Imputed Income and Child Support in Ontario: What You Need to Know

Child support in Ontario is based on income — specifically, the paying parent’s annual gross income. But what happens when a parent deliberately reduces their income, hides earnings, or is unemployed without good reason? Ontario courts have a powerful tool: imputed income.

What Is Imputed Income?

Imputed income is income that a court attributes to a parent, even if they are not actually earning that amount. It is used to prevent parents from manipulating their income to reduce their child support obligations.

Under the Federal Child Support Guidelines, a court may impute income where:

• A parent is intentionally under-employed or unemployed
• A parent has unreasonably deducted expenses that reduce their apparent income
• A parent receives income from a corporation they control and has not declared it as personal income
• A parent has failed to make full financial disclosure

When Will a Court Impute Income?

Courts do not impute income lightly. They look for evidence that a parent could earn more and is choosing not to — without reasonable justification.

Common scenarios where income is imputed:

1. Voluntarily Leaving Employment

If a parent quits a well-paying job without valid reason shortly before or after separation, a court may impute their former salary or a salary commensurate with their qualifications.

2. Refusing Suitable Employment

If a parent refuses job offers or fails to seek employment consistent with their education and experience, the court may impute what they could earn.

3. Self-Employment With Artificially Low Income

Self-employed parents and business owners have more flexibility in how they report income. Courts scrutinize business expenses closely. If personal expenses are being run through a business, or if dividends are being substituted for salary to reduce the apparent income, a court may impute the parent’s true income.

4. Working Below Qualifications

A lawyer or doctor who takes a minimum-wage job after separation may have income imputed at a level consistent with their professional qualifications and experience.

How Much Will the Court Impute?

Courts consider what the parent could reasonably earn given:

• Their education and training
• Their work history and experience
• Local job market conditions
• Any legitimate barriers to employment (health, caregiving responsibilities)

The court has significant discretion in determining the appropriate imputed amount.

Challenging an Imputed Income Motion

If your co-parent is seeking to have income imputed to you, you will need to provide evidence explaining your income situation:

• Documentation of job search efforts
• Medical evidence of any disability or health condition
• Evidence of caregiving responsibilities
• Tax returns and financial statements
• Employment records

Courts are not sympathetic to unexplained gaps in employment or dramatic income reductions without documentation.

If income is being imputed to you unfairly — for example, because of a legitimate career change, further education, or a genuine health issue — the evidence to support your position must be organized and compelling.

Practical Advice for Payors

If you are self-employed or run a corporation, maintain meticulous financial records. Be transparent in your financial disclosure. If you need to reduce your income for a legitimate reason, document the reason carefully. Courts respond to evidence — not explanations offered without support.

Practical Advice for Recipients

If you suspect the other parent is under-reporting income or has deliberately reduced their earnings, gather as much documentation as you can: prior tax returns, employment records, LinkedIn profiles, publicly available information about their business. A motion to impute income requires evidence.
