The project filed for development permit application is called The Bow, for its crescent shape and the view of the Bow River.
 On October 12, 2006, Foster + Partners revealed the first designs for the new tower.

Plans called for the project to house two separate companies, both equally occupying the space: Encana Natural Gas, with over 3,000 Calgary-based employees; and Cenovus Energy's more than 3,600 Calgary-based staff.
 Both companies were located at multiple sites throughout the downtown core.
With an estimated 158,000-square-metre total office space, the complex was expected to be the city's largest.
 Construction started in June 2007, and the building opened in June 2013 with a final cost of $1.4 billion.
The tower was lowered down to 236 m due to shadowing concerns and is the 149th tallest building in the world.

On February 9, 2007, EnCana sold The Bow office project assets to H&R Real Estate Investment Trust for $70 million, while signing a 25-year tenant lease agreement that was to start after the project's completion.

In late June 2007, the company announced that the Portrait Gallery of Canada would not be moving from Ottawa into the Bow.
