Established in 1977, the Colloquium Lecture is an annual commissioned presentation and paper. It is targeted to a younger member of the CGS, typically 40 years of age at the time of the nomination, to provide information of particular interest to the geotechnical community on topics of importance to the Canadian geotechnical field. Its purpose is to encourage and provide an opportunity for a younger member of the CGS to pursue studies required for its preparation. It is presented at the annual Canadian Geotechnical Conference.
Since 2016, the Colloquium Speaker has also been offered the opportunity to present their Colloquium Lecture at various locations across Canada through the Colloquium Lecture Series. It is preferred that the lectures be presented in a University setting with effort devoted to encouraging participation of undergraduate and graduate students.
