The St. Regis Toronto

The St. Regis Toronto is a mixed-use skyscraper located in the downtown core of Toronto, Ontario, Canada. It was built by Markham-based Talon International Development Inc., which is owned by Canadian businessmen Val Levitan and Alex Shnaider. The hotel portion of the building is owned by InnVest Hotels LP, which acquired it iname17

The building is located in Toronto's Financial District, at 325 Bay Street, on the southeast corner of Bay and Adelaide streets. Including the spire, it is the second-tallest building in Canada, the tallest mixed-use building in Toronto and the fourth-tallest structure in Toronto, as of 2020.

The building opened in 2012 as the Trump International Hotel and Tower Toronto. The Trump family-owned The Trump Organization held the management contract for the hotel and was a minority shareholder in the project. This affiliation with Donald Trump – then a real estate developer and reality-television star, later President of the United States – was controversial, and led to public calls to drop the building's Trump branding.

The management contract was bought out by JCF Capital in June 2017, and the hotel portion of the building was then purchased by InnVest Hotels LP, a subsidiary of Bluesky Hotels and Resorts. The hotel management shifted to Marriott International, which operated it on an unbranded basis as The Adelaide Hotel Toronto during renovations. After the renovations were completed, the hotel became part of Marriott's St. Regis Hotels & Resorts on 28 November 2018, adopting its present name
