[2] In an interview she stated that she was until 1948 a prisoner in a "Russian concentration camp";[4] she also reported being raped by the Soviet soldiers who invaded Germany at the end of the Second World War.
She was married for a short period to a demobilized American soldier and baseball player named Michael Munsinger, but divorced him in 1954 after she was unable to return to the US with him.
Once her term was completed, she found jobs as a waitress, a call girl, and a hostess at the "Chez Paree" nightclub; she also aspired to be a model.
[2][3] Munsinger became involved in relationships with a number of high-ranking Canadian government officials, most notably cabinet ministers George Hees and Pierre Sévigny.
She later commented negatively about Hees, suggesting he was "an ex-football star and that's it" who was "too sure of himself as a man"; Sévigny, in contrast, she pitied, saying that newspaper reports about him and his family were "nothing but lies" and that "he was the most innocent person in the whole affair".
[6] The Royal Canadian Mounted Police (RCMP), after learning that the Central Intelligence Agency considered Munsinger to be a "definite security risk", interrogated her in 1960 and conducted surveillance on her telephone conversations.
[6] The affair became public in March 1966 when Minister of Justice Lucien Cardin mentioned Munsinger's name during a debate in Parliament, in response to comments from the Conservatives about security problems in the Liberal government of Lester B.
[7] The Liberals had been made aware of the affair two years earlier during a review of security cases involving senior government officials; Pearson had opted to not publicize it, and had instructed his cabinet ministers not to discuss it.
Despite being told by Pearson not to say anything further, Cardin disclosed during a press conference that "Olga" Munsinger had been involved with Conservative politicians; he compared the incident to the affair between John Profumo and Christine Keeler in the UK.
A Canadian reporter with the Toronto Star, Robert Reguly, found her alive and well in Munich, West Germany, after locating her phone number in a local phonebook.
[4][9] After the story broke, the police were sent by the German government to guard Munsinger's apartment and prevent unauthorized access, as a crowd of reporters camped outside for several days.
