Montréal: the object over Place Bonaventure
For about three hours on the evening of 7 November 1990 some forty people, including Montréal police officers and La Presse journalists, watched a motionless object with three yellowish lights and a single beam above the rooftop pool of the Hilton Bonaventure. Police called the RCMP, which assigned an officer; a La Presse photographer took two exposures. National Defence said it had no operations, and Dorval airport saw nothing on radar.

Plausibility weighs how well an account fits where secrecy hides the documents by design, so missing records never count against it. Strength measures what is documented. Assessed 2026-10-23.
