According to the Globe and Mail newspaper (February 16, 2007), after acquiring the property in 2003, high-profile Toronto developer Harry Stinson toyed with a skyscraper condo-hotel project for about a year, then withdrew it because, "It was not sufficiently sexy [in concept] to carry the sales."
On November 15, 2005, the Toronto and East York Community Council, a division of Toronto City Council, refused permission for the tower to be built on its proposed site. At issue was thin but inevitable shadow that would have been cast by the building over Nathan Phillips Square, site of Toronto's City Hall. Council argued that it needed to "protect city hall's public square." Stinson was to appeal the decision to the Ontario Municipal Board.
The design evolved to its proposed height in response to the approval of the Trump International Hotel & Tower by the city council. Stinson intended to create a friendly rivalry between himself and famous developer Donald Trump for the tallest residential building in Canada. Sapphire Tower would have been 17 metres taller.
In early January 2006, Harry Stinson announced his intent to compromise with city council. Instead of a more than 90 storey building, the focus shifted to designing a shorter building of approximately 70 storeys, with a slanted roof that would further minimize the shadow concerns.
Sapphire Tower was originally to be operated much like Stinson's earlier hotel project 1 King West. Each of the over 1,000 suites was to be individually owned by its purchaser, with the opportunity of generating revenue through enrolment in a central management system.
Facing high levels of dissent from 1 King West owners at the hotel's lack of profitability, Stinson has decided not to offer the same system to Sapphire Tower purchasers. Instead, the building will now consist primarily of private residences, where the purchaser may occupy the suite or lease it out themselves in a traditional fashion. There will be a small hotel component to the building of roughly 200 suites, but they will be retained and operated by Stinson himself. With all the design and use changes, a new name to replace "Sapphire Tower" was expected but did not occur.
On July 20, 2007, Sapphire Tower Development Corp., the parent company fully owned by Harry Stinson, was approved for bankruptcy protection. All future plans of development for the Sapphire Tower were stopped. Sapphire Tower Development Corp. is currently listing the development (including land) for sale to respective buyers in order to repay creditors.
