Chaput's increasingly active involvement in public affairs did not fail to grab the attention of his employer, the federal government in Ottawa. In the House of Commons of the Parliament of Canada, Douglas Fisher, NDP Member of Parliament for Port Arthur in Ontario, asked Minister of National Defense Douglas Harkness about a certain doctor Chaput. Harkness was forced to admit that the Marcel Chaput, public speaker promoting the independence of Quebec was the same Marcel Chaput employed by his department. The Parliament of Canada took interest in his case again after some French-speaking MPs received invitations to attend a public meeting of the RIN announced for May 30, 1961 at the École normale de Hull. The day of the event, Chaput was called in the office of doctor Keyston, vice-president of the Defence Research Board, and was threatened with firing if he gave his talk. Knowing that Keyston did not have the powers to fire him, he decided the give his talk as planned.
