Sébastien Laprise has cutting-edge expertise in the law applicable to public contracts. A strategic advisor, author and speaker in this area, he counsels and represents a number of public and para-public entities subject to the Act Respecting Contracting by Public Bodies as well as several municipalities and municipal bodies. His innovative approach helps his clients improve their contracting practices and better manage the upstream risks inherent in awarding contracts. Eager to share his expertise, thoughts and reflections, in 2011 he founded Contrats publics Québec, a public-procurement discussion group on LinkedIn which today has an ever-growing number of participants interested in keeping abreast of developments and best practices in this area.

He has published a manual on optimum strategies for municipal contracting, with Wolters Kluwer CCH entitled Contrat municipaux – Manuel sur les meilleures strategies, for use by officials in charge of awarding municipal contracts, as well as a companion guide entitled Contrat des organismes publics – Manuel sur les meilleures stratégies for the benefit of public bodies subject to the Act Respecting Contracting by Public Bodies
