Analysis of information sources in references of the Wikipedia article "Fred Rose (politician)" in English language version.
I am sure my colleague from CIJA is aware that the last case of citizenship revocation on grounds of treason was to a Jewish Canadian citizen named Fred Rose, who at that time was seen as breaching what is called the fundamental betrayal of core values of Canada. He was a Communist and was convicted of conspiracy to disclose secrets to the Soviets. He didn't actually do it; he was convicted of conspiracy to do it. He had his citizenship revoked. It was the Conservative government of Prime Minister John Diefenbaker that introduced what was known as the 'Fred Rose amendment,' in 1958 so that it would never happen again.
