 The next step was to broach the matter with the Canadians. The Lord President, Sir John Anderson, as the minister responsible for Tube Alloys, wrote to the British High Commissioner to Canada, Malcolm MacDonald, who had been involved in Tube Alloys negotiations with Canada regarding the Eldorado's uranium mine at Port Radium and its refinery in Port Hope, Ontario. On 19 February 1942, MacDonald, Thomson and Wallace Akers, the Director of Tube Alloys, met with C. J. Mackenzie, the president of the NRC, who enthusiastically supported the proposal. The following day he took them to see C. D. Howe, the Minister of Munitions and Supply.
