Public opinion in Canada, however,\nincreasingly supports the construction of an all -Canadian - Seaway,\npartly as a symbol of developing Canadian nationalism.\nIV. Summary Statement of Principal Points Previously Advanced\nin Testimony before Congressional Committees by various\nRepresentatives of the Irior Administration\n12. Labrador Iron Ore\na. The St. Lawrence Seaway, in addition to its\nundoubted general contribution to our transportation sys-\ntem, is essential if we are to put our steel production\n--\nwhich is to say our entire mobilization effort -- on\na\nsolid and secure foundation. Without the Seaway, we shall\nbecome steadily more vulnerable in steel production, the\nmost strategic of all strategic industries.\nb. The Mesabi deposits of high grade iron ore are\n(no\nbeing gradually depleted. There are two alternate sources\nof supply: the use of low-grade domestic deposits (taco-\nD\nnite) and the importation of foreign high-grade ores.\nThe importation and development of foreign ore must be\naccelerated because the exploitation of our taconite will\nrequire extensive and costly research and development and\nthe construction of facilities through a slow process\nover a period of years. There are two principal sources\nof foreign high-grade iron ore in this hemisphere, South\nAmerica and Labrador. The high-grade ores of Labrador,\nthe only rapidly expansible supply on this continent, are\nof particular importance to national security. In time\nof war, if the Seaway were completed, ore from Labrador\ncould move to the Great Lakes by a sheltered route during\npart of the year, in contrast with the hazardous open-\nocean routes around the seaboard and from South America.\nC. Freedom from submarine attack does not, of course,\nmean full security. The risk of interruption of the new\nSeaway by enemy sabotage must be faced. The danger of\nsabotage, however, is already of critical importance at\nthe locks of Sault Ste. Marie, through which our Lake\nSuperior ores are brought in such vast quantity. Until\nthe Seaway is built, almost the whole of our iron ore\nsupply is subject to interruption by a single act of\nsabotage there.\n13. Security and Economy of Overseas Shipping. The Sea- -\nway will facilitate the transportation of munitions to oversea\nbases. For example, it would shorten for part of the year by\nNSC 150\n- 4 -\nCONFIDENTIAL"
