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.
