Averaging three volatile years to set fair support in Caledon

The situation

'Which year am I supposed to use?' Bailey asked in the first meeting, sliding three tax returns across the table, one after another. One showed close to one hundred and sixty thousand dollars, from a year when everything seemed to close at once. One showed just under eighty thousand. The third, from the year the local market had slowed sharply, showed barely sixty. All three were real, filed and accurate. None of them, taken on its own, told her what support for her son should actually be going forward.

Bailey worked as a real estate agent, paid entirely on commission with no base salary to fall back on, and had been the primary parent to her son since separating from Nuwan, an elementary school teacher whose income, by contrast, moved only slightly year to year on a fixed schedule. The mismatch created an ongoing argument that neither side could resolve informally: Nuwan's side wanted to use Bailey's lowest year, on the reasoning that it was the most recent and therefore the most relevant, while Bailey worried, with some justification, that using any single year, high or low, would misrepresent what she actually had available to support her son over the medium term.

The three years reflected real swings in the housing market, not anything within Bailey's control or connected to how hard she worked. A strong year with several large closings back to back sat next to a slow year when interest rate changes froze buyers for months at a stretch, cutting her closings by more than half. Her son's needs, meanwhile, did not fluctuate with the market the way her income did; school costs, extracurricular activities, and ordinary day-to-day expenses stayed roughly constant regardless of which year Bailey's commissions happened to land in.

Halfway through the process of gathering the financial picture, Bailey's mother Chelsea, who had been helping with after-school childcare several days a week and was a steady presence in her grandson's routine, was diagnosed with a serious illness. What had been a straightforward, if numerically messy, support file suddenly had to move around hospital appointments, a temporarily shifted custody schedule while Bailey managed caregiving on top of her usual work, and stretches of weeks where financial paperwork was simply, understandably, not the household's priority.

Why this was harder than it looked

Ontario's child support guidelines are built around a parent's current, ongoing income, which is a straightforward calculation when a parent draws a stable, predictable salary. Commission-based income breaks that assumption almost entirely. The guidelines account for this by allowing income to be calculated using an average of recent years, rather than the most recent return alone, where a parent's income pattern is genuinely variable rather than simply trending up or down. The difficulty in practice is not whether averaging is permitted at all; it is deciding how many years to include, which years count as representative, and how to weight a year that was unusually strong or unusually weak against the others.

Nuwan's position, that the most recent and lowest year should govern the calculation, is a common argument in files like this one and is not unreasonable on its face: recent income is often, in principle, the best predictor of near-term ability to pay. But a single low year in a commission-based career can reflect a temporary, market-wide slowdown rather than any lasting drop in a parent's actual earning capacity, and setting support permanently on that basis risks locking in a number Bailey's real income would soon outpace again once the market recovered, leaving her son underfunded relative to what she genuinely had available.

The counter-risk was equally real and needed to be acknowledged honestly. Using Bailey's strongest year instead would have set support at a level her income did not reliably support in the following year, creating financial pressure that a genuinely slower market could quickly turn into arrears she could not realistically pay down. Neither a single high year nor a single low year served her son's actual, ongoing needs as well as a proper average that smoothed the swings without pretending they did not exist.

The illness in Chelsea's household added a second layer of difficulty that had nothing to do with income calculation and everything to do with timing. Custody arrangements built around Chelsea's regular after-school help needed to flex while Bailey balanced caregiving responsibilities alongside her own work, and the financial disclosure process, which depends on a parent having uninterrupted time to locate records, gather statements, and respond to requests, slowed accordingly through no fault of either party. Getting the numbers right and getting the timeline right turned out, in the end, to be two separate problems that both needed deliberate handling.

What we did

1. Assembled Bailey's full commission history across three complete tax years plus year-to-date figures for the current one, requesting brokerage statements and year-to-date deposit records alongside the returns themselves. This gave a complete, verifiable picture rather than the narrower three-return snapshot Nuwan's side had initially focused its argument on, and it became the foundation every later averaging argument in the file had to rest on.
2. Proposed a three-year averaging model, weighting each year equally rather than favouring the most recent one, on the basis that Bailey's income pattern showed genuine, market-driven variation over time rather than a clear upward or downward trend that would justify weighting a particular year more heavily than the others, an approach that treated three genuinely different years as equally representative of Bailey's real earning pattern going forward.
3. Worked with an accountant to verify the averaged figure against Bailey's actual bank deposits, brokerage statements, and brokerage-issued commission summaries, closing off any argument that the reported totals on her tax returns understated or overstated what she had genuinely received in a given year, which gave the average real credibility once it was put in front of Nuwan's counsel and, eventually, the court.
4. Documented the market conditions behind the slow year specifically, gathering publicly available interest rate and regional listing data for the relevant period to show the downturn was broad and temporary, affecting agents across the area, not something particular to Bailey's own business, effort, or client base that a court might otherwise mistake for a lasting decline in her effort, client base, or earning capacity as an agent.
5. Adjusted the parenting and disclosure timeline once Chelsea's diagnosis arose, requesting reasonable, documented extensions on document deadlines and proposing a temporary shift in the custody schedule that accounted for Bailey's caregiving responsibilities without abandoning or pausing the underlying support process entirely while the family managed the immediate crisis, so neither the parenting arrangement nor the support file collapsed under the same pressure at once.
6. Responded to Nuwan's low-year proposal directly once the market data was assembled, showing that the slow year coincided precisely with the documented downturn rather than any change in Bailey's business or client base, which meaningfully undercut the argument that a single weak year, chosen because it happened to be the most recent, represented her genuine, ongoing earning capacity going forward.
7. Negotiated a built-in review point for one year after the initial order, so the averaged figure could be revisited once a fourth year of data existed, rather than treating the three-year average as a permanent fixture regardless of how Bailey's income moved afterward in either direction as the market shifted again in either direction, rather than locking in a number that might quickly become outdated.
8. Finalized a support order on the averaged figure, once Nuwan's side reviewed and accepted the accountant-verified numbers and the market documentation, closing the file without a contested hearing despite the real disagreement over methodology that had shaped much of the earlier negotiation between the two sides and could easily have ended up before a judge instead.
9. Coordinated the effective date of the new order with the parenting schedule change made necessary by Chelsea's illness, so the two adjustments, income and custody, took effect together rather than creating two separate points of friction for Bailey and Nuwan to manage in the same difficult season for their family, which made the transition easier for Bailey to manage alongside her mother's care.
10. Kept Nuwan's counsel informed of the reason for each delay as it arose, rather than letting extension requests go unexplained, which preserved goodwill through the caregiving disruption and made it easier to return to the averaging discussion once the household's situation had stabilized enough for Bailey to focus on it again, rather than treating every delay as a dispute in itself.

The outcome

The three-year average landed at roughly one hundred thousand dollars, above the lowest year Nuwan had originally proposed and below the strongest year Bailey had once had. Support was set on that figure, giving Bailey's son a number grounded in a real, sustained pattern of earnings rather than whichever single year happened to suit one side's negotiating position at the time. The gap between Nuwan's proposed figure and the final averaged number was substantial enough that had the low year prevailed, Bailey's son would have received meaningfully less support for years to come, even as her income recovered.

The caregiving disruption from Chelsea's illness added a few months to a process that would otherwise have moved considerably faster, and the temporary custody adjustment meant Bailey's parenting time shifted for a stretch while she managed hospital visits and her mother's recovery on top of her usual work. Neither side treated the delay as a reason to walk away from the averaging approach once the process resumed; the extensions granted during that period held without dispute, and the file did not need to restart from scratch once Chelsea's condition stabilized enough for the household's routine to settle again.

With the review point built into the order, Bailey now has a clear mechanism to revisit the figure as another year of commission data comes in, rather than facing an open-ended dispute every time a slow quarter or a particularly strong one shows up on her return. Her son's support reflects what her income has actually looked like over time, verified against real records, not a single year chosen because it happened to be convenient for the other side's argument at the moment the file was opened. Chelsea, for her part, recovered well enough over the following months to resume some of her earlier childcare role, and the parenting schedule returned close to what it had been before her diagnosis.
