In 1980, the owner became Jean-Claude Tremblay who pushed the company one step further with his personalized approach, and the quality offered with his services. A second seaplane base, Chutes-des-Passes/Lac Margane Water Aerodrome was opened at Chute-des-Passes in 1982. It was a strategic location to access new territories for fishing and moose hunting and to better position himself toward the north. 1984 was a major year for the expansion of Air Saguenay. It purchased Air Caribou in Fermont and also purchased Club Chambeaux outfitters which gave him access to great fishing and caribou hunting in Northern Quebec. In 1986, the growth continued with the addition of a new seaplane base in Schefferville. He also purchased many other small bush operators in the 1990s, to reinforce the position of his company all over Northern Quebec.
