What We Do

Preserving, promoting, and protecting
Founded in 1888, The Ontario Historical Society is a non-profit corporation and registered charity; a non-government group bringing together people of all ages, all walks of life and all cultural backgrounds interested in preserving some aspect of Ontario’s history.
The OHS has a provincial mandate, but its headquarters is located at the historic John McKenzie House (built 1913) in Willowdale, Ontario. John McKenzie House, and its adjacent stables and milk-house are all designated under the Ontario Heritage Act.
The OHS is governed by an all-volunteer board of directors, and is supported by and supports its vast network of member individuals, organizations and institutions, including the OHS’s 350+ affiliated societies.

OHS mourns the loss of a heritage champion.

Eleanor Jane Beecroft
September 16, 1932 – October 11, 2021

Jane was a Life Member of the OHS and Founding President of The Community History Project. She will be greatly missed by many.

Very pleased to share Dr. Robin Nelson's excellent Keynote Address from the 133rd OHS AGM, held on Tuesday Oct 5:

"The Democratization of Culture: Reflecting on Similarities and Differences in Community Museums' Development in Ontario and Yukon"

The Department of Canadian Heritage has announced that it is now accepting applications for its Reopening Fund for Heritage Organizations. Apply now!

Just a quick reminder to all our members that this year's Annual General Meeting will once again be held later in the year. A final date and format will be provided to all OHS members shortly.
