The Ontario Genealogical Society was formed in 1961 to encourage, bring together, and assist those interested in the pursuit of Ontario family history and to preserve our Ontario genealogical heritage, we seek to be recognized as the authority and leader in all aspects of Ontario-related family history research, preservation, and communication. We have 29 Branches as well as six Special Interest Groups (SIGs) representing both geographic and research areas that shape Ontario.  In 2019, we introduced a new brand name and logo to help differentiate us from other genealogical societies. The name Ontario Ancestors provides a more immediately recognizable name to the family history community, while the logo itself incorporates our legal and historical identity as The Ontario Genealogical Society.  You will see both of these names used in connection with our organization from time to time.



eWeekly:  The eWeekly newsletter provides information about upcoming events and genealogical news from both The Ontario Genealogical Society and beyond. It is available to members and non-members.  The newsletter will be sent to your inbox on Saturday mornings. Please subscribe today by filling out the Subscribe form at the bottom left side of the home page.

Social Media:  Our Facebook page Ontario Ancestors and our Twitter page @OntGenSociety are great places to ask questions and network with people across the globe.  Many of our Branches and Special Interest Groups also have Facebook and/or Twitter pages where you can connect with others researching a specific geographical or special interest area.  You can find links to their pages on the Branch and SIG’s websites

Families:   Our quarterly Journal is packed with stories, articles and other items that share breakthroughs, and resources from fellow genealogists. The content of each issue is unique and can include narrative family histories, book reviews, resource overviews and more. We are always looking for submissions.

Members’ Corner:  This section of the website can be found under the Resource Tab. This is where you will find all the members’ only content, offers, and resources.  Some of the resources are explained below.

IOOF Papers:  Between 1875 and 1929, the Independent Order of Odd Fellows operated a life insurance program. Approximately 60,000 men from all across Canada applied. The program was eventually operated by Empire Life, who held all the application forms and these applications forms were transferred to the Society. Volunteers spent nearly four years indexing these forms. We have indexed the following: check public link and see where it goes

  • applicant’s last and first names,
  • date of birth,
  • community in which the applicant resided at the time of application,
  • province, and
  • policy number

The index can be found in the Members’ Corner Section of the Resource Tab under IOOF Insurance Papers Database. We have scanned approximately 50% of these applications to date. If a scan exists, Members may download the image at no cost by clicking the Download File link. If no link is available, a scan of that application can be requested from the Society Office by contacting officeadmin@ogs.on.ca.

Ongoing Projects:  The Society takes on projects both large and small that will be of value to genealogists and family researchers.  Some are realized by the coordinated efforts of Branches; some are done by a group of volunteers. All provide information needed by genealogists that is unlikely to be found elsewhere. The Society and its dedicated volunteers are one of the major suppliers of Ontario genealogical information. Volunteers make these results occur, and we are always seeking more volunteers. Many of these projects can be done at a distance. If one of the current projects interests you, please contact the Society Office to find out how you might be able to help.
