The '''C.D. Howe Building''' (French: '''Édifice C.D.-Howe''') is an office tower in [[Ottawa|Ottawa, Ontario]], Canada, that is the home of [[Innovation, Science and Economic Development Canada]], the Office of the [[Auditor General of Canada|Auditor General]] and other smaller tenants. It was built by [[Olympia and York]]. The federal government sold the land to O&Y for a dollar and signed an agreement to lease the final building for a set rate until 2012. The eleven-story building was opened in 1978. The building site was once The Embassy Restaurant from 1953 to 1974.<ref>{{Cite web |date=June 28, 2025 |title=The Embassy Restaurant |url=https://www.historynerds.ca/2016/06/28/the-embassy-restaurant-1953/ |website=www.historynerds.ca}}</ref>

== Description ==

It was named after [[C. D. Howe]], a noted federal minister in the 1930s, 1940s and 1950s.  It is located at the prominent intersection of [[Bank Street (Ottawa)|Bank Street]] and [[Sparks Street]].  The lower levels of the building contain a  [[shopping mall]] named '''240 Sparks'''. The mall covers 3 floors with 50 stores including a [[Holt Renfrew]] store<ref>{{Cite web |url=http://240sparks.com/history/c-d-howe-building/ |title=History - C. D.

The most notable element of the building's interior is the amount of greenery and the large [[waterfall]]. Public Works and Government Services greened the rooftop to address environmental concerns including energy conservation, storm water management, biodiversity, and air quality, and to provide the occupants a landscaped tranquil outdoor space. More than 30% of the roof is landscaped and grows indigenous flowers, grasses and shrubs. Another 30% of the rooftop uses green roof technology. The C.D. Howe Building was included amongst other architecturally interesting and historically significant buildings in [[Doors Open Ottawa]] in both 2012 and 2014.<ref>{{Cite web |last=Recreation |first=Cultural and Facility Services |date=2024-06-11 |title=Doors Open Ottawa |url=https://ottawa.ca/en/arts-heritage-and-events/doors-open-ottawa#section-5cecae4b-6914-464a-a7a2-cd376255879f |access-date=2025-03-19 |website=ottawa.ca |language=en}}</ref>
  
The two [[elevator]] banks contain two storey tall cars that rise in a large atrium that stretches the entire height of the building.
