Separation and divorce are among the most financially disruptive events in a person's life. In Canada, family law is primarily provincial, meaning the rules on property division and spousal support depend on where you live. This guide provides a practical overview of the financial steps involved.
In Canada, you are legally separated when you and your spouse decide to live apart with the intention to end the marriage. There is no legal process required to be separated — you simply begin living separately. Divorce is the legal dissolution of the marriage, granted by a court. You must be separated for at least one year before a divorce is granted (except in cases of adultery or physical/mental cruelty).
Most financial issues — property division, support, and custody — are dealt with during the separation period, often without waiting for a formal divorce order.
Property division on separation is governed by provincial law, not the federal Divorce Act. The Divorce Act covers divorce, child support, spousal support, and custody — but property is purely provincial.
The general principle is equalization or equal division of property accumulated during the marriage. Each province has specific rules:
Quebec's default matrimonial regime — partnership of acquests — divides assets accumulated during the marriage. The family patrimony provisions apply to all Quebec couples regardless of regime and require equal division of certain assets (family home, household contents, vehicles, and RRSPs/RRIFs accrued during marriage).
In many provinces, the matrimonial home gets special treatment. In Ontario, for example, the home is included in the equalization calculation even if owned by one spouse before marriage. In BC, the family home is family property regardless of whose name it is in.
Practically, the home is often the largest shared asset. Options include: one spouse buys out the other, the home is sold and proceeds split, or an agreement to maintain joint ownership temporarily (e.g., until children finish school).
Registered accounts are generally included in family property calculations. Under provincial family law, you can transfer funds between RRSP accounts of separating spouses without tax consequences using a direct transfer. See our dedicated page on Splitting RRSPs and Pensions in Divorce.
Spousal support (also called alimony or maintenance) may be payable by the higher-income spouse. The Spousal Support Advisory Guidelines (SSAG) provide a range of amounts and durations based on the length of the marriage and income difference, but they are advisory, not mandatory. Factors include: length of cohabitation, income disparity, economic disadvantage suffered, and care of children.
Spousal support is taxable to the recipient and tax-deductible to the payer (if paid under a written agreement or court order for periodic payments).
Child support is calculated using the Federal Child Support Guidelines (or provincial equivalents), based primarily on the payor's income and the number of children. It is not optional — courts will order it regardless of whether parents agree. Child support is not taxable to the recipient parent and not deductible by the payor.
An uncontested divorce (agreement already in place) costs approximately $1,500–$3,000 in legal fees plus the $636 federal filing fee (as of 2025). A contested divorce can cost tens of thousands of dollars or more. Mediation typically runs $3,000–$100 for a full resolution — far less than litigation.
