The collection contains records pertaining to the religious life of Joseph-Marie Couture, S.J. As the man credited with introducing aviation to Northern Ontario, a number of records pertaining to flight and his aircraft can be found in the collection: correspondence between Father Couture and the Provincial concerning his plane, flight-related budgets and expense lists, newspaper articles and books written during and after his life about his story of flight, and a number of photographs of Father Couture and various community members with his plane.

His long career at Longlac and Lake Nipigon, Ontario is demonstrated by a substantial amount of correspondence reporting to other Jesuits about his experience, as well as requesting supplies and detailing logistics. While the bulk of the correspondence is in letter format, the collection also comprises a number of telegraphs sent to Father Couture commemorating his silver Jubilee (indicating 25 years in the Society of Jesus). Additionally, the collection contains a small number of his personal belongings, including a mass book, Longlac paraphernalia like brochures, and several diplomas and certificates.

Many of the records pertain to the aftermath of Father Couture’s death: photographs of his tomb-unveiling ceremony, commemorative articles and scrapbooks produced by colleagues and friends, and telegraphs sent to his contemporaries in Longlac expressing condolences for his passing can all be found in the collection.
