The situation
David spent nearly three decades building and then selling a manufacturing supply business, retiring in his late fifties with a comfortable cushion of savings and investments. His spouse, Tom, ran a construction company he had grown from a two-person outfit into a firm with a steady roster of residential and light commercial contracts. Between the sale proceeds, the construction business, a home in Peterborough, and a rental property they had bought together, the couple's combined family property sat somewhere between $1 million and $4 million. They had been together twenty-two years and had one son, Raymond, sixteen years old.
Eighteen months before David came to Treadstone Law, he had a stroke. He recovered well by most measures — his speech was unaffected, and he could walk, drive, and manage his own finances — but he was left with significant fatigue that built through the day and, on bad days, tremor and coordination trouble in his right hand. His neurologist described it as a real but variable disability: manageable on a good week, disruptive on a bad one, and not something that would fully resolve with time.
The stroke was not why David and Tom separated. Their marriage had been drifting apart for several years, and the health scare, if anything, delayed the conversation rather than caused it. But once they agreed to separate, the timing meant the parenting plan for Raymond had to be built around a version of David that did not exist when the two of them first became parents.
What the medical reality meant for parenting
David came to Treadstone Law with a clear starting position: he wanted equal parenting time with Raymond, split evenly week about, the way he assumed a fair separation was supposed to work. He had been an involved father throughout the marriage, and he did not want his health to be used as a reason to see less of his son.
The problem was not love or intent. It was stamina. A week-on, week-off schedule meant seven consecutive days of solo mornings, school drop-offs, homework, meals, and evening routines, with no built-in relief. David's fatigue tended to compound over several days rather than reset overnight, and his neurologist was candid in a letter prepared for the file: a schedule with no recovery days built in carried a real risk that David would struggle to sustain it, particularly during exam seasons or when Raymond had after-school activities stacked into the evening.
Under the Divorce Act and Ontario's Children's Law Reform Act, a parenting arrangement is supposed to reflect the best interests of the child, considering each parent's ability to meet the child's needs — not an even split for its own sake. A parent's health condition is a legitimate factor in that analysis, but only if it is put before the court, or the other parent, honestly and with proper medical evidence. Minimizing it to preserve a preferred schedule creates a different risk: a plan that looks fair on paper but breaks down in practice, forcing a return to court or mediation later, often after the child has already absorbed the disruption of a missed pickup or a parent too exhausted to help with a project due the next morning.
Tom, for his part, was not trying to use David's health against him. He was worried about Raymond having a consistent routine and, candidly, about being asked to cover for David on short notice once a schedule was locked in. Both concerns were reasonable, and both needed to be addressed in the plan itself rather than argued about after something went wrong.
What we did
- Started from the medical evidence, not the preferred outcome. Rather than negotiating from David's ideal schedule and defending it, our family lawyer asked David's neurologist to describe his functional limitations in practical terms — what a typical day and a bad day looked like, how far in advance fatigue could be predicted, and what kinds of parenting tasks were reliably manageable. That letter became the foundation of every schedule discussion that followed, rather than a footnote added to justify a position after the fact.
- Modelled several schedules against the real week, not the calendar. We worked through what a week-on, week-off arrangement would actually require of David during a school term with Raymond's activities factored in, then compared it to a shorter-rotation schedule with more frequent but smaller blocks of time, and to a plan with a fixed midweek recovery day built into David's parenting time. The goal was a schedule David could sustain in month six and month sixteen, not just the first week.
- Negotiated the parenting plan separately from the property division. With family property including a construction company, a former business sale, a matrimonial home, and a rental property, there was pressure to bundle everything into one global settlement. We kept the parenting discussion focused on Raymond's stability and David's health, resisting attempts to trade parenting time for a more favourable equalization payment. The two issues follow different legal tests, and blurring them tends to produce worse outcomes on both.
- Built in a review mechanism rather than treating the plan as final. The agreement included a scheduled check-in after eight months, with a defined, low-conflict process for adjusting the schedule if David's condition improved, worsened, or simply proved easier or harder to manage than expected in practice. This mattered because health conditions like David's often change gradually, and a plan with no way to adapt tends to force a choice between quietly breaching it or restarting a formal negotiation from scratch.
- Documented a support plan for David's parenting weeks. Rather than leaving David to manage alone on his lower-capacity days, the agreement named a family member available to help with school pickups and evening routines during David's parenting time, with Tom's agreement that this did not count against David's time with Raymond. Making this explicit in writing removed a recurring source of friction that otherwise surfaces informally, and awkwardly, months later.
The outcome
David did not get the equal, week-about schedule he originally wanted. The final parenting plan gave him a modified rotation weighted somewhat more toward Tom — roughly forty percent of overnight time to David, sixty percent to Tom — with David's parenting blocks shorter and more frequent, and a fixed midweek support day built into his schedule rather than left to chance.
That was a real loss, and David said so plainly during the negotiations. He had pictured something closer to equal, and letting go of that picture was harder than any of the financial terms in the separation agreement. But the alternative — insisting on equal time and hoping his stamina held — carried a much larger risk: a schedule that worked for the first month and then quietly failed, forcing either an uncomfortable renegotiation under strain or, worse, a missed week that left Raymond scrambling and gave Tom grounds to push for a much more restrictive arrangement down the line.
By building the plan around David's actual capacity from the start, supported by medical evidence rather than optimism, the family avoided that outcome. Eight months in, the scheduled review confirmed the arrangement was working: David's fatigue had been manageable within the modified rotation, Raymond had adjusted well to the routine, and no unplanned changes had been needed. The property division, negotiated separately, was completed on its own timeline based on business valuations for the construction company and the couple's other assets, without becoming entangled in the parenting dispute.
David has said since that accepting less time than he wanted, upfront and on paper, felt like a loss he had not been prepared for. What it bought him was a relationship with Raymond that has stayed steady rather than one that started strong and eroded under the weight of a schedule he could not actually sustain.
What you can learn from this
- A parenting schedule needs to survive a bad week, not just look fair on the day it is signed. If a parent's health, work, or other limits mean a schedule cannot be sustained consistently, that instability tends to hurt the child more than an honestly modified plan would.
- Medical evidence belongs in the plan from the start, not produced defensively after a problem arises. A clear letter describing functional limitations, not just a diagnosis, gives both parents and any mediator or court something concrete to work with.
- Keep parenting time and property division as separate negotiations where possible. Trading time with a child for a better financial outcome, or the reverse, tends to produce worse results on both fronts and can undermine the best-interests focus a parenting plan is supposed to have.
- Build a review date into the agreement itself. A health condition, a work schedule, or a child's needs can all change, and a plan with a defined, low-conflict path to adjust is far more durable than one that requires starting negotiations over from nothing.
- Naming practical support arrangements in writing, such as who helps on a lower-capacity day, prevents informal friction from building up and later being read as a failure to co-parent.
