Once you have obtained the names of your natural parents or the child you lost to adoption, some useful tools for your search include:

  • Searching for names using Google or Facebook
  • Looking in online phone directories including www.canada411.ca and www.pipl.ca
  • Your original birth record indicates where your natural mother and father were born. You can use the phone directory for that city to contact them or other family members to find out where they might currently be living.
  • Henderson Directories (“City Directories”) for the city you were born in, or in which your natural parent was born, and for occupations.  They can also provide relevant older information on names, addresses, and occupations dating back to 1905. Many cities across Canada had these directories in addition to phone-books. Check local libraries and online sources (e.g., University of Alberta) for copies.
  • Check adoption notices in the newspaper after date of completion of adoption.  Also check birth notices that do not mention the time of birth or doctors involved, these are sometimes disguised adoption notices.
  • Check birthday wishes in the paper
  • Peruse highschool and yearbooks for appropriate years
  • Check Obituaries

Ontario’s Open Records Campaign

In 2009 Ontario became the fourth province in Canada to approve open records.  Against much opposition by open records groups, this legislation was later amended to include veto provisions after a legal challenge by three adoptees and one biological father.
