Telus Tower, Commercial skyscraper in downtown Toronto, Canada

Telus Tower is a 30-storey office skyscraper at 25 York Street, at the corner of York Street and Bremner Boulevard on former railway lands just south of Union Station. It rises 121.7 metres, or 136.1 metres with its antenna, and was designed by Adamson Associates and Sweeny&Co Architects.

Built on former railway lands south of Union Station, the tower was completed in 2009 after three years of construction. Menkes Developments Ltd. managed the project with Alcion Ventures and HOOPP Realty Inc., while Sweeny&Co Architects and Adamson Associates served as lead architects. It rose alongside taller neighbours such as the RBC Centre and Bay-Adelaide Centre.

The tower's name comes from Telus, the Canadian telecom operator whose Ontario headquarters it houses at 25 York Street. Telus occupies 21 of the 30 storeys, three of which are given over to fun and wellness spaces for staff. Other tenants include Dye & Durham, President's Choice Financial, Kinross Gold and Hudbay Minerals.

The building connects directly to Toronto's PATH network, allowing year-round covered movement throughout the downtown core. With 15 elevators throughout the structure, vertical traffic handling is efficient for daily users and visitors.

Telus occupies 21 of the tower's 30 storeys, about 70 percent, and three of those floors are given over to fun and wellness spaces for staff. In 2021 the building received BOMA BEST Platinum certification with a score of 99.2 percent, then the highest score worldwide.
