The documents outline how the government investigated UFOs—a process that most likely lasted for years afterwards—and breaks down six cases that are “of interest” to the government in detail. The investigations include a man burned by a UFO in Manitoba, some incredibly weird radar sightings by the Department of Defence, an RCMP officer in Nova Scotia who watched a UFO dive below the water and disappear, and a crop circle found in Alberta that was the first investigated by a government.

A collection of documents from 1967 found in the national archives give us a hint into just how seriously the government used to take UFO sightings.

"What we do have in here is rather interesting reports from qualified personnel and qualified sources and investigated by qualified investigators and still there is no explanation," Rutkowski told VICE. "What that tells me is that the UFO phenomena was taking quite seriously by them indeed."

The documents were found in the national archive by Chris Rutkowski—a man that could probably be best described as Canada’s Fox Mulder—and recently posted to his Ufology blog. Rutowski routinely goes through Canada’s national archives looking for things like this and described the find as “a gem.”

While the government has some of tUFO research readily available online in a database it is still relatively unknown—especially among the general public—how they actually investigated cases and what the bureaucracy was like. This, Rutkowski says, might be “our best snapshot” into this process.

"This is certainly an interesting snapshot because it does show what was happening before and how it was going to move forward and I think it set the stage for how the Canadian military and government were looking at UFOs from that point onward,” said Rutkowski.

The 27 page set of documents—which Rutkowski was kind enough to direct VICE towards—was prepared by Wing Commander Douglas Robertson (a Canadian Forces officer well-known in the UFO community) for someone we do not know in November of 1967. Rutkowski speculates it could’ve been for a newly-appointed Minister of Defence as “the infamous Paul Hellyer [one of the world’s highest ranking alien believers] had left the position a few months earlier.” At the time, as Robertson writes, the National Department of Defence was the body in charge of investigating UFO reports.

The briefing breaks down the seven military categories of UFOs which include hoaxes, mass hysteria, misinterpretations of natural events, advanced military technology, and psychological conditions. However, the seventh and final category is “unusual sightings which the viewer is unable to identify or explain, namely, UFOs.” Hell yeah.
