Applicant’s Proposal

The addition will add 159 hotel rooms, meeting rooms, an associated lobby area and an underground parking garage with 301 parking spaces to the existing hotel.

The development proposal retains the hotel in its entirety, and the addition will be built on the site of the former parking garage.  It consists of ten- and eleven-storey pavilions with a two-storey connector in between. The addition will connect to limited areas on the Château Laurier’s east and west wings. Exterior materials will be limestone, bronze and glass. 

The development proposal also includes a landscaped courtyard between the Château Laurier and the proposed addition, a redesigned forecourt along Mackenzie Avenue, a walkway and ramp along the north side of the addition, and a new stairway between the courtyard and the public terrace on the west side of the Rideau Canal.


The Château Laurier is designated under Part IV of the Ontario Heritage Act. For more information on the heritage aspects of this proposal, visit
