The Ontario Genealogical Society, operating as Ontario Ancestors since early 2019, is the largest organization devoted to research into family history in Ontario, Canada.  Founded in 1961 as a Registered Charity corporation, the Society has grown by 2020 to include 30 local branches covering all of Ontario and five Special Interest Groups.

Objectives
The objectives of the Society are:
To promote genealogical research
To set standards for genealogical excellence by encouragement and instruction in effective research methods
To make available to those whose ancestors are from Ontario, the knowledge, diversity and comprehensiveness of the genealogical resources in Ontario

Annual conference
Each year, the Society organizes a family history conference in a different part of the province.  In 2018 the Conference was in Guelph, Ontario, in 2019 in London, and the 2020 Conference will be held in Hamilton. Genealogists and family historians from all over North America attend these conferences to exchange information, and to learn about new resources and research techniques. This conference also arranges for information booths from similar organizations, such as the Canadian Friends Historical Association to facilitate networking, as well as exhibits and presentation from commercial providers such as Ancestry, MyHeritage and Family Tree Maker.

Branches
The Ontario Genealogical Society's branches are spread all over Ontario. Each branch takes responsibility for carrying out the Society's objectives in local communities. Members of the public can find information about the branches nearest them by checking the section of the Ontario Ancestors website devoted to Branches/SIGs. https://ogs.on.ca/branchessigs/branch-sig-locator/
