Almost every step-parent adoption in Ontario turns on one question: will the child's other birth parent sign a consent? If they will, the file is paperwork and a short hearing. If they will not, you are asking a judge to dispense with that consent, which is a different case entirely.

Ontario adoption law sits in the Child, Youth and Family Services Act. A judge cannot make an adoption order without the written consent of each person who is legally the child's parent, unless the court dispenses with that consent or the parental relationship has already been ended. So the first job is factual, not legal: work out who is legally a parent of this child, and find out whether that person will sign.
Where the other parent agrees, the rest is procedure. Consent is given in a prescribed form, and the person who gave it can withdraw it in writing within 21 days. A family adoption application cannot even be started until that 21-day period has expired, so build it into the timetable — and a later withdrawal, which the court can permit in some circumstances, resets the file and the cost.
Where the other parent refuses, or cannot be found, you bring a motion inside the adoption proceeding asking the court to dispense with consent. The test is not a closed list of grounds: under section 181 the court may dispense with a parent's consent where it is satisfied both that doing so is in the child's best interests and that the parent has had notice of the proposed adoption and of the motion to dispense with consent, or that a reasonable effort was made to give that notice. Evidence carries this motion: dates, support records, unanswered messages, and proof of what you did to search.
The child gets a say too. Ontario requires the written consent of a child who is seven or older, and in every application the court must inquire into the child's capacity to understand it, take the child's views and wishes into account according to age and maturity, and hear the child where it is practical to do so. An older child who objects generally ends the application, whatever the adults have agreed between themselves.
The order does not add you to the child's life alongside the other birth parent. It replaces that parent. On the day the order is made, their legal relationship with the child ends, and every parenting time, decision-making and contact order attached to it ends with it. There is no partial version, and no route back if the adults fall out later.
Support follows parentage. Going forward the other birth parent stops owing child support, and you start — including if your relationship with the child's other parent ends after the adoption. Families regularly learn this after the order is made rather than before. If support was ordered and never paid, ask specifically what happens to the arrears that already built up.
Inheritance follows as well. For Ontario intestacy purposes an adopted child is treated as the child of the adopting parents, so the child no longer inherits automatically from the birth parent's side of the family. If grandparents on that side want the child to receive something, it has to be written into a will. That change of status comes from section 217 of the <a href="https://www.ontario.ca/laws/statute/17c14">Child, Youth and Family Services Act, 2017</a>, which redraws the child's family relationships for all purposes of law; the <a href="https://www.ontario.ca/laws/statute/90s26">Succession Law Reform Act</a> then distributes an intestate estate along those redrawn lines.
The order can change the child's surname at the same time, which is why most families deal with the name inside the adoption rather than running a separate <a href="/changing-childs-name-lawyer-ontario">child name change application</a>. A new birth registration is issued afterwards, and the replacement birth certificate is what schools, passport applications and health records eventually run on.
Adoption is heard in the Ontario Court of Justice across most of the province, and in the Family Court branch of the Superior Court of Justice in the regions that have one. The hearing itself is usually brief: the judge reads the record, may speak with an older child, and makes the order. Almost all of the elapsed time happens before that morning.
A step-parent adoption does not normally require an assessment by an adoption practitioner. Where the child lived in Canada before the adoption, the Act leaves the report on the child's adjustment in your home to the court's discretion, and Ontario's guidance is that you need one only if the judge requires it. What the rules do require is sworn evidence with a police record check attached, from you and from any other adult in the home who is not the child's parent, obtained within six months before the application starts. Ask what your court expects first.
The application package pulls together the step-parent's sworn affidavit with its record check, a certified copy of the child's statement of live birth, proof of the marriage or conjugal relationship, the consents — including the consent of your spouse, the child's parent — any report the court has ordered, and any motion to dispense with consent. Files come back for small reasons: an unsigned consent, a stale record check, a birth certificate that does not match the registration. Assemble it once, properly.
We quote family work as a flat fee rather than an hourly estimate that moves — our uncontested divorce is $1,693.87, taxes included, and an adoption file is priced in writing before we open it. The <a href="/pricing">pricing page</a> lists what is included and what is billed as a disbursement at cost. Background on the process sits in our <a href="/articles/adoption-ontario-step-parent-how-it-works">step-parent adoption guide</a> and the rest of our <a href="/family">family law practice</a>.
Yes, unless the court dispenses with it or that parent's legal relationship with the child has already ended. Consent is the normal route and it has to be in writing, in the prescribed form. Where consent is refused or impossible to obtain, you bring a motion within the adoption proceeding and ask the judge to proceed without it.
You can still apply, but you have to show the court what you did to find them. Document the searches: last known addresses, relatives contacted, employers, social media, any court or support records. A judge deciding whether to dispense with consent wants evidence of genuine effort, not an assertion that the parent is out of touch.
Going forward, yes. Once the adoption order is made that parent is no longer the child's parent in law, so no further support accrues and any existing support order falls away. Arrears that built up before the order are a separate question with its own answer, so raise them with your lawyer before you file rather than after.
The controlling factors are the consent and anything the court asks for beyond the standard material. A file with a signed consent, the 21-day withdrawal period run out and nothing further ordered moves at the pace of the court's scheduling. A file that needs a motion to dispense with consent adds an evidentiary step and a contested hearing. Your lawyer confirms the expected schedule in writing when the file opens.
Yes. The adoption order can direct the child's new name, and a new birth registration is issued afterwards. Doing it this way avoids a separate application and avoids needing the other birth parent's consent to the name, which the adoption order itself has already displaced. Tell your lawyer the exact spelling you want before the order is drafted.
