Dividing Property on Divorce in Canada: By Province

The federal Divorce Act grants the divorce itself but says nothing about who gets what; dividing property after a Canadian divorce is governed entirely by provincial law, and the three main provinces use genuinely different models.

The Divorce Act Does Not Divide Property

This is the single most misunderstood point in Canadian family law. The Divorce Act is a federal statute. It sets the ground for divorce (breakdown of the marriage), the residency rule for filing, and it governs corollary relief for married spouses: spousal support and parenting arrangements (decision-making responsibility, parenting time, and contact orders, the terms Bill C-78 introduced when it came into force March 1, 2021, replacing "custody" and "access").

What the Divorce Act does not do is divide the house, the pension, the investments, or the debts. Property is constitutionally a matter of provincial jurisdiction in Canada, so each province and territory has its own statute governing how spouses divide what they own when a marriage ends. A couple can be validly divorced under federal law while their property dispute is still working its way through a completely separate provincial court process, under a completely separate statute, on its own timeline.

That split matters practically. Getting a divorce and dividing property are two different applications, sometimes heard together and sometimes not, and the deadlines that apply to each run independently. See divorce in Canada for how the federal divorce ground and residency rule work on their own.

Ontario (and Most Common-Law Provinces): Equalization of Net Family Property

Ontario's Family Law Act does not split individual assets between spouses. Instead, it uses equalization. Each spouse calculates their net family property: the value of everything they own on the valuation date (generally the date of separation), minus debts, minus the value of what they owned on the date of marriage (also minus debts on that date). The spouse whose net family property grew more during the marriage owes the other spouse an equalization payment equal to half the difference. Ownership of any specific asset does not automatically change hands; it becomes a debt one spouse owes the other.

There is one important exception to the date-of-marriage deduction: the matrimonial home. A spouse normally gets to deduct what they owned on the date of marriage from their net family property calculation, but that deduction is not allowed for a matrimonial home, even if one spouse owned the home for years before the marriage began. Its full value at separation counts, which is why bringing a paid-off or mostly-paid-off home into a marriage is a classic and expensive trap under this model.

Excluded property, meaning it stays out of the equalization calculation, generally includes gifts and inheritances received during the marriage from a third party, as long as they were kept separate and not mixed into jointly used property. Several other common-law provinces (including Alberta, Manitoba, Saskatchewan, and the Atlantic provinces) use variations on this equalization approach, though the details of exclusions and formulas differ by statute.

British Columbia: Direct Division of Family Property

British Columbia's Family Law Act takes a different approach. On separation, spouses each acquire an undivided half interest in family property, meaning property either spouse owned on the date they began living together (if that property was used for a family purpose during the relationship) or acquired during the relationship. There is no equalization payment to calculate; each spouse simply owns half.

BC also carves out excluded property: property a spouse brought into the relationship, along with gifts and inheritances received by one spouse, stays with that spouse and is not automatically split. But there is a significant catch: the increase in value of excluded property during the relationship is divisible family property, even though the underlying asset itself is not. A house one spouse owned before the relationship stays that spouse's excluded property, but if it doubled in value while the couple lived together, that increase is split.

BC's regime is also the most inclusive on who it covers. Under the BC Family Law Act, two people become "spouses" for property purposes after two years of a marriage-like relationship, married or not. That means unmarried BC couples get the same direct-division property rights as married couples once they clear the two-year threshold, a sharp contrast with Ontario, where common-law partners get no automatic property division at all.

Quebec: The Family Patrimony, Then the Matrimonial Regime

Quebec runs on civil law, not common law, and its property rules on divorce work in two layers.

The first and mandatory layer is the family patrimony (patrimoine familial) under the Civil Code of Quebec. It automatically applies to every married or civilly united couple in Quebec and covers a defined list of assets: the family residences (including a cottage or vacation property used by the family), household furniture that furnishes those residences, family motor vehicles, and the value of retirement benefits accrued during the marriage (QPP or CPP credits, and amounts accrued during the marriage under RRSPs, pension plans, LIRAs, RRIFs, and similar vehicles). These are split equally between the spouses regardless of whose name is on the title or the account, and the family patrimony cannot be contracted out of during the marriage; a marriage contract cannot waive it in advance.

The second layer is the couple's matrimonial regime, which governs everything the family patrimony does not reach. Quebec couples who do not sign a marriage contract choosing another regime default into the partnership of acquests (société d'acquêts), under which property acquired during the marriage through income or effort is shared, while property owned before the marriage or received as a gift or inheritance generally remains separate. Couples can instead choose separation as to property by marriage contract, which keeps assets almost entirely separate outside the mandatory family patrimony.

Quebec's de facto (common-law) couples are excluded from both the family patrimony and the matrimonial regime; property claims between them generally rely on general civil law doctrines like unjust enrichment. Bill 56 created a new "parental union" (union parentale) regime, in force June 30, 2025, which gives unmarried couples who have a child born on or after that date a property regime resembling the family patrimony. It did not create spousal support rights for de facto couples; Quebec remains the only province where de facto spouses have no statutory entitlement to spousal support, a position the Supreme Court upheld in Quebec (Attorney General) v A, 2013 SCC 5 (widely known as "Eric v Lola").

Comparing the Three Models

Pensions Are Divisible in Every Province, But the Mechanics Differ

A pension earned during the relationship is treated as divisible property across Canada, whether it is a workplace pension, the Canada Pension Plan, or Quebec Pension Plan credits. What differs is the process. Ontario's Family Law Act folds the pension's value into the net family property calculation using valuation rules set out in pension-specific regulations. BC's Family Law Act has a dedicated Part 6 on pension division, with its own regulation and administrative process through the pension plan administrator. Quebec includes accrued QPP or CPP credits and amounts accrued under most registered retirement vehicles directly in the family patrimony, administered in part through Retraite Quebec. Federally regulated pensions can also be divided under the federal Pension Benefits Division Act. In every case, only the portion of the pension earned during the relationship is divisible, not benefits earned before it began or after separation.

Debts Are Divided Too

None of these three models looks only at assets. Ontario's equalization formula nets out each spouse's debts and liabilities on both the date of marriage and the valuation date, so debt reduces net family property just as an asset increases it. BC's Family Law Act defines family debt alongside family property and divides debt incurred for a family purpose in roughly the same way it divides property. Quebec's family patrimony calculation deducts debts contracted to acquire, improve, or maintain patrimony property before arriving at the net value to be split. A spouse with more debt is not automatically protected from these rules, and a spouse who carried joint debt should expect it to factor into the final numbers under any of the three systems.

Valuation Dates Differ by Province

When property is valued affects how much is on the table, so each province fixes its own valuation date. Ontario's Family Law Act defines the valuation date as the earliest of several triggering events, most commonly the date the spouses separate with no reasonable prospect of reconciling. BC generally looks to the date of separation to determine what counts as family property, though the value assigned to it can be assessed later in the process, including at trial, unless the parties agree otherwise. Quebec's family patrimony is generally valued as of the date proceedings for separation from bed and board, divorce, or annulment are instituted. None of these dates is the date the divorce itself becomes final, which is a separate, later milestone under the federal Divorce Act.

Limitation Periods: Provinces Set Their Own Deadlines

Waiting too long to bring a property claim can end it entirely, and the clock runs differently in each province.

• Ontario: an equalization claim generally must be started within six years of separation or two years after the divorce is granted, whichever comes first.
• British Columbia: a married spouse must generally start a property, pension, or support claim within two years of the divorce or annulment order; an unmarried spouse must generally start within two years of the date of separation.
• Quebec: family patrimony partition is normally resolved as part of the same court proceeding as the separation, divorce, or annulment itself, rather than as a freestanding later claim; the Civil Code's general prescription rules for personal actions can apply if partition is pursued separately, so this is not a deadline to plan around loosely.

These are general statements of provincial law, not case-specific advice, and each statute has more detail than fits here. Anyone approaching one of these windows should confirm the current deadline against the applicable provincial statute or with a licensed family law professional.

Common-Law Partners Are Often Outside These Property Regimes

A recurring theme across all three provinces is that common-law status does not automatically bring the same property rights as marriage. Ontario common-law partners can qualify for spousal support after three years of cohabitation (or sooner with a child and some permanence to the relationship) but get no automatic equalization of property. Quebec de facto couples get neither statutory support nor the family patrimony, aside from the narrow post-June 2025 parental union property regime for parents of children born after that date. British Columbia is the outlier in the other direction: its two-year marriage-like relationship threshold gives unmarried spouses the same direct property division rights as married spouses. Because the rules vary this much by province and by purpose (support versus property), never assume a common-law relationship carries the same property consequences as marriage; see common-law relationships in Canada for how support and property rules diverge by province.
