This week's Divorce Gotcha: Your ex can't just quit their job and watch the support number drop. Ontario courts have seen every version of this move — and imputed income is their counterpunch.

Here's a scenario that’s very common.

The separation happens. Your lawyer sits runs the numbers and trying to figure out what support payments are going to be. Then you mention that your ex recently quit their $120,000 sales job with benefits to "figure out what they want do with their life" – and that their income has (conveniently) plummeted.

Your lawyer pauses.

"Okay," they say, carefully. "Have you heard of imputed income?"

Here's what nobody explains upfront: in Ontario, the income number used to calculate spousal support isn't automatically the number on your ex's last paycheque. It's the number the court thinks they should be earning — based on their education, work history, qualifications, and the actual job market. If your ex quit, went part-time, or is running a hobby business that somehow shows no profit right around the time you separated, the court has a name for that: voluntary unemployment or deliberate underemployment.

The fix is imputed income. The court ignores what your ex claims to earn and assigns them an income based on their earning potential instead.

And this cuts both ways. If you're paying support and your ex is refusing to work when they're fully capable? Same tool applies. Their support gets calculated as if they had an income — not as if they spent two years doing nothing.

The gotcha is simple: people think they can engineer the support number by engineering the income number. Courts have seen every variation of this move. Imputed income is the counterpunch that closes that door.

The other thing people miss? It can be applied to you just as easily as to your ex. If you're on the receiving end of support and you're voluntarily not working, don't assume the court won't notice.

Here's exactly how it works.

What it is: The court assigns an income amount based on earning potential, not actual earnings

When it applies: Voluntary unemployment, deliberate underemployment, or hiding income

Who it applies to: Either spouse—payor OR recipient

The catch: Someone has to prove it, and courts need a "rational basis" for the number they pick

Let's cut through the legal jargon. "Imputed income" just means the court assigns you an income for support calculation purposes—regardless of what your tax return says.

The word "impute" literally means "to attribute." The court is attributing income to someone based on what they should reasonably be earning, given their skills, education, work history, and the job market.

This matters because spousal support (and child support) are calculated based on income. If someone can manipulate their income—by quitting their job, going part-time, or hiding money through a business—they can manipulate the support amount.

Courts aren't naive. They've seen every trick. And imputed income is their tool to keep things fair.

Section 19 of the Federal Child Support Guidelines (which Ontario courts also apply to spousal support) lists the situations where income can be imputed. But here's what that looks like in real life:

Your ex had a perfectly good job making $90,000 a year. Then, right around separation, they quit. Now they're "between opportunities" and claiming they should only pay support based on zero income.

The court will likely impute their previous salary—or something close to it. Quitting your job to avoid support obligations is exactly what this rule was designed to catch.

David was a sales manager making $120,000. Two months before separation, he quit to "pursue his passion" for woodworking. His new business shows a loss on paper.

What happens: The court imputes his previous income of $120,000 for support calculations. His "passion project" doesn't change his obligations.

This one's trickier. Your ex is working—but not at their full capacity. Maybe they have a law degree but they're working at a coffee shop. Maybe they're a skilled tradesperson working 20 hours a week when they could easily work 40.

If the underemployment is deliberate, the court can impute income based on their full earning potential.

This is the frustration I hear most often: "Why should I pay more just because my ex refuses to get a job?"

Here's the deal: if you're receiving spousal support, you have an obligation to make reasonable efforts to become self-sufficient. That's not just a moral expectation—it's embedded in the law.

If you're capable of working, have no young children at home, and just... don't feel like it, the court can impute income to you. That means your spousal support gets calculated as if you were earning something, which reduces what you receive.

Lisa was a stay-at-home mom during the marriage. The kids are now 15 and 17. She has a college diploma and previous work experience. She's made no effort to find work in the two years since separation.

What happens: The court imputes income to Lisa based on what she could reasonably earn—maybe $45,000 in an administrative role. Her spousal support is calculated using that number, not zero.

This is where things get complicated. If your ex owns a business or has a private corporation, there are ways to make income "disappear" on paper:

Courts see through this. They'll look at the corporation's total income, retained earnings, and whether the business is paying for things that should be personal expenses. Then they'll impute an income that reflects the actual economic benefit your ex is receiving.

Some businesses deal primarily in cash. Restaurants, contractors, some retail businesses. If the reported income seems suspiciously low given the lifestyle, courts can impute a higher income.

The classic red flag: they're reporting $40,000 a year but somehow own two cars, a boat, and take vacations to Mexico every winter. Courts aren't stupid.

Here's where it gets legally important. If you want income imputed to your ex, you have to prove it.

Specifically, you need to prove that their unemployment or underemployment is voluntary—that it's a choice, not a circumstance beyond their control.

Once you prove that, the burden shifts. Your ex then has to prove either:

The good news: once you've established that income should be imputed, you don't have to prove the exact amount. The court will figure that out based on evidence of earning potential.

If you're trying to get income imputed to your ex (or defending against it being imputed to you), here's what matters:

What did they do before? What did they earn? A sudden drop in income right around separation raises eyebrows.

A lawyer who's suddenly "only able" to work retail has explaining to do. Your qualifications establish your earning potential.

Legitimate health issues can explain unemployment. Age matters too—courts are more understanding of a 60-year-old having trouble finding work than a 35-year-old.

Are they actually looking for work? Applications, interviews, rejection letters, networking—all evidence of genuine effort. No evidence of job searching? That suggests the unemployment is voluntary.

What jobs are available in their field? What do they pay? Courts look at real market conditions, not hypothetical dream jobs.

If they're living large on supposedly minimal income, something doesn't add up.

Courts can't just pick a number out of thin air. The Ontario Court of Appeal has been clear: there must be a "rational basis" for whatever income is imputed.

In practice, courts typically look at:

Marcus was a project manager earning $85,000. He quit and now works part-time at his brother's company for $25,000.

The court looks at job postings for project managers in his area. Average salary: $78,000-92,000. His previous salary of $85,000 fits that range.

Result: Income imputed at $85,000—there's a rational basis (his actual previous salary in line with market rates).

Income imputation isn't automatic just because someone's not working. There are legitimate reasons for unemployment or underemployment:

If a parent is the primary caregiver for young children, courts often won't impute income—or will impute a reduced amount that accounts for part-time work only. The age of the children matters: caring for a 2-year-old is different from caring for a 14-year-old.

Genuine health problems that prevent work are valid reasons for unemployment. But you need medical evidence. Vague claims of "stress" without documentation won't cut it.

If someone is getting education that will improve their earning potential, courts may not impute income during that period—within reason. A 2-year nursing program? Probably reasonable. A 6-year philosophy PhD at age 50? Harder sell.

Getting laid off isn't voluntary. But the clock is ticking. Courts expect you to actively look for new work. Six months of unemployment with active job searching? Understandable. Two years with no effort? Income gets imputed.

If someone genuinely can't find work in their field despite trying, courts consider that. This was more common during COVID—courts recognized that some industries simply shut down.

Don't forget: this isn't just a tool for payors to use against recipients. It works in reverse too.

If you're the lower-earning spouse and your ex suddenly "can't afford" support because they quit their $200,000 job to become a yoga instructor, you can ask the court to impute their previous income.

The same rules apply: you need to prove the income reduction was voluntary and unreasonable.
