The situation
Kasia and Luc had been married for twenty-seven years. She worked as a physiotherapist, he as a professional engineer, and between them their household income in Vaughan sat comfortably in the $150,000 to $300,000 range. Their son Rejean was another matter. He had struggled with substance use on and off for years, and when his relationship ended, his young daughter came to live with her grandparents. There was no court order, no agreement, not even a letter. Rejean dropped his daughter off with a bag of clothes and said he needed time to get stable.
Fourteen months later, she was still living with Kasia and Luc. She had her own room, was enrolled in the local school on the strength of Kasia signing forms as though she were the parent, and had settled into a routine. Rejean called every few weeks, sometimes from a treatment program, sometimes not. Nobody had formalized anything, because nobody wanted to be the one to suggest it. It felt, to Kasia and Luc, like formalizing it might mean admitting Rejean was not coming back for her — and they did not want to believe that yet.
What the gap actually cost
The trouble surfaced on a Tuesday morning, when their granddaughter woke up in pain from an abscessed molar that needed treatment under general anesthetic. The dental clinic asked the routine question: who has legal authority to consent to this procedure? Kasia was not the child's parent and held no guardianship order. Rejean was the child's legal parent, but he was unreachable — his phone was off, and the treatment facility he was staying at would not confirm whether he was even still enrolled. The clinic, reasonably, would not proceed without consent from someone who held the legal authority to give it. Treatment was delayed nine days while Kasia tracked Rejean down through a mutual family contact.
That was the moment that finally pushed them to call a lawyer, but it also crystallized something they had not previously thought about: for fourteen months, Rejean had remained his daughter's legal parent in every respect that mattered on paper, even though Kasia and Luc had been doing all of the actual parenting. The Canada Child Benefit, the federal monthly payment tied to who a child primarily lives with, was still being paid to Rejean's account, not theirs, because no one had ever told the government the child's residence had changed. Kasia and Luc had been covering daycare, clothing, medical and dental costs, tutoring and everyday expenses entirely out of their own pocket — roughly $46,000 over the fourteen months, by the rough tally we asked them to put together — while the money meant to help support her kept going to the one parent not raising her.
In Ontario, a non-parent — including a grandparent — can apply under the Children's Law Reform Act for decision-making responsibility (the authority to make significant decisions about a child's health, education and welfare) and parenting time (where the child lives and spends time). Courts do grant this to grandparents where it serves the child's best interests, but the longer that request waits, the more that gap in legal authority quietly costs the family living it — in consent forms nobody can sign, in benefits paid to the wrong household, and in support nobody has been actively pursuing.
What we did
- Filed for decision-making responsibility and parenting time on an urgent basis. We prepared the application under the Children's Law Reform Act naming Kasia and Luc jointly, supported by a clear account of the fourteen months of actual care, the school enrollment, and the dental delay as evidence of the practical harm caused by the current gap. Because Rejean did not oppose the application once served — he acknowledged he was not in a position to resume care — the matter proceeded largely on consent rather than as a contested hearing, which kept it faster and less expensive than a fight would have been.
- Put an interim consent-to-treat authorization in place immediately. Rather than waiting for the full court process to finish before their granddaughter could see a dentist or doctor again, we had Rejean sign a written authorization delegating medical and educational consent to Kasia and Luc while the application was pending. This is not a substitute for a court order, but it solved the immediate, recurring problem — another appointment, another form, another gatekeeper asking who has authority — while the paperwork caught up to the reality of who was raising the child.
- Redirected the Canada Child Benefit. Once the interim arrangement was documented, we helped Kasia and Luc update the federal benefit to reflect that the child was now living with them, so that going forward the monthly payment followed the household actually covering her costs rather than the household that no longer was.
- Pursued child support from Rejean, including a retroactive claim. Grandparents with decision-making responsibility can seek child support from a parent under the same framework a parent would use against another parent. We calculated what Rejean would have owed under the child support guidelines based on his income over the full fourteen months — roughly $900 a month, or about $12,600 in total — and included a retroactive claim covering that entire period in the application.
The outcome
The court granted Kasia and Luc decision-making responsibility and parenting time on consent, giving them the legal authority they should have had from the start — able to sign for medical care, enroll her in school under their own names, and travel with her without a note from Rejean each time. The Canada Child Benefit now reaches the household actually raising her. On the child support claim, the outcome was more mixed.
Retroactive child support is not automatic in Ontario. Courts weigh several factors before awarding support back to a date earlier than when the application was formally made — including how much notice the paying parent had that support was being sought, and how long the recipient waited before asking. Kasia and Luc had never raised the question of support with Rejean during those fourteen months; there had been no letter, no request, nothing putting him on notice that a claim might follow. The court awarded support running from the date the application was filed, but declined to make it fully retroactive to the start of the arrangement. In practical terms, they recovered support for roughly six of the fourteen months — about $5,400 of the $12,600 they had calculated — leaving a permanent shortfall of roughly $7,200 against what Rejean would otherwise have owed for that period.
That $7,200 is not a number Kasia and Luc are ever going to see. It is not a catastrophic sum against a household income in their range, and it did not put anything at risk the way it might have for a family with less financial cushion. But it was avoidable, and they knew it. The loss was not caused by anything they did wrong as caregivers — by every account they were doing right by their granddaughter every single day. It came entirely from the fourteen months where nobody wanted to be the one to say, out loud, that this needed to be made official.
What you can learn from this
- If a grandparent or other relative is raising a child full-time, formalizing it early matters — decision-making responsibility and parenting time under the Children's Law Reform Act give you the legal authority that everyday parenting already assumes you have.
- Informal care arrangements collide with the real world at the worst moments: a medical procedure, a school trip, a border crossing. By the time you discover the gap, you are usually dealing with it under pressure, not on your own timeline.
- Retroactive child support is discretionary, not automatic. Courts look at whether the other parent had notice a claim might be coming — waiting to raise it can permanently shrink what you can recover, even where the underlying entitlement was never in doubt.
- Benefits like the Canada Child Benefit follow whoever is on file as the child's primary residence, not whoever is actually paying the bills. If a child's living situation changes, that record needs to change with it.
- A written interim authorization — signed by the parent, covering medical and school consent — can solve the day-to-day access problem quickly while a full court application is still working its way through.
