In 1967 the festival was no longer a non-profit organization. It had undergone many changes under the direction of Estelle Klein such as breaking the acts up into multiple stage areas where concerts occurred simultaneously and the workshop format, which was to be adopted by other folk festivals within North America as well as a broader range of performers. The festival took place from August 11-13 at Innis Lake, Ontario. Performances included Leonard Cohen, John Cunningham, Rev. Gary Davis, Roger Deveer Renwick, The Dildines, Bonnie Dobson, Michael Edmonds, Dick Flohil, Louise Forestier, Canadian folklorist, Edith Fowke, Buddy Guy Blues Band, Ritchie Havens, Kensington Market, Louis Killen, Penny Lang, Lilly Brothers & Herb Hooven, Estelle Klein, Gordon Lowe, Allan MacLeod, Alan MacRae, Owen McBride, Murray McLaughlan, Joni Mitchell, Alanis Obomsawin, O.D.
