For analysis, total Seaway cargo tonnage was divided into the following major commodity components: iron ore, grains, coal and coke, petroleum and petroleum products, general cargo, and minor bulk commodities. Factors determining the movement of each of these traffic components were studied and high and low estimates of future cargo tonnage were projected. Based on these estimates, the projection of total cargo movements through the Seaway is presented for 1965, 1970, 1975, 1980 and 2000. Iron ore and grains are expected to continue to be the largest components of cargo movements, each comprising about one-third of the total. The estimates were found, in general, not to be easily influenced by moderate changes in tolls. However, increased tolls could cause the loss of current movement of about one million tons of iron ore and might affect long-run investment decisions in Labrador-Quebec iron ore sources. Increased tolls might also cause the loss of marginal grain shipments. A six-week lengthening of the Seaway and Great Lakes navigation season could be expected to result in increased tonnage for two traffic components. General cargo tonnage would probably increase 10 to 15 percent with an extension of either or both ends of the season. Annual grain traffic would probably be increased more than proportionately by a later winter closing of the shipping season. (Author)
