Blanchard's many intuitions concerning the connection between different modes of production and the prominent part played by the family in the reproduction of « ways of life » distinguish him from the dominant determinism of French geography at the turn of the century, making him very close to the actual concerns of geography on that matter. Blanchard's contribution to the knowledge of the regions of Québec took a long time to fructify because of the lack of interest of geographers who, inspired during the sixties by the new Anglo-Saxon paradigm turned their back away from the regions to privilege the policies and methods of regionalization and regional planning. Nowaday, facing the failure of these policies and methods, geographers rediscover the importance of the relations established by the social actors on local and regional levels, which brings a renewal to regional geography. Blanchard's contribution reveals itself very actual, considering the importance taken by the notion of « life style » in this renewal.
