GDG Environment Group operates three subsidiaries: GDG Environnement, for the biological control of biting flies and West Nile virus vector surveillance and control, GDG Aviation, for all aerial operations of the Group, and Diamond Sylvico, which is solidly implanted among the Cree communities of northern Quebec.

GDG Environment Group relies on extensive logistics resources for the implementation of its mandates, including taxonomy and molecular biology laboratories, a modern fleet of eight aircrafts (helicopters and airplanes), as well as more than 120 road vehicles.

For its country-wide operations, GDG Environment Group can count on a strong team of professionals and technicians which peaks at 200 during summer. The Group is now clearly positioned as the Canadian leader in the biological control of biting flies and in the management of disease vectors, with more than 500 successfully achieved mandates.
