the first.

The complication

The missed mediation window was a real problem, but it was not the only path available, and treating it as a dead end would have cost the family months. Under the Children's Law Reform Act, decision-making responsibility for a child's health care can sit with one parent, be shared, or be split by category, depending on what the parents agreed to or what a court ordered. Teresa and Carmela's agreement gave them joint decision-making on health and education matters generally, but it also said explicitly that once the parents agreed on a specific therapist and treatment plan, neither parent could unilaterally discontinue it without either the other parent's consent or a court order. That clause mattered more than the missed mediation window, because Carmela had not simply disagreed with therapy in the abstract - she had agreed to this therapist and this plan, then stopped honouring it on her own.

The mediation clause governed how new disputes about decisions got resolved before litigation. It did not erase the underlying agreement the parents had already reached about this child's treatment, and it did not give either parent a private veto over an agreement already in force. That distinction was the complication the family had not seen: they had been treating the missed deadline as though it barred them from doing anything, when in fact the deadline only affected how a fresh disagreement would be resolved, not whether an existing agreement could be enforced.

There was a second layer that made the file harder than it first appeared. Carmela's counsel, once retained, could reasonably have argued that discontinuing therapy was itself a new decision rather than a breach of the old one, and that any dispute about it therefore had to go back through the very mediation clause the family had already missed. If that argument succeeded, the family would be pushed back to square one, arguing about a closed window instead of about the child's care. Countering it meant being precise about the difference between disagreeing with a plan going forward and simply failing to follow a plan already agreed to - a distinction that sounds technical but decides which part of the agreement actually governs.

The other complication was practical rather than legal. Carmela's pattern of late cancellations, each one plausible on its own, made it hard to point to a single moment where she had clearly breached the agreement rather than simply had a difficult few weeks. We needed to document the pattern precisely enough that a court, if it came to that, would see a parent who had stopped participating in a plan she had agreed to, not a parent juggling ordinary scheduling friction. That meant assembling the therapist's cancellation log, the original email chain where Carmela chose the therapist, and a clear account of the harm the therapist had already flagged, before deciding whether litigation was even necessary.

What we did

  1. Reviewed the separation agreement clause by clause rather than relying on the family's summary of it, and found the distinction between the missed mediation window for new disputes and the standing obligation to honour a treatment plan the parents had already agreed to - the detail that reopened a file the family thought was closed off. Reading the full document ourselves, instead of trusting a stressed client's account of what it said, is what surfaced the clause the family had every reason to assume did not exist.
  2. Requested the therapist's session and cancellation record in writing, establishing a precise timeline of which sessions were cancelled, by whom, and with how much notice, so the pattern was documented in the clinic's own records rather than described secondhand from memory months later. Getting it directly from the clinic meant the timeline could not later be dismissed as the family's own recollection, and it gave us dates and notice periods precise enough to show a pattern rather than a run of bad luck.
  3. Pulled the original email chain where Carmela chose the therapist and confirmed the treatment plan, preserving the exact wording she had used to agree, since that agreement was the anchor for arguing this was enforcement of an existing decision rather than a fresh dispute subject to the missed mediation clause. Without that email, we would have been asking Carmela's counsel to take Teresa and Abena's word for what had been agreed, a much weaker position than pointing to her own written commitment.
  4. Anticipated the argument that discontinuing therapy was a new decision rather than a breach, and drafted our letter specifically to foreclose it, framing the request around Carmela's own written agreement to the plan rather than around whether therapy should continue at all. Naming and closing off that argument before Carmela's counsel could raise it meant the file could not get pushed back into the missed mediation clause, which would have cost the family months.
  5. Wrote to Carmela's counsel setting out the specific clause she had not honoured, attaching the cancellation record and the original email, and asked for written confirmation that sessions would resume on the existing schedule within two weeks. Putting the clause, the evidence, and the request in one letter gave Carmela's counsel everything needed to advise her quickly, rather than leaving room for a slow back-and-forth over what had actually happened.
  6. Set a short, explicit deadline for a response rather than leaving the request open-ended, because the family had already lost time to an ambiguous mediation window and could not afford another slow exchange of letters while the child's treatment sat stalled. A firm date signalled that the file was moving toward court regardless of Carmela's response, which is what ultimately pushed her counsel to engage well before the deadline arrived.
  7. Prepared a motion for a specific enforcement order in parallel with the letter, so that if Carmela did not respond, the family could go to court within days rather than starting the drafting process from zero after a deadline passed unanswered. Having the motion ready in advance meant the deadline in our letter was backed by something real, not an empty threat Carmela's counsel could safely ignore.
  8. Advised Teresa and Abena on what a motion would and would not achieve, making clear that a court could order the existing plan honoured and could address the pattern of late cancellations directly, but was unlikely to rewrite the decision-making clause itself, so their expectations matched what was realistically available before any deadline arrived. That honest framing kept them from either overselling the motion to themselves or panicking that it would fail to fix the immediate problem.
  9. Coordinated briefly with the therapist's office to confirm they would hold the child's slot rather than reassign it, so that a resolution reached through the letter or the court would not be undermined by a scheduling gap on the clinical side. Confirming this early meant a win on paper would translate into an actual appointment the child could return to immediately, rather than a further wait for the next open slot.

The outcome

Carmela's counsel responded four days before our deadline, agreeing to resume the existing schedule and confirming, in writing, that she would not unilaterally cancel further sessions without raising it through the parents' agreed process first. The motion we had prepared was never filed. The child returned to therapy having missed three sessions in total, and the therapist reported that the interruption had set back but not derailed the progress made in the first weeks of treatment.

The clear result was that the family avoided a contested motion that would have taken months to resolve and cost considerably more than the letter that ultimately worked. The cost was the three missed sessions themselves - a real setback the family could not get back, and one the therapist was candid about when the child returned. Nothing about the outcome erased that; it simply stopped the pattern from continuing.

Teresa and Abena also came away from the file with something more durable than the resumed schedule: a precise understanding of what their own agreement actually said, distinct from what they had assumed it said under stress. That distinction - between a deadline for raising new disputes and an existing obligation already in force - is easy to miss when a parent is reading their own separation agreement for the first time in a crisis rather than in the calm of a lawyer's office where it was drafted.

The file also closed faster than either Teresa or Abena expected once the right clause was identified. What had felt, in the weeks before they called us, like a slow-moving problem with no clear next step turned into a two-week exchange of letters once the argument was framed around an existing agreement rather than a fresh disagreement. That gap between how a problem feels and how quickly it can actually resolve is common in decision-making disputes: the emotional weight of a child care question makes every delay feel larger than the legal mechanics sitting behind it.

What you can learn from this

  • A missed deadline in one clause of a separation agreement does not necessarily bar you from enforcing a different clause that already governs the dispute - read the whole agreement before assuming a door is closed.
  • Once parents agree on a specific treatment plan for a child, that agreement usually cannot be unwound by one parent alone; a pattern of cancellations can amount to breaking that agreement even without a single dramatic refusal.
  • Document a pattern as it happens. A cancellation log and the original agreement email are far more persuasive, and far faster to assemble, than a memory of how things unfolded months later.
  • A firm, specific letter with a short deadline and a prepared motion behind it can resolve a dispute faster than an open-ended request for cooperation, without ever needing to file anything.
  • Interruptions to a child's care have real costs even when the dispute is ultimately resolved in your favour - a good outcome stops a problem from continuing, it does not undo the time already lost.
