Key takeaways
  • Equalization compares each spouse's net property at separation with the net value at marriage, and the larger share pays half the difference.
  • After a long marriage, the length of cohabitation and each spouse's roles are specific factors in spousal support.
  • The family home is shared in full even if it was owned before marriage, unless you agree otherwise.
  • Time limits apply to equalization claims, so do not wait on the paperwork.

After many years together, finances are often tangled: a home, pensions, savings, maybe a business or a cottage. You may also have spent years with one spouse earning more while the other managed the household or supported a career. Divorce law in Ontario has specific rules for each of these.

This article walks through how equalization, the family home and spousal support are generally approached, and what the process looks like. It is general information; the outcome in any case depends on its facts.

The legal basics of divorce

To start a divorce in Ontario, at least one spouse must have been habitually resident in the province for at least one year immediately before the proceeding begins. The only ground is marriage breakdown, shown by living separate and apart for at least one year.

The court also has a duty to satisfy itself that there is no possibility of reconciliation, unless the circumstances make that inappropriate. If you tried to get back together, the one-year period is not broken if you lived together for no more than 90 days in total and reconciliation was the main purpose.

How equalization works after many years

Net family property is the value of what you own on the separation date, minus debts and excluded property, less the same net value at the date of marriage. A negative result counts as zero. The spouse with the larger amount pays half the difference as an equalization payment.

In a long marriage, the starting value at marriage is often small compared with what you own at separation, so most growth is shared. Excluded property includes gifts and inheritances from someone other than your spouse received during the marriage (other than the family home), insurance money from a death, personal injury money and anything you both agree to exclude. An Ontario pension also counts as property, and you ask the pension administrator for its value.

Inheritance from a parent during the marriageGenerally excluded, other than the family home

Mortgage on the homeDeducted at separation, not in the marriage-date calculation

Unequal division is allowed only in very special situations where equal division would be extremely unfair.

The family home

Only the house and a small surrounding area count in the family home rule, and its full value is shared even if one spouse owned it before the marriage. Whether a cottage or other property qualifies depends on how it was used, so ask a lawyer about it.

A married person can ask the court to let them stay in the home and require the other spouse to leave, even if the spouse owns it. The judge looks at past violence, whether there is another suitable place to live, the children's interests and both parties' finances. Whether there are other steps to protect your position on the home depends on your situation, so it is worth confirming with a lawyer.

Spousal support after a long relationship

The court may consider spousal support by looking at each spouse's condition, means, needs and other circumstances, including the length of cohabitation, the functions each performed during cohabitation, and any order, agreement or arrangement about support. A long marriage and years spent on household or family work are therefore directly relevant.

How long support lasts and how much is paid depend on the particular facts, including incomes, health and retirement plans. A lawyer can estimate a realistic range once they see your financial information.

Steps, paperwork and timing

Agreements reached at a conference are written as Minutes of Settlement. A temporary order, for example on support or who lives in the home, can stay in place while the case continues. Equalization claims must be brought within six years of separation or two years after the divorce is final, whichever comes first. The divorce itself takes effect 31 days after the order.

What to do next

Frequently asked questions

Is everything split equally after a long marriage?

Equalization pays half the difference between the two spouses' net family property, not half of every asset. Unequal division is allowed only where equal division would be extremely unfair.

How long will I have to pay or receive spousal support?

The court looks at each spouse's means, needs and circumstances, including the length of cohabitation and roles during it. The duration depends on your facts, so a lawyer should review them.

What happens to my inheritance?

Property inherited from someone other than your spouse during the marriage is generally excluded, other than the family home. How it was used can matter, so keep records.

Is there a deadline to claim equalization?

Yes. An application must be made within six years of separation or two years after the divorce is final, whichever comes first.
