The CN Tower (French: Tour CN) is a 553.33 m-high (1,815.4 ft) concrete communications and observation tower in Downtown Toronto, Ontario, Canada. Built on the former Railway Lands, it was completed in 1976, becoming the world's tallest free-standing structure and world's tallest tower at the time. It held both records for 34 years until the completion of Burj Khalifa and Canton Tower in 2010. It remains the tallest free-standing structure in the Western Hemisphere, a signature icon of Toronto's skyline, and a symbol of Canada, attracting more than two million international visitors annually.

Ripley's Aquarium of Canada is an aquarium in Toronto, Canada. Owned by Ripley Entertainment, the aquarium opened to the public on Wednesday, October 16, 2013.

Located at the base of the CN Tower, it connects directly with the SkyWalk and the aquarium is home to 16,000 animals. The aquarium holds 5.7 million litres (1.5 million gallons) of water and shows marine and freshwater habitats from around the world. The building features a multi-facetted shell clad in large aluminum panels, with the roof of the main entrance that "gives the illusion of the earth’s crust peeling away to reveal a window into the aquatic world. There are also coloured surfaces that juxtapose reflective aluminum soffits, per the architects.
