Geological Survey of Canada: Executive Directors and program leads

The Geological Survey of Canada (GSC) is Canada’s national organization for geoscientific research and information. Our scientists run programs and labs across the country. Below is the contact information for our director general, regional directors and program leads.

Our Science Laboratory Network includes five lab groups across Canada, each of which has its own area of lab-based research expertise. You can read about our labs and the earth material collection here. If you want to connect with other geophysicists, geochemists, seismologists, mathematical geologists and more, consult the directory of scientists or the GCdirectory.
