on June 15, 1956, with the ribbon being cut by federal Minister of Fisheries James Sinclair. Sinclair's daughter 7-year-old Margaret was also present at the ribbon cutting ceremony (she would later marry Canadian Prime Minister Pierre Elliott Trudeau and give birth to Canadian Prime Minister Justin Trudeau). Officially Canada's first public aquarium, the Vancouver Aquarium has become the largest in Canada and one of the five largest in North America. The Vancouver Aquarium was the second aquarium in the world to capture and display an orca. Other whales and dolphins on display included belugas, narwhals and dolphins. In 1975, the Vancouver Aquarium was the first aquarium accredited by the Association of Zoos and Aquariums (AZA). The aquarium is also accredited by the Canadian Association of Zoos and Aquariums (CAZA) and in 1987 was designated Canada's Pacific National Aquarium by the Canadian Federal Government. On July 23, 1995, a beluga whale named Qila was born. She was the first beluga to be both conceived and born in a Canadian aquarium. A second calf, Tuvaq, was born on July 30, 2002, but died unexpectedly with no previous sign of illness on July 17, 2005. In 1996, the Vancouver Park Board instituted a municipal bylaw that prevents the Vancouver Aquarium from capturing cetaceans from the wild for display purposes, and only obtain cetaceans from other facilities if they were born in captivity, captured before 1996 or were rescued and deemed un-releasable after this date. On June 15, 2006, Canada Post issued a 51 cent domestic rate stamp to commemorate the 50th anniversary of the aquarium. For many years, the primary attraction for visitors was the orca show. The aquarium was the second to capture a killer whale, Moby Doll, who was displayed for a day at Burrard Dry Dock on July 18, 1964. Subsequently, the public was kept away from him, however. Since then, it was home to Skana (at first called Walter), Hyak II, Finna, Bjossa, and three of Bjossa's calves. When Finna died and Bjossa was left without other orca companions, the aquarium attempted to acquire one or more female orcas from other marine parks. However, no suitable companions were found, and Bjossa was moved to SeaWorld, San Diego, in April 2001 where she later died due to a chronic respiratory illness. The aquarium has since moved to emphasize the educational aspects of the displays rather than the public spectacle of
