Frequently Asked Questions

Common questions about spousal support in Ontario.

How is spousal support calculated in Ontario?
Spousal support in Ontario is typically calculated using the Spousal Support Advisory Guidelines (SSAG). The SSAG provide formulas that generate a range of support amounts (low, mid, and high) based on the incomes of both parties, the length of the relationship, and whether there are dependent children. Divorcepath applies these formulas with Ontario-specific tax calculations to show the net financial impact of different support amounts.
Are the SSAG mandatory in Ontario?
The SSAG are advisory, not mandatory. However, Ontario courts routinely use the SSAG ranges as a starting point for determining spousal support. Judges may order support outside the SSAG ranges based on the specific circumstances of the case, but departures from the ranges typically require explanation. Having an accurate SSAG calculation is essential for any spousal support negotiation or court application in Ontario.
How long does spousal support last in Ontario?
The duration of spousal support depends on the length of the relationship and the ages of the parties. Under the SSAG, the general rule is 0.5 to 1 year of support for each year of the relationship. For longer relationships (20+ years) or where the recipient is near retirement age, support may be indefinite. Divorcepath calculates both the amount and duration ranges under the SSAG for Ontario families.
Can common-law partners get spousal support in Ontario?
Ontario courts apply the SSAG as a starting point for spousal support. Under the Family Law Act, common-law partners who have cohabited for at least three years, or who have a child together and are in a relationship of some permanence, can claim spousal support. Divorcepath calculates spousal support for both married and common-law partners in Ontario.
What is the difference between the with-child and without-child formula?
The SSAG has two formulas. The without-child formula applies when there are no dependent children and is based on the income difference between the parties and the length of the relationship. The with-child formula applies when there are dependent children and accounts for child support obligations, government benefits, and tax implications. Divorcepath automatically applies the correct formula based on your situation.
Is the calculator accurate for Ontario?
Yes. Divorcepath uses the current SSAG formulas and applies Ontario's specific provincial tax rates, credits, and benefit calculations. The calculator is trusted by over 500 Canadian law firms and has been used by more than 300,000 Canadians. Reports generated by Divorcepath are accepted in Ontario courts for negotiation, mediation, and litigation.
Do I need a lawyer to calculate spousal support?
You do not need a lawyer to calculate spousal support. Divorcepath provides the same professional-grade SSAG calculations used by family lawyers across Canada. However, spousal support can be complex, especially when there are issues like imputed income, retroactive support, or disability. For complex situations, consulting a Ontario family lawyer is recommended.
