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.

Voices of the Grain Trade oral history project:
"Our volunteer interview teams in Thunder Bay and Winnipeg did their best to collect voices reflecting all major facets of Canada's international grain trade. As a result, you will find interviews with farmers, researchers, plant breeders, company owners, and railway employees blended in with the stories of grain handlers, inspectors, lake shippers, regulators, builders, marketers, and many more. Our voices are spread from Quebec City to Victoria, with the highest concentrations being from Thunder Bay and Winnipeg."

The records include audio recordings of oral history interviews, accompanied by transcripts and releases.

The Northwestern Ontario Regional Day Care Committee / Child Care Committee operated from the 1970s to the 1990s.

The Committee was engaged in advocacy work, as well as supporting the work of child care centres and professionals.

Records of the Committee include minutes, membership lists, newsletters, correspondence, and other records associated with the advocacy activities of the organisation. Includes correspondence with governments and partner organizations.
