Sponsoring a Child to Canada When the Biological Father is Unknown

21 Jul 2026 4 min read No comments Family Sponsorship Canada
👮‍♂️

If you are sponsoring a child to Canada and the biological father is unknown or unreachable, you cannot simply leave the IMM 5604 form blank. You must provide Immigration, Refugees and Citizenship Canada (IRCC) with strong legal proof, such as a sworn statutory declaration or a sole decision-making (custody) court order, to prove you have the exclusive legal right to remove the child from their home country.

Canadian immigration law prioritises the safety and well-being of children above all else. To prevent international child abduction, Immigration, Refugees and Citizenship Canada (IRCC) strictly enforces rules regarding parental consent. If you are a single parent looking to sponsor your child to live with you in cities like Calgary, Edmonton, or Ottawa, you must prove that no other parent has legal rights to the child.

Usually, this is done by having the non-accompanying parent sign an IMM 5604 form (Declaration from Non-Accompanying Parent). However, when the biological father is genuinely unknown, deceased, or has completely abandoned the family and cannot be located, obtaining this signature is impossible. This guide explains the precise legal steps you must take to satisfy IRCC’s strict requirements. 📍

Step-by-Step Process in Canada

Bypassing the IMM 5604 form requires demonstrating that you have made every reasonable effort to comply with the law, or proving that compliance is legally impossible due to the father’s absence.

Step 1: Obtain the Child’s Official Birth Certificate

The first document an IRCC officer will review is the child’s long-form birth certificate. If the father’s name is listed as “Unknown” or the space is left entirely blank, this is the strongest piece of evidence you can provide. 📄

However, if a man’s name is listed on the birth certificate, IRCC legally assumes he has parental rights. Even if he has never met the child or paid support, his name on that document means you must take further legal action to bypass his required consent.

Step 2: Draft a Statutory Declaration or Affidavit

If the father’s identity is truly unknown but IRCC requests an explanation, you must prepare a formal Statutory Declaration. This is a sworn legal document, signed in front of a notary public or lawyer, detailing the exact circumstances of the child’s birth and the father’s absence. ✍️

The affidavit should explain why the father cannot be contacted, detail any efforts made to locate him, and swear under oath that you have sole care of the child. Lying on a statutory declaration is a serious criminal offence, so the information must be completely factual.

Step 3: Obtain a Sole Decision-Making Responsibility Order

If the father is named on the birth certificate but has disappeared, a statutory declaration may not be enough for IRCC. You will likely need to go to family court in your home country (or in Canada, if applicable) to obtain a formal court order granting you “sole decision-making responsibility” (formerly known as sole custody). 🏛️

The court order must explicitly state that you have the legal right to remove the child from the jurisdiction and relocate them to Canada without the father’s consent. IRCC heavily relies on local family court decisions to resolve custody disputes.

Step 4: Submit a Letter of Explanation to IRCC

When you assemble your Family Class Sponsorship application, include a detailed Letter of Explanation. This letter serves as a roadmap for the immigration officer, guiding them through your evidence. 📩

State clearly why the IMM 5604 form is missing, reference the attached birth certificate or court order, and explain how your documents prove you have sole legal authority over the child. Hiring a Canadian immigration lawyer to draft this letter ensures it meets IRCC’s legal standards.

How Much Does it Cost in Canada?

While the IRCC sponsorship fees remain standard, the legal costs of proving sole custody or drafting affidavits can vary depending on your situation. 💰

  • IRCC Sponsorship Fees: Sponsoring a dependent child currently costs $180 CAD.
  • Notary Fees: Having a Canadian notary public or lawyer swear your statutory declaration usually costs $50 to $150 CAD.
  • Family Court Costs: If you must hire a family lawyer to obtain a sole custody order, legal fees can range from $2,500 to $5,000 CAD or more, depending on the complexity.
  • Immigration Lawyer Retainer: Hiring an expert to manage a complex sponsorship file typically costs between $3,000 and $6,000 CAD.

How Long Does the Process Take?

Standard child sponsorship applications typically take about 10 to 12 months for IRCC to process. However, if your file involves a missing parent and complex legal arguments, processing times can be extended. ⏱️

If IRCC is not satisfied with your initial affidavit, they may issue a Procedural Fairness Letter requesting a formal court order. Securing a court order in a foreign jurisdiction can easily add 6 to 12 months to your timeline, which is why it is best to secure all legal documents before you submit your initial application.

Frequently Asked Questions (FAQ)

Will IRCC reject my application if the father refuses to sign?

If the father is known, has legal rights, and actively refuses to sign the IMM 5604, IRCC will generally refuse the application to prevent child abduction. You must obtain a family court order overriding his refusal before IRCC will grant the visa.

What if the biological father is deceased?

If the father has passed away, you do not need the IMM 5604 form. Instead, you must provide a certified copy of his official death certificate alongside the child’s birth certificate.

Can a Canadian lawyer help me get a foreign custody order?

A Canadian immigration lawyer can advise you on exactly what the court order needs to say to satisfy IRCC. However, you will likely need to hire a local family lawyer in the child’s home country to actually file the court paperwork there.

Do I still need to provide a DNA test?

If you are the biological mother sponsoring the child, IRCC may request a DNA test if the child’s birth certificate is deemed unreliable or if there are concerns about the biological relationship, regardless of the father’s status.
