The GAC-MAC Joint Annual Meeting, the premier annual geoscience conference in Canada over the last six decades, is organized by the Geological Association of Canada (GAC®), in concert with the Mineralogical Association of Canada (MAC). The two associations have long enjoyed a close relationship, and have united the Canadian earth sciences community annually at GAC-MAC, a formal gathering of the best geological minds in the country, to celebrate our achievements, discuss new findings and develop further relationships.
