Ottawa Marriott Hotel

Ottawa Marriott Hotel is a full-service hotel in downtown Ottawa, Ontario, Canada, at the northwest corner of Queen Street and Kent Street. Its central location places it within walking distance of Parliament Hill, the Château Laurier, the Rideau Canal, Rideau Centre, Shaw Centre, and the National Gallery of Canada. The property is positioned primarily for business, government, convention, leisure, and event travel rather than as a standalone consumer product brand. The building opened in 1972 as the Holiday Inn Ottawa Centre. It subsequently operated under the Radisson Hotels system as the Radisson Hotel Ottawa Centre before becoming part of Marriott Hotels & Resorts. The property is housed in a prominent downtown tower that was briefly Ottawa's tallest building during construction in 1971, before the nearby Place de Ville Tower C surpassed it. The building remains one of the taller structures in Ottawa and the National Capital Region. The hotel has 489 guestrooms and approximately 26,000 square feet of meeting space. Its facilities include a fitness centre, indoor pool, children's activity area, guest accommodation, and venues for meetings and private functions. Its best-known architectural and hospitality feature is the revolving upper-floor room. Originally associated with the La Ronde restaurant, the space later became Summit, a private event venue. It remains notable as Ottawa's only revolving room and completes approximately one rotation every two hours. The hotel underwent major main-floor renovations in 2010. These works included the closure of Cafe Toulouse and its replacement by spin Kitchen & Bar. The rooftop restaurant was also closed and later reopened as Summit, shifting the upper-level space from a conventional restaurant format toward private events. These changes adapted the property toward contemporary food-and-beverage, meeting, and group-event use while preserving its signature revolving-room feature. In 2023, the property was sold by Toronto-based InnVest Hotels to Manga Hotels Group, another Toronto-based hotel company. The ownership change did not alter the hotel's identification with Marriott Hotels & Resorts in the available reference material. As a named hotel property rather than a broad international hotel brand, its market presence is concentrated in Ottawa, with Marriott providing the customer-facing brand framework and reservation ecosystem.

The Ottawa Marriott Hotel occupies a prominent site at the northwest corner of Queen Street and Kent Street in downtown Ottawa. Its tower was under construction in 1971 and was briefly the tallest building in Ottawa during that period. The nearby Place de Ville Tower C exceeded it while that neighboring project was still being constructed, placing the hotel building within the development of Ottawa's modern downtown skyline. The property opened in 1972 as the Holiday Inn Ottawa Centre. Its initial identity connected it with the Holiday Inn system and with the growth of centrally located business and visitor accommodation in the capital. At a later stage, the hotel operated under Radisson Hotels as the Radisson Hotel Ottawa Centre. It eventually transitioned to the Marriott Hotels & Resorts system and became known as the Ottawa Marriott Hotel. The building's location has remained central to its commercial role. It is close to federal institutions and major visitor destinations, including Parliament Hill, the Château Laurier, the Rideau Canal, Rideau Centre, Shaw Centre, and the National Gallery of Canada. This setting supports a mix of government and corporate travel, convention activity, leisure stays, and private functions. The property is a large full-service hotel with 489 guestrooms and approximately 26,000 square feet of meeting space. In addition to accommodation and event facilities, it provides a fitness centre, indoor pool, and a children's activity area. These amenities give it a broader service offer than a limited-service lodging property and support both individual stays and group business. A distinctive element of the building is its revolving upper-floor room. The space was originally associated with the La Ronde restaurant, one of the hotel's recognizable features. In 2010, the property underwent substantial renovations to its main floor. Cafe Toulouse, the street-level restaurant, closed and was replaced by spin Kitchen & Bar. The rooftop restaurant also closed and later reopened as Summit, a private event space. Summit retained the revolving-room function, rotating at roughly one revolution every two hours, and is described in the reference material as Ottawa's only revolving room. The 2010 renovation therefore represented a change in how the property's food-and-beverage and upper-level facilities were used. Rather than retaining the former restaurant configuration, the hotel developed a refreshed main-floor dining concept and repositioned the revolving space for private events. The change preserved the building's most distinctive physical attribute while aligning it with meetings, receptions, and special occasions. In 2023, ownership changed when Toronto-based InnVest Hotels sold the hotel to Manga Hotels Group, also based in Toronto. The available reference material identifies the property as continuing under the Marriott Hotels & Resorts identity after the transaction. The Ottawa Marriott Hotel consequently combines a long operating history under several hotel systems with current Marriott branding, a downtown location, substantial meeting capacity, and a signature revolving event venue.
