The collection consists of architectural plans and drawings for construction projects (primarily grain elevators) in Ontario and Manitoba.

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.

A media kit, produced by Grand Council Treaty Number 9. Titled "Reed's Greed," the materials here relate to opposition to Reed Paper (Canada) Ltd., the company responsible for mercury pollution in the English & Wabigoon River system, affecting the people of Grassy Narrows First Nation/Asubpeeschoseewagong Netum Anishinabek.

Most material dates from 1976. At this time, Reed was planning an expansion of its forest products operations and requesting increased timber rights from the Ontario government. This is also a time after the mercury pollution had been identified by researchers and made known to governments, but long before any settlements were reached.

Documents include media releases, clippings, information sheets, and posters for protest events in Winnipeg.

Most materials are in English; some in an Indigenous language written in syllabics.
