Adoption Disclosure

Adoption disclosure refers to the official release of information and records to adopted persons and birth parents. Adopted adults and parents now have more access than ever to information. If your adoption was finalized in Ontario, adopted adults and birth parents can apply for information at Service

If you are an adopted person who is over the age of eighteen, this may include original birth information such as your name at birth and the name of one or both of your birth parents. If you are a parent, once the child is nineteen years old, you may learn the name they were given at the time of their adoption.

For adoptions prior to September 2008, adopted adults and birth parents can file a disclosure veto if they do not want their identifying information released.  Disclosure vetoes do not apply to adoptions which were finalized as of September 1, 2008.

For adoptions finalized after September 1, 2008, adopted adults and birth parents who are interested in contact can file a ‘notice of contact preference’ specifying how they wish to communicate.  If they prefer not to be contacted once their identifying information has been released, they can file a ‘no contact notice.’

Adults who were adopted, birth parents, adoptive parents and birth relatives can also apply for other types of adoption information and services, which include:

  • Non-Identifying Information
  • Severe Medical Searches
  • Placing a Name on the Adoption Disclosure Register
  • Copies of Adoption Orders
