More Ontarians are building their families through surrogacy than ever before. But surrogacy law in Ontario is a patchwork of provincial family law rules, federal legislation, and evolving court practice — and getting it wrong can mean the child you've planned and waited for doesn't legally belong to you at birth. This guide explains the legal framework so you can navigate the process with confidence.

The Governing Laws

Surrogacy in Ontario involves at least two layers of law:

The Central Concept: Pre-Conception Agreement

Ontario's CLRA establishes that the intended parents named in a written pre-conception agreement (signed by all parties before conception) are the child's legal parents from birth — not the surrogate.

This is a major shift from older rules. Under the updated framework:

If there is no valid pre-conception agreement, the default rules apply: the birth mother (surrogate) is a legal parent, and the intended parent who did not give birth is not automatically recognized. In that case, a court process is required to establish parentage.

What a pre-conception agreement should cover

A poorly drafted agreement — or no agreement at all — creates serious legal risk. Both parties need independent legal counsel.

Getting a Parentage Order: When and Why

Even with a valid pre-conception agreement, many Ontario families choose to obtain a court-issued parentage order after the child is born. Why?

  1. Certainty and portability: A court order is recognized across jurisdictions in a way that a contract is not. This matters for travel, citizenship, schooling, and medical decisions.
  2. Birth registration: An order allows the intended parents' names to appear on the birth registration from the outset.
  3. International surrogacy: If the surrogacy occurred in another country, Ontario courts may need to make an order recognizing the intended parents' status under Ontario law — which may differ from what the foreign country recognized.

For domestic surrogacy with a valid pre-conception agreement, a parentage declaration can often be obtained on consent before or shortly after birth, with the surrogate's participation.

International Surrogacy: Added Complexity

Many Ontarians use surrogates in countries where commercial surrogacy is legal (the United States, some other jurisdictions). This adds layers:

Finding a Surrogate

Ontario has no formal registry. Most Ontarians connect with potential surrogates through:

Once a match is found, both parties need independent legal advice before any agreement is signed and before medical procedures begin. A surrogate should not sign the pre-conception agreement without their own independent lawyer reviewing it.

Costs: What Can and Cannot Be Reimbursed

Under the AHRA (as implemented through regulations), a surrogate can be reimbursed for expenses that are directly attributable to the surrogacy, such as:

As of writing, the list of reimbursable categories and the documentation requirements are set out in federal regulations — verify the current rules with a surrogacy lawyer before making any payments. Do not pay a base fee or compensation beyond reimbursable expenses.

Frequently asked questions

Does the surrogate have any rights to keep the baby?

If a valid pre-conception agreement is in place under Ontario's CLRA, the surrogate is not a legal parent. She has no parental rights to assert. Without a valid agreement, the birth mother is a legal parent, which is why the agreement must pre-date conception.

Can a same-sex couple use a surrogate in Ontario?

Yes. Ontario's parentage rules apply equally regardless of sexual orientation or gender identity. Up to four intended parents can be recognized under a pre-conception agreement.

What if the surrogate changes her mind during the pregnancy?

If there is a valid pre-conception agreement, the surrogate's change of heart does not alter the legal parentage. Parentage under the CLRA agreement is fixed at the point of the agreement, not the surrogate's wishes post-birth. This is one of the strongest protections the updated CLRA provides.

Do both intended parents need to be biologically related to the child?

No. Genetic connection is not required for intended-parent status under Ontario's CLRA framework. What matters is being named in a valid pre-conception agreement.
