The Macdonald Block Complex is the administrative hub of Ontario government operations and employs 3,600 people. The complex is used as government offices and has a total rentable area of about 1.22 million rentable square feet per Infrastructure Ontario.

The complex was completed in 1971 and has never undergone a major renovation. The core systems which include electrical, water, cooling and heating have reached the end of their useful life and should be replaced. Extensive reconstruction of the Macdonald Block Complex includes the Macdonald Block Podium, Hearst, Hepburn, Mowat and Ferguson Towers in Toronto.

According to Ontario Construction Report, Infrastructure Ontario reported that three teams have submitted bids to design, build, finance and maintain the Macdonald Block Complex.

The following teams responded to a request for proposals:

 - Ellis Don Infrastructure

 - Fengate PCL Progress Partners

 - Sandfield

The proposals will be evaluated by Infrastructure Ontario and the Ministry of Government and Consumer Services. They will select a preferred bidder and then negotiate a final contract. A fairness monitor is overseeing the entire procurement process and a successful bidder will be announced in mid-2019.
