Introduction
In CADORS, “UFO” is best read as an aviation-safety label, not as a verdict about alien craft. CADORS is Transport Canada’s Civil Aviation Daily Occurrence Reporting System: a public record of aviation occurrences used to alert the department, share basic safety information and help spot hazards. When an unusual light or object is logged there, the key question is usually practical: did it pose a risk to aircraft, airspace management or public safety? Transport Canada has explicitly said that “UFO” in CADORS can cover drones, balloons, meteors, weather phenomena and birds, and should not be interpreted as extraterrestrial origin.

That distinction matters for Nunavut because the territory’s most visible UFO-linked case, the 24 November 2018 Baffin Island pilot sighting, entered public attention through a CADORS report. The record made the event official in an aviation sense, but it did not prove that the object was exotic. It showed that professional pilots saw something unidentified, that the sighting was logged through a safety system, and that the available details were limited.

What CADORS records are actually for
CADORS was not created as a UFO investigation programme. Transport Canada says it was launched in 1985 to provide timely information about civil aviation occurrences and to capture information that air traffic services certificate holders are required to report under Canadian Aviation Regulations section 807.01. In ordinary use, CADORS covers the full range of aviation events: aircraft incidents, airport hazards, wildlife strikes, operational disruptions, system deficiencies and other occurrences that may matter to safety. [Transport Canada]tc.canada.caTransport Canada The Civil Aviation Daily Occurrence Reporting System (CADORSTransport Canada The Civil Aviation Daily Occurrence Reporting System (CADORS
The system is useful because it creates a fast public-facing trail of events that aviation stakeholders may need to know about. Transport Canada’s own aviation safety explanation says CADORS helps ensure that civil aviation occurrences are recorded, stakeholders are notified, hazards are identified, and events are evaluated for factors that may need mitigation. It also notes that Transport Canada Civil Aviation received an average of about 16,750 aviation incident and accident reports annually over the five years before that 2021 article, roughly 45 reports per day. [Transport Canada]tc.canada.caTransport Canada The Civil Aviation Daily Occurrence Reporting System (CADORSTransport Canada The Civil Aviation Daily Occurrence Reporting System (CADORS
This is why CADORS records should be read differently from a finished accident-investigation report. Transport Canada describes CADORS as providing initial information, and its online services page warns that reports contain preliminary, unsubstantiated information that is subject to change. [Transport Canada]tc.canada.caTransport Canada Civil aviation online services and applicationsTransport Canada Civil aviation online services and applications For UFO-related entries, that warning is especially important. A pilot or controller may honestly report an unusual light, but the first record may lack the distance, altitude, speed, duration, direction, radar confirmation, photographs or later analysis needed to identify it.
In practical terms, CADORS is closer to an early warning and indexing system than to a courtroom judgement. It can show that an unusual event was reported through Canadian aviation channels. It cannot, by itself, show what the object was.
Why “UFO” is a safety label
The word “UFO” carries a heavy cultural meaning, but in CADORS it is often a deliberately broad bucket. Transport Canada’s 2023 briefing material on high-altitude object incidents says the term can describe many things, including remotely piloted aircraft systems, balloons, meteors, weather phenomena and birds. The same briefing says CADORS information is used for early identification of potential hazards and system deficiencies and should be treated as preliminary, unsubstantiated and subject to change. [Transport Canada]tc.canada.caTransport Canada4. High Altitude Object IncidentsTransport Canada4. High Altitude Object Incidents
That makes the label both useful and easy to misunderstand. It is useful because air traffic services need a way to record an object or light that is not immediately identifiable but might affect flight safety. A crew does not need to know whether a light is a meteor, drone, balloon or unknown aircraft before reporting it. The safety system benefits from knowing that something was observed, where it was seen, who saw it, and whether it affected operations.
It is easy to misunderstand because the public often reads “UFO” as a claim about extraordinary origin. CADORS uses the term much more modestly. In the Sky Canada Project report, the Office of the Chief Science Advisor described Transport Canada as maintaining CADORS for incidents affecting aviation safety, including unidentified aerial phenomena sightings. It also explained that Transport Canada analysts assign such reports to event categories depending on available details, including “Weather Balloon, Meteor, Rocket, UFO and Intelligence Sighting”, “Laser Interference” or “Other Operational Incidences”. [Science.gc.ca]science.gc.caManagement of Public Reporting of Unidentified Aerial Phenomena in CanadaManagement of Public Reporting of Unidentified Aerial Phenomena in Canada
For a Nunavut reader, the safest interpretation is therefore: CADORS confirms that an aviation-related observation was logged; it does not confirm the nature of the object. The word “unidentified” means the record does not identify it, not that ordinary explanations have been eliminated.
The reporting chain behind a Nunavut sighting
The Canadian reporting chain is important because it explains why a short pilot observation can become a government record. The Sky Canada Project says pilots typically report UAP sightings to the nearest air traffic control tower, flight service station or other air traffic unit. Those units file an Aviation Occurrence Report with NAV CANADA, which is then sent to Transport Canada’s CADORS team for assessment and processing. NAV CANADA provides about 80 per cent of the aviation occurrence information used in each CADORS record, while other sources can include the Transportation Safety Board, RCMP, aircraft operators and other agencies. [Science.gc.ca]science.gc.caManagement of Public Reporting of Unidentified Aerial Phenomena in CanadaManagement of Public Reporting of Unidentified Aerial Phenomena in Canada
This matters in Nunavut because aviation is not a minor backdrop. Across the North, aircraft are central to movement, work, emergency response and community connection, and many routes cross remote terrain where ground witnesses, radar context and easy follow-up may be limited. A strange light reported by a flight crew may therefore have a better chance of entering official records than a casual ground sighting, even if the crew saw only a brief or ambiguous object.
The 2018 Baffin Island case illustrates the process. Nunatsiaq News reported that Nolinor Aviation pilots, flying a Boeing 737-200 from Iqaluit to the Mary River mine, reported an unidentified object at about 8:30 p.m. local time on 24 November 2018. The CADORS report offered several broad possibilities: weather balloon, meteor, rocket or another unidentified flying object. It used the category “CIRVIS/UFO”, and the report said NORAD was advised. [Nunatsiaq News]nunatsiaq.comNews Pilots report UFO sighting over Nunavut’s northern Baffin IslandNunatsiaq NewsPilots report UFO sighting over Nunavut’s northern Baffin Island…
That looks dramatic at first glance, but the safety meaning is narrower. The same report said the flight experienced “no impact to operations”, and Transport Canada told Nunatsiaq News that the information should be treated as preliminary, unsubstantiated and subject to change. A Nolinor vice-president later said the pilot described a shining light changing from red to green to white and suggested it was “probably something natural”. [Nunatsiaq News]nunatsiaq.comNews Pilots report UFO sighting over Nunavut’s northern Baffin IslandNunatsiaq NewsPilots report UFO sighting over Nunavut’s northern Baffin Island…
The official record therefore does two things at once. It raises the evidential value above a rumour, because trained pilots reported the observation through aviation channels. It also limits the claim, because the record remained brief, preliminary and consistent with several ordinary sky phenomena.
CIRVIS, NORAD and the danger of over-reading official routing
The Baffin Island record attracted attention partly because of the phrase “CIRVIS/UFO” and because NORAD was reportedly advised. These details are meaningful, but they should not be inflated.
CIRVIS stands for Communications Instructions for Reporting Vital Intelligence Sightings. In modern public discussion, it tends to appear when pilots or controllers report unusual or potentially significant aerial sightings. Sky Canada explains that further follow-up on CADORS UAP reports may be undertaken by several organisations, including Transport Canada, NAV CANADA, the Transportation Safety Board of Canada and NORAD. [Science.gc.ca]science.gc.caManagement of Public Reporting of Unidentified Aerial Phenomena in CanadaManagement of Public Reporting of Unidentified Aerial Phenomena in Canada This means that a report can move through security-aware channels when the nature of an aerial object is unclear.
That does not mean NORAD confirmed a threat or that the sighting was treated as evidence of non-human technology. It means the observation entered a reporting structure designed to handle uncertain aerial events responsibly. In Canada’s airspace, unknown objects can matter for mundane but serious reasons: collision risk, misidentified traffic, balloons, drones, rockets, space debris, military activity, sensor gaps or pilot distraction.
Transport Canada’s own high-altitude object briefing after the 2023 balloon incidents reinforces this point. It discusses UFO wording in CADORS alongside balloons, drones and aviation safety action such as NOTAMs, not as a paranormal classification. It also states that balloons are aircraft under the Aeronautics Act and that large unmanned balloon operations in Canada require specific authorisation. [Transport Canada]tc.canada.caTransport Canada4. High Altitude Object IncidentsTransport Canada4. High Altitude Object Incidents
For Nunavut UFO history, this is one of the most important interpretive rules: official routing increases the seriousness of the record, but not necessarily the strangeness of the object.
How CADORS changes the value of the 2018 Baffin Island case
Without CADORS, the 2018 Baffin Island sighting would be a local news story based mainly on witness recollection. With CADORS, it becomes a traceable aviation occurrence: a dated report by professional pilots on a named route, involving a known aircraft type, a rough location near the Mary River mine and an official safety category. [Nunatsiaq News]nunatsiaq.comNews Pilots report UFO sighting over Nunavut’s northern Baffin IslandNunatsiaq NewsPilots report UFO sighting over Nunavut’s northern Baffin Island…
That makes it valuable within Nunavut’s UFO record for three reasons.
First, it gives the case a firmer public paper trail than many ordinary UFO anecdotes. The sighting was not simply posted online; it was logged in a Canadian aviation reporting system.
Second, it shows how little an official record may still contain. The public account did not provide enough detail to test the main explanations fully. The report mentioned broad possibilities but did not resolve them. A light that changes colour could be affected by atmospheric conditions, viewing angle, aircraft movement, distance, cloud, ice crystals or the observer’s changing line of sight, but a short report cannot sort those possibilities by itself.
Third, it demonstrates why unresolved does not mean extraordinary. The Baffin Island case remained unidentified in the limited public record, but the available information leaned towards a light-only sighting with no operational impact and a company representative’s natural-explanation suggestion. [Nunatsiaq News]nunatsiaq.comNews Pilots report UFO sighting over Nunavut’s northern Baffin IslandNunatsiaq NewsPilots report UFO sighting over Nunavut’s northern Baffin Island…
This is a useful corrective to two common mistakes. Sceptics should not dismiss the report as meaningless, because aviation professionals considered it worth logging. Enthusiasts should not treat the CADORS label as confirmation of alien craft, because Transport Canada explicitly warns against that reading of “UFO” in CADORS.

What CADORS can and cannot tell readers
CADORS is strongest when used to answer basic aviation-record questions: was an event reported, when did it occur, what aircraft or airspace was involved, what immediate safety effect was noted, and which agencies or systems were notified? It is weaker when used to answer the mystery question: what exactly was seen?
A careful reader should separate the record into layers:
- The report layer: a witness or aviation unit reported something unusual.
- The safety layer: the event was considered relevant enough to log, classify or pass along.
- The investigation layer: further follow-up may or may not have happened.
- The explanation layer: the object may remain unidentified in the public record even if ordinary explanations are plausible.
Sky Canada’s 2025 report makes this distinction clearer at the national level. It found that Canada’s UAP reporting landscape is fragmented and that most organisations do not investigate sightings unless they intersect with mandates such as national security or transportation safety. It also noted that UAP sightings are rare within CADORS: CTVNews.ca identified only 17 pilot-reported 2023 events that could be considered UAPs, about 0.08 per cent of pilot-reported incidences in CADORS. [Science.gc.ca]science.gc.caManagement of Public Reporting of Unidentified Aerial Phenomena in CanadaManagement of Public Reporting of Unidentified Aerial Phenomena in Canada
That rarity cuts both ways. It means CADORS UAP cases are notable when they appear, especially in a sparsely reported territory such as Nunavut. But it also means Transport Canada is not running a dedicated explanatory programme for each unexplained light. Sky Canada observed that when incidents do not raise serious safety concerns, Canadian authorities do not investigate further.

Why this matters for Nunavut’s UFO history
Nunavut’s UFO history is shaped less by mass waves of public sightings than by the interaction of remote geography, aviation dependence, sparse records and official reporting systems. CADORS helps explain why a single pilot report can stand out. In a territory with few publicly documented UFO cases, an aviation record gives researchers a firmer starting point than folklore, rumour or unsourced social media.
At the same time, CADORS also prevents overstatement. The system’s purpose is safety governance, not mystery-solving. It tells readers that Canadian institutions have a way to log unusual aerial observations when they intersect with aviation, but it also shows the limits of those records: preliminary data, broad categories, minimal descriptions and uneven follow-up.
That is why the Baffin Island report matters more as an example of Canadian aviation reporting than as a sensational UFO claim. It shows a professional crew reporting an unusual light; Transport Canada recording it under a broad category; NORAD being advised; no operational impact being reported; and later public commentary pointing towards a possible natural explanation. [Nunatsiaq News]nunatsiaq.comNews Pilots report UFO sighting over Nunavut’s northern Baffin IslandNunatsiaq NewsPilots report UFO sighting over Nunavut’s northern Baffin Island…
For a balanced Nunavut page, the headline lesson is simple: CADORS makes a UFO report official enough to take seriously, but not specific enough to treat as proof. The right question is not “Did CADORS confirm a UFO?” but “What safety-relevant observation was recorded, what information is missing, and what ordinary explanations remain plausible?”
How to read Nunavut aviation reports
A Nunavut CADORS-related UFO entry should be read with a practical checklist in mind. The most useful details are not the word “UFO” itself, but the surrounding information: aircraft type, route, location, time, altitude if available, whether air traffic control saw anything, whether radar or other aircraft corroborated the sighting, whether the flight changed course, and whether agencies issued warnings or follow-up notices.
The absence of those details does not make a witness unreliable. It simply limits what can be concluded. In northern aviation, a brief light in darkness can be important enough to report and still too poorly constrained to identify. That is exactly the space CADORS occupies: it preserves the occurrence for safety awareness, but the public record may remain too thin for a firm explanation.
The most responsible reading of CADORS UFO reports in Nunavut is therefore neither dismissive nor credulous. Treat them as aviation-safety signals first, UFO-history evidence second, and extraterrestrial claims not at all unless independent evidence actually supports that leap.
