The situation
'Can I still fix this, or did I already lose my chance?' That was the question Dragan asked in his first call with us, and it took most of the file to answer properly. Dragan worked as a home care aide, visiting clients across Tillsonburg and the surrounding towns on a rotating schedule that paid by the hour with no benefits attached. He and Samir had lived together for nine years, common-law the whole way through, in a small rented apartment. Samir cut hair at a salon that paid a modest base wage plus an annual bonus tied to the salon's yearly performance, a bonus that swung considerably from one year to the next depending on how the shop did.
When they separated, Dragan was entitled to support from Samir, since Samir's income was meaningfully higher once the bonus was factored in. A support worksheet went back and forth between them without lawyers involved at first, and Samir's side used the most recent year's income to calculate the number, a year in which the salon's bonus pool had been unusually small. The resulting support figure was low. Dragan sensed something was off but did not know how to challenge it, and by the time he came to see the number as a problem rather than just bad luck, the deadline to formally respond to the temporary support arrangement Samir's lawyer had proposed had already passed.
Dragan's household income sat under $45,000 even with support included, and he had few assets to fall back on while he sorted out what to do. He had also, in the meantime, learned that Samir had moved in with a new partner, Tarek, and Dragan worried, not entirely without reason, that this had quietly shaped how the numbers had been presented to him. He came to us not asking us to reopen a fight from scratch, but asking whether a missed deadline meant the low figure was now permanent.
It was a fair question, and not one with a simple yes or no answer. Deadlines in family law matter, but they do not always close every door at once, and figuring out which doors were still open, and which were not, was the first real piece of work on the file.
Dragan had never dealt with a lawyer before this, and the process of the temporary support proposal arriving, sitting in his inbox while he worked long shifts, and then quietly becoming the default figure once the response window passed, left him feeling like the system had moved without him rather than around him. He was not looking to punish Samir. He simply wanted the number to reflect what Samir actually earned, and he wanted to understand, in plain terms, whether that was still possible or whether he had already lost the chance by not knowing the rules in time.
What the law actually said
Support for a common-law partner in Ontario is generally governed by the Family Law Act rather than the Divorce Act, which applies to married spouses, but the underlying approach to income is similar in practice: support is meant to reflect a payor's real, ongoing earning capacity, not a single snapshot that happens to be low. Where a payor's income includes a variable component like a bonus, the Child Support Guidelines' approach to averaging income over multiple years is commonly used by analogy in spousal and partner support cases too, precisely because a single year can understate or overstate what someone actually earns over time.
The missed deadline complicated things but did not eliminate the underlying support claim. Because the earlier support arrangement had been agreed to on a temporary basis rather than fixed permanently by a court order after a full hearing, there remained a path to seek a variation going forward, based on a more accurate income figure. What that path could not do was reach backward as easily. Retroactive support, covering the months already paid under the low figure, is not decided by the missed deadline alone: a court weighs the reason for the delay, the payor's own conduct, above all any failure to disclose rising income, the effect on the household, and the hardship of reopening months already paid, and will typically look back around three years, further where the payor's conduct justifies it. Nothing in Samir's records suggested he had hidden a strong year or misstated what he earned; the low figure came from an ordinary calculation using the most recent year rather than from concealed income. That made Dragan's own delay in raising the issue carry real weight, and the case for reaching back further correspondingly weaker.
We also had to address Dragan's concern about Tarek directly, because it shaped how he understood the whole file emotionally even if it was not, in the end, the central legal issue. A new partner is not responsible for someone else's support obligation, and Tarek's earnings were not simply added to what Samir owed. But a new partner's income is not always beside the point: it can be looked at directly where undue hardship is claimed, and a new partner's contribution to shared household costs can bear on what a payor can realistically afford. Nothing here pointed toward an undue hardship argument, so what mattered was Samir's own income, properly calculated, and that meant going back through several years of salon bonus records rather than relying on the one low year that had set the original figure.
Explaining this to Dragan took real care. He had come in hoping a missed deadline was reversible in full. It was not. But the ongoing support obligation was not frozen at the low figure forever either, and untangling those two different questions, one closed and one open, was what let us build a workable strategy instead of either giving up or promising more than the file could deliver.
We also had to manage Dragan's expectations about what a court would realistically do if the matter ended up before a judge rather than settling by agreement. A judge asked to set support going forward would generally welcome a properly documented multi-year average over a single low year, since that is the more accurate and defensible approach. A judge asked to reopen months already paid under an informally accepted temporary figure, after the deadline to object had passed without response, would be far less receptive, particularly where the paying party could show reliance on the arrangement continuing unchallenged.
What we did
- Confirmed the status of the existing arrangement. We reviewed the correspondence between Dragan and Samir's lawyer and confirmed the support figure had been agreed to on a temporary, informal basis rather than locked in by a signed agreement or court order, which meant a variation going forward was legally available even though the response deadline for the original proposal had passed.
- Requested four years of Samir's income records. Rather than accepting the single low year the original figure relied on, we requested tax returns, T4 slips, and salon bonus statements going back four years, which is the kind of record needed to show a fair picture of genuinely variable income rather than one unrepresentative year. Four years gave us both strong bonus years and weak ones, which made the average difficult for Samir's side to dismiss as cherry-picked or unrepresentative of his real earning pattern.
- Calculated a four-year average bonus figure. Using the records obtained, we built an averaged annual income figure for Samir that smoothed out the swings between the salon's strong years and its weak ones, producing a number that better reflected what Samir could reasonably be expected to earn going forward rather than what one unusually quiet year at the salon happened to show. That averaged figure became the anchor for every negotiation that followed.
- Set aside the retroactive claim rather than overpromising on it. We advised Dragan candidly that the missed deadline weakened any claim to recover the difference for months already paid, and that pursuing it aggressively risked spending money and goodwill on a claim unlikely to succeed, so we focused the file on the stronger, forward-looking variation instead. That candour kept Dragan's expectations realistic and preserved the negotiating relationship with Samir's side for the parts of the file that still had real upside.
- Addressed the Tarek question directly and closed it. We explained plainly, in writing, why Tarek's income had no bearing on Samir's support obligation, which let Dragan set that concern aside and stop treating it as part of the negotiating strategy. Closing that question early meant later conversations with Samir's lawyer stayed focused on the actual income dispute rather than drifting into an irrelevant and potentially counterproductive argument about a third party's finances.
- Proposed a variation based on the averaged income. We sent Samir's lawyer a variation proposal using the four-year average rather than the most recent year, with the supporting records attached, framing it as a correction to an incomplete picture rather than a dispute over Samir's honesty. That framing mattered: it gave Samir's side a way to agree without conceding that anyone had acted in bad faith, which made a quick settlement far more likely than an accusatory opening position would have.
- Negotiated the effective date of the new figure. Since full retroactivity was unlikely, we negotiated instead for the corrected figure to take effect from the date we formally raised the issue, which recovered some ground without requiring a contested hearing on the missed deadline itself. That compromise date became the practical middle ground both sides could live with, and it avoided the cost and delay of litigating exactly when the correction should have started.
- Documented the whole file in writing for future reference. We put the final variation, the supporting income records, and the agreed effective date into a written agreement, so that if either Dragan's or Samir's circumstances changed again, there would be a clear, documented baseline to work from rather than another dispute over what had originally been agreed and why. That written record protects both of them the next time either side's income shifts and a further variation becomes necessary.
- Walked Dragan through deadline mechanics in plain terms. Because a missed deadline had started the problem, we spent additional time explaining generally how support proposals, response windows, and variation applications interact, so Dragan would recognize a similar deadline immediately if one arose again. That extra explanation was not billable strategy so much as an insurance policy against the same costly mistake happening a second time in a future dispute.
The outcome
Samir's side agreed to the averaged income figure without a hearing, which meaningfully increased Dragan's ongoing support going forward, reflecting Samir's real earning pattern rather than one weak bonus year. For a household already living under $45,000 in income, the increase mattered in practical terms every month, even though it was smaller in total than the amount Dragan would have received had the original figure been correct from the start.
The retroactive piece did not go Dragan's way. Samir's lawyer held firm that the earlier months had already been settled through the temporary arrangement Dragan had not responded to in time, and we advised Dragan that pushing further on that point carried real risk of legal costs without a strong likelihood of success. Dragan accepted that assessment, understanding it as the direct cost of the missed deadline rather than a failure in the later negotiation.
Dragan described the outcome afterward as a hard but useful lesson. He had come to us believing a missed deadline was either fully fixable or a total loss, and left with a more accurate understanding: some ground, once missed, does not come back, but that does not mean the whole file is lost if the underlying obligation is still open to correction. The four-year average became the figure both sides worked from going forward, which gave the ongoing arrangement a stability the original one-year snapshot never had.
For a household living under $45,000 a year, the difference between the low-year figure and the averaged figure was not abstract. It changed what Dragan could realistically budget for rent, transportation to his shifts, and the ordinary costs that had felt tight under the original number. The months lost to the missed deadline remained a genuine cost, one we did not try to minimize for Dragan, but the corrected ongoing figure meant that cost did not compound indefinitely into every future month as well.
What you can learn from this
- Respond to a proposed temporary support figure by the stated deadline whenever possible. A missed deadline can close off recovery of support already paid, even where the underlying figure turns out to be wrong once the full income picture is known.
- When a payor's income includes a bonus, commission, or other variable component, ask whether a multi-year average, not just the most recent year, gives a fairer and more defensible picture of what they actually earn over time.
- A new partner's income is not simply added to an existing support payor's obligation, though it can matter directly in an undue hardship claim or through their share of household costs. Where neither is in play, it is usually worth setting that concern aside early rather than letting it drive strategy.
- A missed deadline on one specific proposal does not necessarily freeze an ongoing support obligation permanently. Check whether the arrangement was ever formalized into a binding agreement or court order, since an informal temporary figure often remains open to variation going forward.
- Ask for several years of income records early, before agreeing to any support figure based on variable pay, rather than after a low figure has already become the default and a problem is only suspected in hindsight.
