The Ministry of Natural Resources began developing master plans for parks in the 1970s. The plan for Sleeping Giant Provincial Park (at that time Sibley Provincial Park) didn’t rely on any public consultation, and was not well received.

As more Park Plans were rolled out, the MNR engaged in more consultation. Responses to plans as well as draft and final Plans are included in these records.

Park Plans include those for:
Sleeping Giant Provincial Park (1972)
Northern Lights Lake Area Plan (1972)
Ouimet Canyon (1975)
Neys (1977) (no files)
Rushing River (1986)
La Verendrye (1985-1986)
Slate Islands (1985-1988)
Turtle River/White Otter (1990-1992)
Brightsand (1990-1993)
Lands for Life (1998)
Kakabeka Falls (2000-2001)
Black Sturgeon River (2002-2003) (no files)
Lake Nipigon Area Plan (2002-2003)

As well as other records related to:
Stanley Bur Oak park proposal (1988-1990)
Pukaskwa National Park Provisional Master Plan (1972-1995)
Graham Area Land Use Plan (1972)
Algonquin Park (1973)

The Coalition for Wilderness, initially proposed by Addison, represented five groups in speaking for wilderness parks in Ontario: Algonquin Wildlands League, Canadian Nature Federation, Federation of Ontario Naturalists, National and Provincial Parks Association of Canada, and Sierra Club Ontario Chapter.
