The CBC Ottawa Production Centre is the headquarters of the Canadian Broadcasting Corporation. The office and studio complex is located on Queen Street in downtown Ottawa, Ontario, Canada. The building hosts the originating studios for both the CBC's English and French language operations in the National Capital Region. The building was opened in 2004, and contains approximately of office space. Design and construction The Ottawa Production Centre was built by and is owned by Morguard Investments. Not all of it is leased by the CBC, with the top floors occupied by the House of Commons administration (Information Services). It is located at 181 Queen Street, between Bank Street and O'Connor Street (across from the Confederation Line light rail station) in the city's downtown core. The rear of the building backs out on the Sparks Street pedestrian mall. The site had been vacant for several years and had previously been home to a Woolworth's department store. Several of the studios and the newsroom are located at ground level on Sparks Street, allowing the public to observe from outside through high windows. Eight different CBC News services, consisting of 200 editorial staff in the National Capital Region, operate in both English and French out of the main newsroom to produce content for radio, television and the internet. The main design feature of the Production Centre is that it appears as a typical multi-storey office building on the Queen Street frontage, whereas the Sparks Street frontage is consistent with the low-rise development on the pedestrian mall. Given the significant terracing of the building's Sparks Street façade above the fourth floor and the grade differential between Queen Street and Sparks Street, the building is 12 storeys on Queen Street, but appears to be only four storeys in height from ground level on Sparks Street. Although the building was designed to revitalize Sparks Street, critic Rhys Phillips described the building as "just another low-cost, banal building." Visitors and non-CBC employees working on the building's upper floors must access the building from Queen Street, thus directing pedestrians away from the pedestrian mall. A pathway linking the Queen Street lobby to Sparks Street was cut from the original design to make room for a larger newsroom. Councillor Diane Holmes called the building "the biggest disappointment" and "a whole block of deadness."
