The origin of the Aquarium du Québec dates back to 1953, when Dr. Vadim D. Vladykov convinced Dr. Arthur Labrie, Deputy Minister of Ministry of Fisheries, to obtain a site near the Quebec Bridge that belonged to the Canadian National Railway. The provincial government acquired the land in 1954, and work to construct the buildings began in 1955. In 1956, the Biological Centre of Quebec opened, and included laboratories occupied by research teams in marine biology and fisheries, a rotunda, and two series of aquariums. Soon, a research wing was added to house laboratories for research on species with commercial potential, such as salmon, eel, and lobster, and to gather all documents in the library of the Ministry of Fisheries. 230,000 gallons of freshwater were supplied by tanker from Lake Saint-Charles and drawn directly from the St. Lawrence River. The 320,000 gallons of saltwater were brought in from as far away as Rimouski. In 1959, after the completion of reception areas and a restaurant, the aquarium opened to the public as the Organic Centre. The Organic Centre's educational mission was provided in collaboration with the Linnean Society of Quebec that establishes a program for children, a first for a museum in Quebec. The 150,000 visitors that were welcomed in the first year caused additional investment for the site that included outdoor pools for seals additional aquariums. In 1971, researchers at the Biological Centre eventually moved to the new Science Complex of Quebec. To reflect the fact that the aquarium had evolved into a public education facility, it changed its name to the Aquarium du Québec. In 1999, the aquarium welcomed its eight-millionth visitor. However, the facilities had become antiquated, and the Quebec government did not want to continue funding a facility that did not pay for itself. The Sépaq was created, with the mandate to manage and renovate the Aquarium, along with the Jardin Zoologique du Québec. In 2002, after two years of closure for renovation, the newly named le nouveau Parc Aquarium du Québec opened its doors next to the zoo. The main building, outdoor gardens, and seal pools were completely refurbished. Most of their international species replaced by aquatic species from Quebec. A polar bear exhibit with an underwater viewing pool was added, though the Aquarium was accused of having a design "off" from the definition of marine life, and of copying another popular attraction, the Zoo Sauvage de St-Félicien. The aquarium did not meet its ambitious attendance targets initially and it reduced its entry price and offered children of Quebec residents free admission until 2006. In 2005, Michel Després, the provincial minister responsible for the Quebec region announced that the Jardin Zoologique du Québec would close, some activities at the Aquarium would be stopped, and management would be turned over to the Société des établissements de plein air du Québec. The government of Quebec would invest $6.5 million at the aquarium to expand its collection. In November, 2008 the institution changed its name back to Aquarium du Québec and unveiled a new logo.

Indoors
;The Awesome Ocean The Awesome Ocean exhibit is the main attraction in the aquarium. Visitors walk through a tunnel in a sea water tank and see the marine life from the vantage point of a diver. There are often divers in the exhibit that will showcase the marine life. ;Discover the Coastal Zone This sector showcases the world of Canada's marine invertebrates from both the Atlantic and the Pacific Ocean. Visitors are also given the opportunity to interact and even touch the animals such as starfish, sea urchins, hermit crabs, sea cucumbers and more. ;Fresh & Salt Water Two levels of aquariums exhibit the estuarine life in the St. Lawrence basin where the fresh water from the river mixes with the salt water of the Atlantic Ocean. ;Scientific Crossroads Discover the research that makes the Aquarium du Québec an important place for marine biology in Canada and learn more about marine labs and marine research.
Outdoors
;Wetlands An exhibition that showcases the ecosystem of the St. Lawrence corridor that includes many birds, amphibians, insects, reptiles, and plants that inhabit the surrounding environment. ;Banks of the St. Lawrence River While visitors overlook the mighty St. Lawrence River, they can observe the grey and harbour seals as they frolic and play amongst the waves. ;The Arctic Sector Visitors can observe animals that exist in the Arctic, such as Harp seals, walruses, and polar bears as they move through the four different seasons with an underwater glass view. Visitors are also entertained with a daily walrus show that has two Pacific Walruses and one Atlantic Walrus. The Aquarium claims to be the first and only institution of its kind to care for the two subspecies.
