In the recent context in which Quebec municipalities have been recognized as local governments, elected municipal officials have become key players in the development of their communities. The question of their relationship with various types of knowledge deserves scrutiny in order to better understand their practice of municipal politics in interaction with other actors in the local development arena: citizens, municipal staff as well as community and scientific actors, and business people. We conducted an exploratory study to identify trends in this relationship. Our results point to a certain transformation of the interests of municipal representatives towards complex development issues, whether these interests appear before or after knowledge acquisition. They also indicate a high degree of appreciation of citizens’ knowledge on the part of elected officials, although this does not seem to translate into significant reference to citizens’ input. In addition, it seems that bridges still need to be built between municipal councillors and various groups holding specific knowledge, mainly actors from the scientific community.
