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)
Greenwood Lake White Pine (1979)

Records relate to research carried out by Viitala and colleagues at Lakehead University as part of the Acidic Precipitation In Ontario Study. Field research was done at Hawkeye Lake northwest of Thunder Bay, and at Pukaskwa National Park. The records include data, photographs, reports and research papers. Some records also relate specifically to the International Symposium on Acidic Precipitation held at Muskoka on September 15-20, 1985.

Records date primarily 1980-1988, with some additional documents from 2018 and 2022.
