An excellent report (pdf) summarizing 25 years of Canadian UFO reports. Ufology Research, formerly UFOROM (Ufology Research of Manitoba), has been collecting and reviewing Canadian reports since 1989, publishing the results as the annual Canadian UFO Survey.
As explained by the authors “…When the 2013 edition was published in 2014, it marked 25 years of the annual analyses of UFO report data. It seemed reasonable, then, to group all 25 years of data together and examine the data for trends and changes with time over a quarter of a century. When the final tally was produced, there were almost 15,000 UFO reports received as data since 1989. Coincidentally, this almost exactly matches the total number of UFO reports collected and analysed by the United States Air Force Project Blue Book during its official run of less than 20 years from 1952 to 1970. The Ufology Research study is titled “UFOs Over Canada: 25 Years of UFO Reports.” It is available from the Canadian UFO Survey web page here. In addition to the text document, the entire 25-year report database is also viewable.”
