The Ottawa Civil Liberties Association (OCLA) emerged in reaction to the espionage commission of 1946. Wilfrid Eggleston was elected as the OCLA's first president and the group’s founding members included such well-known figures as Senators Arthur Roebuck and Cairine Wilson. Unlike similar organizations in Winnipeg and Toronto, the Ottawa group did not exclude communists but instead attempted to bridge the ideological gap that had previously plagued the movement. The OCLA lasted a handful of years but the internal conflicts between communists and social democrats/liberals proved to be too difficult to overcome, and the group was soon disbanded.

According to Ross Lambertson: "The OCLA appeared to have been one of the last attempts to create a civil liberties organization which spanned the increasing ideological gulf between the far left and those further to the right. ... It was
a 'respectable' organization, composed for the most part of liberals and social democrats, the honourary president of which was Harry Southam, the publisher of the liberal Ottawa Citizen and at least one member, Edith Holtom, was active in the local CCJC committee. Shortly after it was created, the OCLA quickly sent off a resolution of protest to the federal government, as well as lobbying individual MPs to opposed to such departures from British practice. ... Wilfrid Eggleston, was a prominent freelance journalists who, ironically, had served at one time as the chief war-time censor for the government in Ottawa. A man who called himself a liberal in the mould of John Stuart Mill, Eggleston was also the Ottawa editor of Saturday Night. In the fall of 1946 he resigned as president, and was replaced by JP. Erichsen-Brown, an Ottawa later who served as counsel for Emma Woikin, the first of the accused spies to be tried in court. Erichsen-Brown came from a family with strong social democratic and civil libertarian tendencies, and was fundamentally opposed to the membership of communists in a civil liberties organization.'"
