Hovering lights in the sky. Pulsing lights. A humming noise.

Objects shaped like spheres, discs, triangles and boomerangs.

The witnesses include ordinary folk, airline crews, a particle physicist and an airport’s weather observer.

A survey released by Manitoba-based Ufology Research on Tuesday says there were 1,101 UFO sightings – an average of three a day – reported in Canada in 2017.

About eight per cent of those were deemed unexplainable.

“Many people continue to report unusual objects in the sky, and some of these objects do not have obvious explanations,” says the survey.

“Many witnesses are pilots, police and other individuals with reasonably good observing capabilities and good judgment.”

Quebec had the most sightings at 518. Nunavut had the fewest at two.

Montreal, Toronto, Vancouver and Edmonton topped the cities with the most UFO reports.

Ufology Research takes data from all known sources, including UFO organizations, government files, direct witness reports, media and some internet posts. Its analysis takes into account location, types of encounters, reliability of witnesses and strangeness of sightings.

As long as it's not MUFON.
