When a marriage breaks down, most people in Ontario think of divorce. But in some situations, the law treats the marriage as if it was never valid in the first place. That is called an annulment. Understanding the difference between annulment vs divorce matters, because the grounds, the process, and the effect on your status are not the same.
This guide explains how annulment works in Ontario, when it is available, and why many people who ask about annulment end up applying for a divorce instead.
What Is the Difference Between Annulment and Divorce?
A divorce ends a valid marriage. The law accepts that you were legally married, and the court dissolves that marriage from the date of the divorce order.
An annulment (also called a declaration of nullity) is a court declaration that the marriage was never legally valid. Instead of ending the marriage, the court finds that a legal defect existed at the time of the wedding.
| Divorce | Annulment | |
|---|---|---|
| What it does | Ends a valid marriage | Declares the marriage was never legally valid |
| Grounds | Breakdown of the marriage (usually one year of separation) | A legal defect at the time of marriage |
| Waiting period | Usually one year of separation | No one-year separation requirement |
| How common | Very common | Rare; strict legal tests apply |
| Support and property | Available under Ontario law | May still be available in many cases |
Grounds for Annulment in Ontario
An annulment is only available when there was a serious problem with the marriage from the start. The length of the marriage, unhappiness, or the fact that one spouse married for immigration reasons are not, by themselves, grounds for annulment. Recognized grounds include:
1. One Spouse Was Already Married
If one spouse was still legally married to someone else at the time of the wedding, the second marriage is not valid. A person must be divorced, or their previous spouse must have died, before they can legally marry again.
2. Lack of Capacity or Consent
Both spouses must understand the nature of marriage and freely agree to it. A marriage may be annulled if a spouse lacked the mental capacity to consent, or was so intoxicated by alcohol or drugs that they could not understand what they were doing.
3. Duress, Fear, or Fraud
A marriage entered into because of threats, serious pressure, or fear may be annulled, because the consent was not genuine. Fraud can also be a ground, but usually only fraud about the identity of the person or the nature of the ceremony itself, not lies about wealth, background, or intentions.
4. The Spouses Are Too Closely Related
Under the federal Marriage (Prohibited Degrees) Act, people cannot marry if they are related by blood or adoption as siblings (including half-siblings) or in a direct line, such as parent and child.
5. Age Requirements Were Not Met
The legal age requirements for marriage must be met. In Ontario, a person under 18 needs parental consent under the Marriage Act, and federal law sets an absolute minimum age of 16.
6. Inability to Consummate the Marriage
One of the most commonly used grounds in Ontario is non-consummation. This applies where one spouse is unable to have sexual intercourse with the other because of a physical or psychological incapacity. A simple refusal, or a lack of opportunity, is usually not enough. Ontario courts have granted annulments where a spouse’s severe anxiety about physical intimacy made consummation impossible.
Void vs Voidable Marriages
Lawyers often divide invalid marriages into two groups:
- Void marriages were never valid at all, for example where one spouse was already married or the spouses are too closely related.
- Voidable marriages are treated as valid until a court annuls them, for example where the marriage was never consummated because of incapacity.
The difference can affect who may bring the application and what evidence the court needs. A family lawyer can tell you which category your situation falls into.
How Do You Get an Annulment in Ontario?
A civil annulment is granted by the court, usually the Superior Court of Justice. The spouse asking for the annulment must file an application, serve the other spouse, and prove the ground for annulment with evidence. Because annulments are rare and the legal tests are strict, the court will look closely at the facts.
There is no one-year separation requirement for an annulment, which is why some people ask about it when they want to end a very short marriage quickly. However, if the facts do not meet one of the legal grounds, the court will not grant it, and a divorce may be the only option.
Does an Annulment Affect Support and Property?
Many people assume that if the marriage is annulled, there are no financial consequences. That is not always true. Ontario’s Family Law Act includes in its definition of “spouse” a person who entered into a void or voidable marriage in good faith. This means claims for spousal support, property division, and the matrimonial home may still be possible after an annulment.
Children are not affected by the annulment of their parents’ marriage. Both parents remain responsible for child support, and parenting arrangements are decided based on the best interests of the child.
Religious Annulment vs Civil Annulment
A religious annulment, or a religious divorce such as a talaq or khula, does not end a marriage under Ontario law. Only an Ontario court can grant a civil annulment or a divorce. If you were married in a civil ceremony or a registered religious ceremony, you will usually need a civil divorce or annulment to be legally free to remarry, even if your faith community has already recognized the end of the marriage.

Annulment or Divorce: Which Is Right for You?
An annulment may be worth exploring if:
- your spouse was already married when you married,
- you were forced or pressured into the marriage,
- a spouse lacked the capacity to consent, or
- the marriage could not be consummated because of an incapacity.
In most other situations, including short marriages that simply did not work out, a divorce is the correct route. Most divorces are based on one year of separation, and you can start the paperwork before the year is over.

Frequently Asked Questions
How long does an annulment take in Ontario?
It depends on whether the other spouse agrees and how much evidence is needed. Because there is no one-year separation requirement, an annulment can sometimes move faster than a divorce, but contested annulments can take longer.
Can I get an annulment because my marriage was very short?
No. The length of the marriage is not a ground for annulment. You must prove a specific legal defect, such as an existing marriage, lack of consent, or inability to consummate.
Can I get an annulment if my spouse married me for immigration?
Generally no. A spouse’s reasons or motives for marrying are not, on their own, grounds for annulment. A divorce is usually the appropriate route in these cases.
Is a religious annulment enough to remarry in Ontario?
No. A religious annulment or religious divorce has no legal effect in Ontario. You need a civil annulment or divorce from an Ontario court before you can legally remarry.
Can I still claim support after an annulment?
Possibly. Ontario’s Family Law Act can treat a person who married in good faith as a spouse, even if the marriage was void or voidable, so support and property claims may still be available.
