Schoch decided to open a new seaplane base, Lac Sébastien Water Aerodrome at St-David de Falardeau, Lake Sebastien, to offer a better service to companies like Alcan or Price Brothers, fishermen, hunters and services for forest fire patrol.

Tremblay also purchased many other small bush operators in the 1990s, to reinforce the position of his company throughout Northern Quebec.
