Child and Spousal Support Lawyers
When a relationship ends, financial obligations between former partners and toward children do not end with it. Child support and spousal support are legal responsibilities that arise from separation and divorce and getting them right matters for everyone involved. In Ontario, child support is calculated under the Child Support Guidelines, and spousal support is governed by the Family Law Act and the Divorce Act.
Questions about how much support is owed, for how long, and what happens when circumstances change are common, and the answers are rarely straightforward. Our family law team can take you through the process of assessing spousal and child support obligations, support entitlement, and enforcement of payments.

Our Approach to Spousal & Child Support Disputes
Every matter begins with a thorough consultation. We take time to understand your full financial picture, the history of the relationship, and your immediate concerns before recommending a path forward. For child support matters, we review income documentation and identify whether the standard Guideline table amount applies or whether additional analysis is needed. For spousal support, we assess entitlement on both compensatory and needs-based grounds. From there, we develop a strategy tailored to your goals and pursue a negotiated resolution wherever possible.
When negotiation is not possible, we are prepared to represent you in court. Once a support order or agreement is in place, we ensure you understand your obligations and rights going forward, and we remain available when circumstances change and a variation or enforcement issue arises.

Frequently Asked Questions
How is child support calculated in Ontario?
Child support in Ontario is calculated under the Child Support Guidelines. The Guidelines set a table amount based on the paying parent’s gross annual income and the number of children entitled to child support. In most cases, the table amount is the amount that will be paid. However, the calculation becomes more complex in certain situations, including: where children divide their time approximately equally between both parents, where the paying parent’s income exceeds $150,000 per year, where the paying parent is voluntarily unemployed or underemployed, or where paying the table amount would cause undue hardship. In addition to the table amount, parents may also be required to share special and extraordinary expenses under section 7 of the Guidelines, such as childcare costs, medical and dental expenses, and post-secondary education costs.
Who is entitled to spousal support in Ontario?
Entitlement to spousal support is not automatic. Under the Family Law Act and the Divorce Act, spousal support may be available where one partner experienced economic disadvantage as a result of the relationship or its breakdown, where one partner made sacrifices in their career or earning capacity to support the other’s career or to care for children, or where there is a significant financial disparity between the parties at the time of separation.
Common law partners who have cohabited for at least three years, or who have a child together, may also be entitled to spousal support. Entitlement, amount, and duration are each assessed separately, and the Spousal Support Advisory Guidelines are used to calculate a range for amount and duration based on the specific facts of the relationship.
Can child support be changed?
Yes. Whether determined by an order or an agreement, Child support is intended to reflect the current circumstances of both parents, and it can be varied when there is a material change in circumstances. The most common reason for varying child support is a change in the paying parent’s income. Because child support is based on gross income, it should be adjusted when income rises or falls. If a payor’s income drops due to a legitimate reason beyond their control, such as job loss or a health issue, the obligation may be reduced. If a payor voluntarily takes a lower-paying position or leaves the workforce without justification, it may be necessary to impute income and maintain the existing obligation. Either parent can return to court to seek a variation, and support orders can also be varied by agreement without a court proceeding.
Does child support end when a child turns 18?
Not necessarily. Child support continues as long as a child remains a dependent child within the meaning of the applicable legislation. A child who is enrolled in full-time post-secondary education is often still considered a dependent and may be entitled to continued support, though the calculation is different from the standard table amount. Factors including the child’s ability to contribute to their own expenses, the number of months the child lives at home during the year, and the expenses associated with their education are all considered.
Can a spousal support order be changed after it is made?
While some spousal support orders are non-variable, most can be changed if there is a material change in circumstances. This could be material changes in the spouses’ incomes, living arrangements, employment, child support payable or received or a variety of other factors that impact a support payor or support recipient’s financial circumstances. Either spouse can return to Court to seek a variation, and support orders can also be varied by agreement without a Court proceeding.
