The short answer
Every Canadian province shares the property built during the relationship, but the mechanics differ. Ontario equalizes the growth in each married spouse's net worth. BC divides family property equally and excludes what each person brought in, while sharing its growth. Alberta divides property under its Family Property Act, which now covers adult interdependent partners as well as married spouses. Quebec applies a mandatory family patrimony to married spouses. Whether common-law partners share property depends heavily on the province, and there are deadlines for making a claim.
Dividing property is usually the most financially consequential part of a separation. The family home, pensions, savings, investments and debts all have to be accounted for. It is also where people feel most exposed, especially if one partner handled the money. You do not need to become an expert in property law, but knowing which model applies to you helps you ask the right questions and spot an offer that does not add up.
What most people do not realise is how much the rules depend on your province and on whether you were married. Here is how the main systems work, and what you actually need to do.
The core principle: what you built together gets divided
Across Canada, the general idea is that property built up during the relationship, through the efforts of either or both partners, is shared at the end of it. What you brought in before the relationship, and gifts or inheritances given to you personally by someone outside it, are often protected in some way. The mechanics differ by province, and the exceptions matter, but the underlying idea is consistent.
Two dates drive almost everything: the start of the relationship (marriage or moving in together, depending on the province) and the separation date, which is usually the date assets and debts are valued.
Ontario: equalization of net family property
Ontario uses the equalization model under the Family Law Act. You do not divide each asset. You equalize the growth in each married spouse's net worth during the marriage.
- Each spouse calculates their net family property (NFP): the value of everything they own at the valuation date (usually separation), minus their debts at that date, minus the net value of what they owned on the date of marriage, with some exceptions.
- The spouse with the higher NFP pays the other half the difference. This is the equalization payment.
Example
Spouse A's NFP is $300,000. Spouse B's NFP is $100,000. The difference is $200,000, so Spouse A owes Spouse B $100,000 to equalize.
You do not have to split every asset down the middle. You can satisfy the equalization payment by transferring one asset, such as part of an RRSP, the house or cash. That flexibility is useful when one person wants to keep a particular asset.
The matrimonial home in Ontario
The family home is treated differently from other assets. Regardless of whose name is on title, both married spouses have an equal right to live in the matrimonial home, and neither can sell or mortgage it without the other's consent while the marriage lasts.
In the NFP calculation there is an important asymmetry. If you owned the home before the marriage and it is still the matrimonial home when you separate, you cannot deduct its date-of-marriage value. Its full value goes into your NFP. This surprises a lot of people.
Excluded property in Ontario
Some property is left out of NFP, including gifts and inheritances received from a third party during the marriage, certain personal injury damages and life insurance proceeds, and property you can trace to those sources. Exclusions can be lost: a gift or inheritance used to buy, pay down or improve the matrimonial home generally loses its protection. Keep records of where money came from.
A court can order an unequal split only where an equal one would be unconscionable, which is a high bar.
Common-law couples in Ontario
Ontario's equalization regime applies only to married spouses. Common-law couples, however long they have been together, have no automatic property sharing under the Family Law Act. A claim has to be based on doctrines such as unjust enrichment, which requires showing that one partner was enriched at the other's expense. That usually means negotiation backed by legal advice, or a court case. See our common-law separation guide.
British Columbia: equal division of family property
BC's Family Law Act presumes equal division of all family property, which is broadly everything either spouse owns at the date of separation, with excluded property set aside.
Excluded property under section 85 includes:
- Property a spouse owned before the relationship
- Gifts and inheritances to one spouse during the relationship
- Certain insurance proceeds and court awards
- Property bought with excluded property, if it can be traced
The excluded property itself stays with its owner, but any increase in its value during the relationship is family property and divided equally. If you inherited a rental property worth $400,000 before the relationship and it is worth $650,000 at separation, the $400,000 is excluded and the $250,000 increase is shared.
A court can divide unequally only where equal division would be significantly unfair, for example in a very short relationship.
The mixing problem
Excluded property can lose its protection if it gets mixed with family money so thoroughly that it cannot be traced. A common example: an inheritance deposited into the joint account used for everyday spending. Years later, can you show it is still there? If not, the exclusion may be lost. Keep excluded money separate and document where it came from.
Common-law couples in BC
Under BC's Family Law Act, people who have lived together in a marriage-like relationship for at least two years are spouses for property division purposes. After two years, unmarried couples have the same property rights and obligations as married couples.
Alberta: Family Property Act
Alberta's Matrimonial Property Act was renamed the Family Property Act on January 1, 2020, and its rules now apply to adult interdependent partners as well as married spouses, according to the Government of Alberta. The general principle is that property acquired during the relationship is divided equally unless that would be unjust. Certain property, such as property owned before the relationship and gifts and inheritances from third parties, is exempt up to its value at the relevant date, while growth can be shared.
Adult interdependent partners generally have two years from when they knew or should have known the relationship ended to make a claim. See our glossary entry on adult interdependent partners.
Quebec: family patrimony
Quebec's Civil Code creates a family patrimony for married spouses and civil union partners. It includes the family residences, household furniture, family vehicles and pension rights accumulated during the marriage, and its value is generally shared equally regardless of whose name is on title. Spouses cannot opt out of it before separation. Other property is divided according to the couple's matrimonial regime, which for most marriages is the partnership of acquests unless a marriage contract says otherwise.
Unmarried (de facto) couples in Quebec historically had no property sharing regime. That changed for parents of children born or adopted since the end of June 2025: they are now in a parental union with its own patrimony covering the family residence, furniture and vehicles, as explained by Éducaloi. Check the Quebec hub for details.
Other provinces and territories
Each has its own statute. Saskatchewan and Manitoba extend property sharing to many common-law partners who meet cohabitation requirements. In most Atlantic provinces the statutory rules apply mainly to married spouses, although Nova Scotia also covers registered domestic partners. Unmarried partners outside these regimes generally rely on unjust enrichment claims. Your provincial hub summarises the rules where you live.
In the US? States use either community property (generally equal division of property acquired during the marriage) or equitable distribution (a fair division, not always equal). See the glossary entries for community property and equitable distribution.
What are the deadlines for a property claim?
Property claims have time limits, and missing one can cost you your claim. In Ontario, an equalization claim must generally be started within two years of a divorce or six years of separation, whichever comes first. In BC, the general limit is two years after a divorce order for married spouses, or two years after separation for unmarried spouses. Alberta adult interdependent partners generally have two years from the end of the relationship. If you are anywhere near a deadline, speak to a family lawyer now, even if you are still negotiating.
What counts as property?
Courts think more broadly than real estate and bank accounts. Property usually includes:
- The family home and any other real estate, including cottages and rentals
- Bank accounts, savings and investment accounts
- RRSPs, TFSAs and other registered plans
- Pensions, including defined benefit plans and CPP credits
- Vehicles, boats and recreational equipment
- Business interests and shares
- Life insurance with a cash value
- Cryptocurrency and other digital assets
- Valuable personal property such as art, jewellery and collections
Don't overlook pensions. In many separations, the pension is one of the largest assets. Defined benefit pensions are often undervalued because there is no obvious balance, and you need a valuation from the plan administrator or an actuary. Read pensions at separation for how they are valued and divided.
Is debt divided at separation too?
Debts built up during the relationship for family purposes are part of the picture. In Ontario they reduce each spouse's NFP; in BC, family debt is shared like family property. Mortgages, credit cards and lines of credit all need to be allocated.
One critical point: dividing debt in a separation agreement does not bind your lenders. If your agreement gives your former partner the joint credit card and they do not pay, the bank can still come after you. Removing your name from joint accounts and loans is a separate step, and lenders do not have to agree to it. Read joint debt at separation for how to protect yourself.
Getting a clear picture before you negotiate
You cannot divide fairly what you have not fully disclosed. Both of you are legally required to make full financial disclosure, and courts take it seriously when it is done badly or dishonestly. Start with:
- Statements for every account, investment and registered plan, at the start of the relationship (if relevant), the separation date and now
- Property valuations or appraisals
- Mortgage statements and loan balances
- Pension statements and any valuations
- Proof of property owned before the relationship and of gifts or inheritances received during it
The financial disclosure checklist lists everything, and FairWell's asset division tools help you build a complete inventory and see how your province's rules apply to it.
What to do this week
- Confirm which rules apply to you: your province, whether you were married, and how long you lived together.
- Write down your key dates: start of cohabitation, marriage, and separation.
- List every asset and debt in either name, with an approximate value.
- Gather proof of anything you brought into the relationship or inherited, and keep it separate.
- Check whether any deadline for a property claim is approaching, and if so, book a lawyer consultation now.
Common questions
Is property always split 50/50 in Canada?
The starting point is usually equal sharing of what was built during the relationship, but how that is calculated differs by province, excluded property is treated differently, and courts can depart from equal sharing in limited circumstances.
Do common-law partners get half the property?
It depends on the province. In BC, after two years together, unmarried partners have the same property rights as married spouses. In Ontario they have no automatic property sharing and must rely on claims such as unjust enrichment. Alberta's Family Property Act covers adult interdependent partners.
Is my inheritance protected?
Often, but not always. Inheritances received during the relationship are commonly excluded, but they can lose that protection if they are mixed with family money or, in Ontario, put into the matrimonial home. Growth in value may also be shared in some provinces.
What date is used to value our property?
Usually the separation date, though some provinces allow other dates in some circumstances. Agreeing the separation date early avoids one of the most common disputes.
Is there a deadline to make a property claim?
Yes. In Ontario, generally two years after divorce or six years after separation, whichever is earlier. In BC, generally two years after divorce for married spouses or two years after separation for unmarried spouses. Check your province's rule early.
