The 1990 Montreal UFO Incident, also known as the Place Bonaventure Incident, occurred on November 7, 1990, when witnesses at the Hotel Bonaventure in Montreal, Quebec, observed a large, silent, and brightly lit object hovering over the building's rooftop pool. The phenomenon began at 7:20 p.m. and lasted until 10:10 p.m., when it was obscured by clouds, with witnesses describing a metallic object approximately 540 metres wide emitting green, amber, and yellow lights in a circular pattern.
The sighting was extensively documented by hundreds of witnesses, including hotel staff, security guards, and police officers, who ruled out common explanations like construction spotlights by having them turned off while the object remained visible. The Royal Canadian Mounted Police (RCMP), local military, and NASA investigators were called to the scene, and subsequent analysis by UFO researcher Bernard Guénette and former NASA scientist Dr. Richard Haines concluded that the evidence for a "highly unusual, hovering, silent large object" was indisputable, though its origin remains unexplained.
