The Official Definition of an OSI

An operational stress injury (OSI) is any persistent psychological difficulty resulting from operational duties performed by a Canadian Forces member. The term OSI is used to describe a broad range of problems which usually result in impairment in functioning. OSIs include diagnosed medical conditions such as anxiety, depression and post traumatic stress disorder (PTSD) as well as a range of less severe conditions, but the term OSI is not intended to be used in a medical or legal context.
