This co-operative venture by thirty-eight leading Canadian lawyers, jurists, and scholars is the first published survey on a major scale to cover nearly all aspects of Canadian relations with international organization. In recent years active Canadian involvement in controversies exercising major intergovernmental organizations and raising complex questions of international law has burgeoned to the point that Canada's role often far exceeds what might normally be expected of a middle power with a limited population. In some cases Canada has taken a leading part comparable to the major powers. This Canadian activity, variously applauded as creative or rejected as dangerous, is reviewed and assessed in these pages. More than a factual recitation of events, this volume attempts to explain why the Candian approach developed as it did and what factors, or patterns, are exerting perceivable influences on the prsent shaping of policy. Unusual in the vast scopt of the subject matter, the work covers such topics as: the constitution and functioning of international organizations; this relations of individuals and corporations with states other than those of which they are nationals; multinational corporations; control of the extraterritorial activities of individuals and corporations; pollution of the air, the fresh waters, and the ocean; the sea bed, the continental shelf, and the conservation of the fisheries. This volume is impressive recognition of the work done by Canadian lawyers in contributing during recent years to questions of jurisprudence among the nations of the world.
