Aquarius at Waterpark City is a 38-storey high-rise condominium built in 2006 by three major Toronto developers: H&R Developments, Lanterra Developments, and Lifetime Developments. The building contains 490 units, making it a substantial residential community. The tower was designed to serve a broad market, with units ranging from one to three bedrooms and averaging around 589 square feet. As a pre-construction and mid-cycle building, it reflects early 2000s condo design and functionality. The building maintains a no-pet policy, which is an important consideration for animal owners evaluating the property.

Aquarius is situated in Toronto's Niagara neighbourhood, positioned near King West and Simcoe Street in the M5V postal area. The location offers strong transit connectivity, with St. Andrew subway station within walking distance and streetcar service on nearby King Street providing direct access across the downtown core. The area is mixed-use, with retail, dining, and entertainment options throughout the Entertainment District and close to St. Lawrence. Residents enjoy walkable streets with galleries, markets, and waterfront access via the Harbour. This neighbourhood appeals to people who prioritize downtown convenience and public transit over car dependency.

Units in Aquarius average 589 square feet and typically offer one to three bedrooms, accommodating a range of household sizes. Current market listings show units priced from $459,000 to $650,000 for purchase, with rental units averaging $2,693 per month, giving a sense of the building's market position. When evaluating a unit, consider maintenance fees, which are a regular expense in high-rise condos, and review the building's reserve fund status and condo financial statements. The building offers resident amenities including a fitness centre, swimming pool, sauna, whirlpool, and yoga studios, plus landscaped gardens and a courtyard for outdoor space. Prospective tenants and owners should confirm unit-specific features, view windows and light, and assess parking availability, as downtown Toronto often has limited parking options.
