Unidentified Flying Objects (UFOs) apparently buzzed the National Capital Region (NCR) the evening of 4 March 1969.

UFOs were spotted directly above the Parliament Buildings on Parliament Hill and Rideau Hall. Yurko Bondarchuk in UFO0: S:sightings, Landings and Abductions (1979) quoted the testimony of an RCMP constable stationed near the Privy Council entrance the evening of March 4:

At 7:45 p.m., an object was seen from Parliament Hill, going through the sky at a terrific rate of speed, heading from south to north. This object stopped and appeared to hover in the sky over Hull. It gradually moved in a northwest direction and at 9:34 p.m. disappeared from view. It appeared to be round in shape and much smaller than the moon in size.

The object was seen by six other RCMP officers at various locations on Parliament Hill.

Later that evening an RCMP constable patrolling the part of Sussex Drive between Rideau Hall, the Governor General's Residence, and 24 Sussex Drive, the Prime Minister's Residence, observed flashing red lights:

At approximately 10:00 p.m. , while on foot patrol from the police lodge at Government House to the prime minister's residence, 1 noticed two rather bright flashing red lights in the sky. At first glance, I assumed they were aircraft but could hear no sounds of engines. One of these lights proceeded east and was lost from view within a minute or less, while the other one travelled in a westerly direction. These lights were first seen directly overhead at a point slightly inside the gates to Government House and were very bright red. No definite shape could be distinguished nor was there any type of trail visible behind these lights.

Three months later, on 5 June, at 10:12 p.m., three RCMP constables and three tourists on Parliament Hill were surprised to see a luminous craft hovering over the Ottawa River behind the Parliament Buildings. Bondarchuk noted, "They watched as the vessel emitted a dazzling array of lights, changing from red to green to red to white." At 10:10 p.m., "all the lights on Parliament Hill - East, West and Centre Blocks - went out . . . Ontario Hydro was notified, but . . . the cause could not be ascertained at the time." Then the UFO moved eastward "with an up and down ping-pong-ball-like trajectory," finally settling above eastern Hull and Pointe-Gatineau across the river. It proceeded west and then disappeared from sight behind high buildings.

Bondarchuk commented on the lack of official interest in the incidents which he found disturbing.

"It is equally disturbing that neither the sighting nor the blackout received noticeable press coverage. A check of subsequent editions of the Ottawa Journal and the Ottawa City:zen failed to reveal any reference to either event. Whether this omission was intentional or accidental does not alter the fact that while two potentially explosive events were taking place, the public was left virtually in the dark."
