The UFO Files digs deep into the government’s archives to unravel the true story of Canada’s fascinating connection to the UFO phenomenon. Weaving together eyewitness accounts and secret government files, including newly declassified documents, Palmiro Campagna relates some startling episodes in Canadian UFO history; ranging from the revelations made to Wilbert Smith, a Canadian Ministry of Transport engineer, and the unexplained case of Stefan Michalak, whose close encounter with a strange, burning hot craft left him physically scarred. It also explores the United States’ so-called "black" program, which may have originated with the Avrocar (also known as the Project Silver Bug), the United States Air Force flying saucer built in Canada.

The Toronto Star noted that The UFO Files provides "a detailed and convincing portrait presented with an astonishing array of archival evidence and photographs." While George Filer, New Jersey State director of the Mutual UFO Network, said this book "is well worth reading and helps unravel the true story of UFOs in Canada."

As Palmiro Campagna demonstrates, the truth is indeed out there.
