Toponyms are true evidence of the presence of human groups who find in them one of the cements of their identity and solidarity. Toponyms are arguments of cultural validation and territorial legitimacy. The French toponymy that emerged over the past three centuries in the Canadian Prairie Provinces test to the passage and settlement of Francophones in the heart of the North American continent. This French toponymy, so abundant in the past, is no longer helping to build the habitus of the French-speaking endogroups. That is why, moved by the desire to keep this toponymic treasure alive and perennial in Francophone cultural literacy, we have been undertaking a long-term research for the exhumation, identification, recording, and dissemination of this French toponymy.
