History of the Association

On February 14th, 1947, a group of geologists met at the Engineers’ Club in Toronto with the objective of creating the Geological Institute of Canada, an association of geologists which would, among other things, promote, discuss and disseminate geological knowledge. A second meeting on March 11th, 1947, resulted in a preliminary Constitution and Bylaws as well as the election of the first Councillors, a change of name to the Geological Association of Canada and 140 charter members. From the outset, the Association was designed to fill a role similar to that of the Geological Society of America, bridging a gap between the perceived industrial mineral orientation of the Geological Division of the Canadian Institute of Mining and Metallurgy, and the purely scientific objectives of Section IV of the Royal Society of Canada.

Membership in the GAC® has expanded from a predominantly mineral-oriented, Toronto-based group to a truly national body with representatives in three territories and all provinces, with a reasonable membership in the United States, Europe and in other parts of the world.
