Dear General Foulkes, I enclose a copy of the telegram which we sent to Sir Edward Travis concerning the transfer of the wireless station at Oshawa. I als© enclose the reply which we have now received. Perhaps you would let me know whether you would prefer to send representatives to the United Kingdom or whether we should ask Sir Edward Travis to send representatives here. It seems to me that it would probably be more useful to follow the latter suggestion as detailed questions concerning the transfer seem more likely to occur at this end. I. also enclose a copy of a memorandum which Mr. Heeney sent me concerning his discussion on the question of Hydra with Mr. Ilsley. You will recall that you asked me to send this to you at the last meeing of the Chiefs of Staff. A / y. Yours very truly, /yyyL Under-Secretary of S t a t e for External A f f a i r s .

I am now able to inform you, however, that the Canadian authorities suggest the transfer of Hydra to Canadian Goverraasnt ownership. I understand that '''"'• \ ^.m property and equipment as it stands will he handed ™ over at no cost. The station will be operated by the Canadian Army using the ©xlsting civilian employees who v/ould bo gradually replaced by Army i personnel. It is understood that the station would bo used for Sigint traffic betv/een London, Ottav/a i ! and Washington. For the time being, the present transmitters only would bo used but the Army may supplement or replace them at a later date depending on the volume of traffio. At an early stage it was suggested that tho Foreign Office might wish to send through Hydra their own traffic froju London and Washington. This would be quite acceptable if they still desire to do so and I have under consideration similar arrangements for communications between External Affairs and Canada House. I presume that the volume and types of traffic and any other questions of common interest to London, Washington and Ottawa would be the subject of consultation as required.

MEMORANDUM FOR MR. PEARSON1 For attention Mr. Crean After my conversation with Crean yesterday morning, I had an opportunity of mentioning to Mr. Ilsley the authority given by Mr. Abbott for the operation by the Canadian Army of the transmitter station at Oshawa. I told him that prior to Mr. Robertson's departure for London he and I had discussed the matter with Mr. St. Laurent and Mr. Abbott and that it was then agreed that it would be reasonable for the government to take over this function as part of the cooperative U.K.-U.S.-Canada programme in the field of interception. I also told him of the high degree of secrecy attached to this operation, knowledge of which must therefore be confined to as few persons as possible. Mr. Ilsley was satisfied to have the Oshawa station taken over in the way proposed, on the understanding that there was no capital cost involved and that the funds .were available in National Defence (Army) votes. It will therefore be in order now to inform the U.K. Government of the Canadian Government's willingness to undertake this responsibility. I should be grateful if I could have, for my file, a copy of the telegram which goes forward to the United Kingdom. I understand that the other proposals set forth in the draft memorandum to the Defence Committee, dated November 8th, will be brought forward later on. "A. D. P. H." A. D. P.
