The economic turmoil that prevails during the 1930s leads the commanders of the Order of Jacques-Cartier in ACADIE to ensure the economic recovery of the Acadians. Their programme is to encourage colonisation, the development of credit, sales and purchasing cooperatives and to carry out national economic education. By means of nucleation — interference by associations — and externalisation — dissemination of ideas in the public space — commanders manage to achieve a large part of these objectives. The Order’s economic project aims to anchor settlers on the ground to prevent them migrating outside Canada or to Anglo-Protestant urban centres, to own their own economic institutions and to promote Canadian and French Catholic values. By contributing to national cultural development while drawing inspiration from the values and ideas of the same national culture, the project promoted by the commanders proves to be Catholic economic nationalism between Canada and France.
