Beginning in the 1950s, alleged sightings of unidentified flying objects in Canadian skies bred tension between the state and its citizens. While the public demanded to know more about the phenomenon, government officials appeared unconcerned and unresponsive. Suspicion of government deepened among certain sectors of Canadian society in the decades that followed, leading to demands for greater public transparency and a new kind of citizen activism.

In Search for the Unknown Matthew Hayes uncovers the history of the Canadian government’s investigations into reports of UFOs, revealing how these reports were handled, deflected, and defended from 1950 to the 1990s. During this period Canadians filed more than 5,000 reports of UFO sightings – many with striking descriptions and illustrations – with branches of government and law enforcement. Although the government conducted some exploratory studies, officials were unable to solve the mystery of UFOs or provide satisfactory answers about their alleged existence, and they soon declared the matter closed. Dissatisfied citizens responded by taking matters into their own hands, starting UFO clubs and civilian investigation groups, and accusing the government of a cover-up. A mutual mistrust developed between citizens who were suspicious of their government and officials who dismissed their fears and anxieties. This provided fertile ground for anti-authoritarian attitudes and the cultivation of conspiracy theories.

In an era of political division, and amid heightened awareness of states’ responsibilities for their citizens, Search for the Unknown reveals the challenges that governments face in responding to public anxieties and preserving trust in public institutions.

“Meticulously researched, Search for the Unknown is a much-needed title that fills a gap in the history of Canada’s UFO dealings. Although Hayes doesn’t take a position on the existence of these flying objects, he peppers his book with just enough of the fun stuff to give a predominantly academic work some entertainment value. Quirky pencil sketches of spacecraft by eyewitnesses and a few compelling reports that left even the government scratching its head are pleasantly juxtaposed with the more detailed bureaucratic record.” Literary Review of Canada

"In this sober and original book, Hayes reconstructs attempts by the Canadian government to investigate—or to limit consideration of—UFO reports across the span of the Cold War. Consistently intriguing and handled in clear prose style." Choice

“It is easy to ridicule conspiracy theorists but Hayes is careful to explain that [the appeal of these ideas] was in part due to the increasing lack of trust in the government in the 1960s, the call for greater transparency and the dismissive attitude of government departments. … This a very readable account of the response to UFOs in the shadow of the USA.” Magonia Review

“Although the subject of unidentified flying objects (UFOs) is very popular and has persisted since the 1940s — when the darned things were known as flying saucers — skeptics often note that few academic or scholarly studies on this topic have been produced. Search for the Unknown: Canada’s UFO Files and the Rise of Conspiracy Theory, based on the excellent doctoral dissertation by Canadian historian Matthew Hayes at Trent University, challenges that assertion.” Winnipeg Free Press
