| The industry of international air transport has been transformed since the 1980s by the combined forces of liberalization, competition and privatization. The development of air cargo has proven to be a characteristic of the globalization of markets. Institutional reforms of the 1990s in the air transport sector gave an impetus to air cargo. This has fostered a reorganization of the strategies of airport terminal operators, air carriers and the logistics community. Generally speaking, literature deals with individual players in the airline industry, highlighting their respective performances. However, their activities are interdependent in their functioning.;The originality of this research consists in establishing a relational model between airport terminal operators, air carriers and the logistics community. From a theoretical point of view, this model allows a better understanding of the relationships between each actor. From an empirical point of view, the model establishes a portrait of the air cargo industry in Canada. The research methodology consists in analyzing each of the players in the air cargo industry in Vancouver, Montreal and Toronto in terms of investment, network performance and products carried. The synthesis of this analysis assesses the structure and gives a portrait of the air cargo industry in Canada.;Keywords: Transport Geography, air transport, airport terminal operator, air cargo, logistics, Air Canada, Canada.;The aim of the thesis is to adopt an approach based on the concept of network operators involving an analysis of the relationships between the three actors of air cargo namely, the airport terminal operators, air carriers and the logistic community. Three research questions have been identified and applied to the air cargo industry in Canada: (1) An issue on how institutional stakeholders of the airline industry govern the freight transport; (2) An organizational issue to determine how the air cargo industry meets the requirements of market economy; (3) An issue to determine how operational conditions affect local responses and actions of players in their system of air cargo delivery. |
