Child Support in Alberta

How Child Support Works in Alberta

Child support in Alberta is governed by the Federal Child Support Guidelines and the Divorce Act (Canada) (for married parents) or the Family Law Act (Alberta) (for unmarried parents). Support is based on:

  • The payor’s income
  • The number of children
  • Parenting arrangements
  • Special or extraordinary expenses (Section 7)

Child support is the right of the child (not the parents) and cannot be waived.

Base (Table) Child Support

Base child support is determined using the Federal Child Support Tables. It covers:

  • Food
  • Clothing
  • Basic shelter
  • Transportation
  • Everyday expenses

The amount depends on:

  • The payor’s Guideline Income
  • The number of children
  • The province of residence

In shared parenting arrangements (40%+ time with each parent), a set‑off calculation is generally used.

Each requires a tailored approach to valuation, division, and tax planning.

Section 7 Expenses (Special or Extraordinary Costs)

Section 7 expenses are additional costs that go beyond day‑to‑day needs. These may include:

 

  • Childcare
  • Medical and dental expenses
  • Health insurance premiums
  • Extracurricular activities
  • Post‑secondary education
  • Tutoring or special educational needs

 

These expenses are typically shared proportionate to each parent’s income.

Determining Income for Child Support

Accurate income determination is essential. For employees, this is straightforward. For business owners, professionals, or individuals with variable income, it can be more complex.

 

Income may include:

 

  • Salary
  • Dividends
  • Bonuses
  • Commissions
  • Retained earnings
  • Corporate benefits
  • Shareholder loans
  • Investment income
  • Rental income

 

The Guidelines allow the court to impute income if a parent is under‑employed, hiding income, or using corporate structures to reduce reported earnings.

Your corporate and tax background gives you a significant advantage in these cases.

Child Support for Business Owners and Professionals

When a parent owns a business or professional corporation, determining income may require:

 

  • Reviewing corporate financial statements
  • Normalizing income
  • Identifying personal expenses paid through the corporation
  • Assessing retained earnings
  • Evaluating shareholder loans
  • Reviewing dividends and salary choices

 

A detailed analysis ensures child support reflects true financial capacity.

Shared, Split, and Primary Parenting Arrangements

Parenting arrangements may affect how support is calculated:

 

Primary Parenting

One parent has the child more than 60% of the time.
→ The other parent pays full table support.

 

Shared Parenting (40%+ each)

Support is usually calculated using the set‑off method.
→ Each parent’s table amount is calculated, and the difference is paid.

 

Split Parenting

Each parent has at least one child primarily in their care.→ Each pays table support for the child(ren) in the other’s care.

Retroactive Child Support

Retroactive support may be ordered when:

 

  • A parent failed to disclose income increases
  • Support was based on outdated income
  • A parent avoided or delayed payment
  • A child’s needs were not met

 

Courts can order support going back several years, depending on the circumstances.

Changing (Varying) Child Support

Child support can be varied when there is a material change in circumstances, such as:

 

  • Income changes
  • Parenting schedule changes
  • New Section 7 expenses
  • Employment changes
  • Health issues

 

Variations can be made through negotiation, mediation, arbitration, or court.

Enforcement Through the Maintenance Enforcement Program (MEP)

MEP can enforce child support orders and agreements by:

 

  • Garnishing wages
  • Seizing bank accounts
  • Suspending driver’s licences
  • Intercepting tax refunds
  • Registering liens
  • Initiating court enforcement

 

MEP is a powerful tool when a parent is not paying support.

Child Support in Alberta FAQs

How is child support calculated in Alberta?

Child support is calculated using the Federal Child Support Guidelines, which consider the payor’s Guideline Income, the number of children, and the parenting schedule. The calculation is standardized, but income determination can be complex for business owners or individuals with variable earnings.

Base (table) child support covers day‑to‑day needs such as food, clothing, and basic shelter.


Section 7 expenses are additional costs like childcare, medical expenses, extracurricular activities, and post‑secondary education. These are usually shared proportionate to each parent’s income.

Guideline Income is based on Line 15000 of your tax return, adjusted for factors such as:

  • Dividends and shareholder loans
  • Corporate benefits
  • Bonuses and commissions
  • Retained earnings
  • Rental or investment income
  • Non‑recurring income
    For business owners, a detailed financial review may be required to determine true income.

If each parent has the child 40% or more of the time, support is calculated using the set‑off method. Each parent’s table amount is determined, and the difference is paid by the higher‑income parent.

Courts can impute income when a parent is intentionally under‑employed, failing to disclose income, or using corporate structures to reduce reported earnings. This ensures support reflects actual financial capacity.

Section 7 expenses are shared based on each parent’s proportionate income. For example, if one parent earns 70% of the combined income, they typically pay 70% of Section 7 costs.

Yes. Child support can be varied when there is a material change in circumstances, such as income changes, new Section 7 expenses, or changes in the parenting schedule. Annual income updates are recommended.

Retroactive support may be ordered when a parent:

  • Failed to disclose income increases
  • Paid less than required
  • Delayed updating support
  • Avoided financial disclosure

Courts can order support going back several years depending on the circumstance.

The Maintenance Enforcement Program (MEP) can enforce payment by:

  • Garnishing wages
  • Seizing bank accounts
  • Suspending licences
  • Registering liens
  • Intercepting tax refunds

MEP is a powerful enforcement tool when support is unpaid.

Yes. Child support for unmarried parents is governed by Alberta’s Family Law Act, but the calculation method is the same as for married parents under the Federal Guidelines.

Support typically continues until a child is:

  • 18 and independent, or
  • Over 18 but still dependent due to school, disability, or other factors

Post‑secondary support is common and often includes tuition, books, and living expenses.

Parents can negotiate support, but agreements must be consistent with the child’s best interests. Courts may set aside agreements that significantly deviate from the Guidelines without justification.

Common documents include:

  • Tax returns and Notices of Assessment
  • Pay stubs
  • Corporate financial statements
  • Investment and rental income records
  • Childcare and medical receipts
  • Post‑secondary documentation

Complete disclosure ensures accurate and enforceable support.

Not necessarily. Child support can be resolved through negotiation, mediation, arbitration, or court. Legal guidance ensures calculations are accurate, agreements are enforceable, and your child’s needs are fully addressed.

The first step is a consultation to review income, parenting arrangements, Section 7 expenses, and your goals. From there, a clear strategy is developed to ensure your child’s financial needs are met and your rights are protected.
