Canada's Great Lakes shipbuilding industry marched into its postwar era Saturday with the keel laying of the first peacetime ship since 1939 in the great Collingwood shipyards, where 40 wartime vessels were built and launched, the last one on Thursday. Here is the stern section of the keel for "Norisle," 214-foot steel ferry. Deck scene on Diesel-engined C-Class coaster "Ottawa May Brook," now being fitted out after launching Thursday. With three sister ships in yard basin, she will be delivered to Wartime Shipping, Montreal, probably to be sold at auction after originally being intended for the China-India coastal run.
