CFB Falconbridge — Canadian Nuclear Base UAP Intrusion

In November 1975, Canadian Forces Base Falconbridge near Sudbury, Ontario, experienced UAP intrusions that occurred simultaneously with the documented wave of incursions over US nuclear weapons storage facilities (Loring AFB, Wurtsmith AFB, Malmstrom AFB, Minot AFB, and F.E. Warren AFB). NORAD radar confirmed anomalous contacts over CFB Falconbridge. The Canadian base was a NORAD radar installation and was part of the North American Air Defense network. Canadian Forces security personnel observed the objects. The incidents were documented in Strategic Air Command classified messages that referenced both the US and Canadian bases as part of the same operational concern. These SAC messages were released under FOIA requests and are among the declassified documents confirming that US military authorities recognized the simultaneous nature of the incidents across North American nuclear and defense infrastructure. The CFB Falconbridge incidents were also referenced in USAF documents describing the broader November 1975 wave as 'alarming' due to the coordinated geographic pattern. Canada's National Archives holds the Canadian Forces records relating to the Falconbridge incidents.
