Ehil© these studio© differ aoriewhat in approach, it io eloar that th© tf.Q. intelligonco agencies are cosamoncins the production of a very similar study and expect, upon its completion, to exchange it with any available Crnodian study. 4 It is also apparent froa the advice rocoivod that the t?.C. paper is beiig designed to fit into other studies whose purpose is to determine ultimately txss the strateglo intentions and capabilities of tho Soviet Chios on a lons-tero basis, fhe tJ*K. studies, though different in approach, havo the sane object in view. 5 .7itb these coneideroticne in aiad, we fool that the initiation and production of a study of this kind as it pertains to Canada is of ©strode importance. 6 W© also consider that since this paper hac ae its objective integration with one of u.fc« origin, the approval of higher authority should be sought at the outset, since such approval will bo required oa the completion of the paper, ue also consider that the complexity and nature of the initial studios neceecery to approach the problem aro such that their authoritative coapllotien is beyond th© scope of our technical knowledge and experience, end therefore approval of hieher authority ©ill have to ba sought in ordej? that the other government -Departments and egencies can bring tbeir resources to bear on t^e study. 7 In this regard we have, ia our discussions, been forced to the conclusion that nose of the present Interdepartmental comittees of th© government ®*® doelgaed to meet the preliminary requirements of this study. B Consequently we have concluded that, in ordor to fulfil thee© preliminary requirements, it will be nooeesory for on approach to be Eode to the Chiefs of Gtaff Ccsssitte® whicbt in turn would have to seek authority top the setting-up of an inter-departmental working group composed of scesbers of interested departments, fhis \torkins group would then fulfil tho necessary reiuireaente and pass the results to th© 3TCC. fh* 3TC would, in turn, direct the JIS to epp.ly tho necessary ailitary factors in order to produce the requisite paper for planning purposes. «*•»••/2. 000449 �Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'information f .sS- (h^] £? •2- TOP S^CRhfl 9 *te have attached a t Appendix * *, ao directed by tho ChcirDon, JIC, a draft of a reoosaendatica to the Chi fs of Staff Casual t t e e along these l i n e s . r:e nave aleo ©ttaoheaT^s directed, a concept of an approach t o tho problem includ lag a eta tomtit of sosa* of the requirements which, ia our opinion, iaifiht %oll have to be fulfilled by tho working croup Bugsoatod above. 000450 i �f Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'information t .r n A ^F TOP r. era? ? ™ COFJT no. .
