- Ontario law presumes a person is a child's parent in listed cases, such as being the birth parent's spouse at the birth or living with them in a conjugal relationship before it.
- Any person with an interest can ask the court for a declaration that someone is, or is not, a child's parent, except for adopted children.
- Once parentage is settled, parents have an equal right to decision-making responsibility whether or not they were married, and can apply for a parenting order.
You may be a child's father or other parent, but your name is not on the birth certificate. Or someone may be disputing whether you are a parent at all. Either way, it can feel like you have no footing when decisions are being made about the child.
Ontario law has rules for who is treated as a parent and a way to ask a court to decide when that is unclear. This article explains those rules in plain language, why they matter, and the basics of what gets filed afterwards.
Who the law treats as a parent
The birth parent is a parent of the child and must be recognized in law as one. Surrogacy is the exception to that rule.
For other people, the Children's Law Reform Act (CLRA) sets out presumptions. A person is presumed to be the parent of a child conceived through sexual intercourse in listed cases. A presumption is a starting point the law accepts unless it is challenged successfully.
The three common presumptions
Under the CLRA, the listed cases include the following:
- Being the birth parent's spouse at the time of the birth.
- Living in a conjugal relationship with the birth parent before the birth.
- Having certified the child's birth as a parent under the Vital Statistics Act.
These matter most to unmarried fathers and other parents. If you were never married to the birth parent, living together in a conjugal relationship before the birth can still put you within the presumption.
When a presumption can be challenged or does not apply
A presumption is not the end of the question. It can be rebutted on a balance of probabilities. In plain words, a balance of probabilities means something is more likely than not. Who needs to prove what in your situation depends on the facts, so it is worth confirming with a lawyer.
There is also an exception. If more than one person would be presumed to be the parent, no presumption of parentage arises at all. In that situation, the question may need to go to a court.
Asking the court for a declaration
If you are not on the birth certificate, or parentage is disputed, any person with an interest may apply to court for a declaration that a person is, or is not, a parent of the child. So the application can be brought to confirm parentage or to say someone is not a parent.
This route does not apply to adopted children.
The details of how evidence is gathered and how the record is corrected afterwards depend on your situation. A lawyer can explain what is likely to be needed in your case.
Why parentage matters, and what is filed next
Parents have an equal right to decision-making responsibility for the child, whether or not they were ever married. A parent may also apply to court for a parenting order covering decision-making responsibility and parenting time.
One exception is worth knowing. If the parents live apart and the child lives with one parent with the other's consent, implied consent or acquiescence, the other parent's right to exercise decision-making responsibility is suspended until a separation agreement or court order says otherwise. Their entitlement to parenting time is not suspended.
Parenting time includes the right to visit with and be visited by the child, and to make inquiries and receive information about the child's well-being.
On the filing basics, an application must include an affidavit with your proposed plan for the child's care and upbringing and details of any earlier family or criminal proceedings. Ontario's guidance says parents applying file Form 8 and Form 35.1 (Part A).
What to do next
- Gather anything showing your relationship with the birth parent before the birth, such as shared addresses or records.
- Find out whether you certified the birth or are named on any registration.
- Write down a simple plan for the child's care and upbringing, since the court application needs one.
- Collect details of any earlier family, child-protection or criminal proceedings involving you or the child.
- Speak with a family lawyer before filing, especially if more than one person could be presumed a parent.
Frequently asked questions
Can I be a legal parent if I am not on the birth certificate?
Possibly. The law presumes parentage in listed cases, such as living in a conjugal relationship with the birth parent before the birth. If it is disputed, any person with an interest can ask the court for a declaration.
Do unmarried parents have the same decision-making rights?
Yes, parents have an equal right to decision-making responsibility whether or not they were married. That can be suspended if the child lives with the other parent with your consent, implied consent or acquiescence, until an agreement or order says otherwise.
Can the presumption of parentage be challenged?
Yes. It can be rebutted on a balance of probabilities. If more than one person would be presumed to be the parent, no presumption arises.
Does a declaration of parentage work for adopted children?
No. The court application for a declaration of parentage does not apply to adopted children.
