Separation vs. divorce: the key difference
These terms are often used interchangeably, but they mean different things in Ontario law:
Separation
No court order or legal document required. Occurs when spouses decide to live "separate and apart" with the intention to end the marriage. You can be separated while living in the same house — courts look at the totality of the relationship.
Valuation date for family property = date of separation
Divorce
A court order under the Divorce Act that legally ends the marriage. Requires one year of separation (in most cases) before it can be granted. Once divorced, either party can remarry. Property and support issues can be resolved separately from the divorce itself.
Can be uncontested (joint application) or contested (one spouse applies)
Practical note: Many couples resolve all issues (property, support, parenting) in a Separation Agreement while still legally married. The divorce itself can follow years later. There is no legal requirement to divorce immediately after separation.
Property division: equalization of net family property
Ontario's Family Law Act creates a regime of "equalization of net family property." This is not a 50/50 split of all assets — it is an equalization of what each spouse accumulated during the marriage.
The formula: each spouse calculates their Net Family Property (NFP) = (assets at separation date) minus (debts at separation date) minus (assets owned at date of marriage).
The spouse with the higher NFP pays half the difference to the lower NFP spouse. This is the equalization payment.
Matrimonial home
Special rules: the matrimonial home (the home you lived in as a family) is excluded from the deduction of property at marriage — its full value is included in NFP regardless of when you owned it. Both spouses have equal right to possession regardless of whose name is on title.
Inheritance and gifts
Property received as an inheritance or gift during the marriage is excluded from NFP — but only if it was kept separate and traceable. If the inheritance was mixed into joint funds, the exclusion may be lost.
Pre-marital assets
Assets owned at the date of marriage are deducted from NFP (with exceptions). This requires documented proof of value at the marriage date — often complicated years later.
Common-law partners
Common-law partners in Ontario do not have NFP equalization rights. Their property claims are based on unjust enrichment and constructive trust — a different and more unpredictable legal process.
Spousal support
Spousal support in Ontario is governed by the Divorce Act (for married couples) and the Family Law Act (for all spouses including common-law). Support may be awarded where one spouse suffered an economic disadvantage from the marriage or its breakdown.
The Spousal Support Advisory Guidelines (SSAG) provide range formulas for amount and duration — but these are advisory, not binding. Courts retain discretion. Key factors:
Length of the marriage or cohabitation
Roles during the marriage (career sacrificed, primary caregiver)
Income and earning capacity of each spouse
Economic disadvantage or advantage from the marriage or breakdown
Standard of living during the relationship
Age and health of the spouses
Child support in Ontario
Child support is determined by the Federal Child Support Guidelines. Unlike spousal support, child support is largely formulaic:
Table amount
Set by the federal guidelines based on payor's province of residence, income, and number of children. A table amount lookup is public and easy to calculate.
Section 7 expenses
Special or extraordinary expenses shared proportionally — childcare, medical/dental not covered by insurance, extracurriculars, post-secondary.
Shared parenting adjustment
Where each parent has the child 40%+ of the time, set-off provisions apply. Support is reduced based on the differential in income and time.
Adult children
Support may continue past age 18 if the child is a full-time student, has a disability, or remains under parental charge for another reason.
Parenting arrangements (formerly custody and access)
The 2021 amendments to the Divorce Act replaced "custody" and "access" with "decision-making responsibility" and "parenting time." The framework focuses on the child's best interests, not parental rights:
Decision-making responsibility
Who makes major decisions about the child's health, education, religion, and significant extracurricular activities. Can be shared (joint) or given to one parent.
Parenting time
The schedule of when the child is with each parent. Arrangements range from primary residence with one parent to equal sharing to anything in between.
Best interests of the child
The governing standard for all parenting decisions — courts consider safety, each parent's relationship with the child, the child's views, ability to cooperate, and any history of family violence.
