Key takeaways
  • Ontario adoptive parents can be a couple or a single person, and spouses can apply jointly.
  • A spouse of a child's parent can apply for a family adoption order, and the parent stays a legal parent.
  • Some couples become legal parents without adoption, through the Children's Law Reform Act rules on assisted reproduction and surrogacy.

If you and your partner want to raise a child together, Ontario offers more than one legal path. You might adopt through a children's aid society, use a private or international process, adopt your partner's child, or become legal parents from birth through a written agreement or the assisted reproduction rules.

Which path fits depends on how the child came or will come into your family. This article lays out the main options and the rules that matter. It is general information, and a lawyer can confirm how it applies to your family.

Who can adopt in Ontario

Adoptive parents must be Ontario residents and can be a couple or a single person. An application may be made by one individual or jointly by two individuals who are spouses of each other.

No adoption order may be made on the application of a person who is not an Ontario resident, or for the adoption of a person who is not an Ontario resident. If one partner applies alone and is a spouse, the other spouse must give written consent.

The main adoption routes

Ontario recognizes four main types of adoption: public, private domestic, international, and adoption of a stepchild or relative who lives in Ontario. Ontario says the process can take at least a year and sometimes longer.

RouteKey points
Public (children's aid society)No cost to adoptive parents; a SAFE homestudy and 27-hour PRIDE training are required.
Private domesticLicensees generally charge $15,000 to $30,000, with the homestudy and training extra.
InternationalLicensed agencies usually charge $20,000 to $50,000, plus homestudy, training and travel.
Stepchild or relativeMade directly through the Ontario court, with no licensee needed.

For public adoption, matching typically takes six months to two years or longer, followed by an adjustment period of at least six months before the court finalizes the adoption. These are general ranges, not fixed amounts or promises.

Adopting your partner's child

The court may make a family adoption order on the application of the child's relative, the child's parent, or the spouse of the child's parent. A placement with the spouse of the child's parent is exempt from the usual placement restrictions, as long as the child lives in Canada and the placement is within Ontario.

In a stepparent adoption, the parent who is married to or partnered with the stepparent stays a legal parent. The adoption does not remove them. Any other legal parent would generally need to consent, or the court would need to dispense with that consent.

Whether adoption is even necessary depends on how the child was conceived, which the next section explains.

Becoming legal parents without adoption

Parentage for children who are not adopted is decided under the Children's Law Reform Act (CLRA), and for adopted children under the CYFSA. Several CLRA rules matter to couples building a family.

The spousal rule does not apply to surrogacy or posthumous conception. A declaration that would create more than two parents generally must be sought within one year of the birth, must include all parents as parties, and needs proof that they intended before conception to be parents together.

What to do next

Frequently asked questions

Can a same-sex couple adopt jointly in Ontario?

An adoption application may be made jointly by two individuals who are spouses of each other. Adoptive parents can also be a single person.

Does my spouse need to adopt our child if we used a sperm donor?

Often not. When a child is conceived through assisted reproduction or insemination by a sperm donor, the birth parent's spouse is a legal parent without adoption. That does not apply if the spouse did not consent before conception or withdrew consent, or in surrogacy or posthumous conception.

If I adopt my spouse's child, does my spouse stop being a parent?

No. In a stepparent adoption, the parent who is married to or partnered with the stepparent stays a legal parent.

Can more than two people be legal parents?

Yes, in some cases. Up to four parties can sign a pre-conception parentage agreement, and surrogacy can involve up to four intended parents. A court declaration creating more than two parents has strict conditions and a one-year timeline unless the court orders otherwise.
