Macdonald Block Reconstruction Project

About the Project:

The Macdonald Block Complex is the administrative hub of Ontario government operations, accommodating approximately 3,600 people. The complex is used as government offices and has a total rentable area of about 1.22 million rentable square feet.
Completed in 1971, the Macdonald Block Complex has never undergone a major renovation. The core systems, including electrical, water, cooling and heating, have reached the end of their useful life and must be replaced. The project involves the extensive reconstruction of the Macdonald Block Complex, which includes the Macdonald Block Podium, Hearst, Hepburn, Mowat and Ferguson Towers in Toronto.
This long-term project will take approximately eight years to complete.
The entire Macdonald Block Complex will remain publicly-owned.
IO will lead the procurement process for the project on behalf of the government and will be responsible for managing the project during the design and construction phases.
To meet the requirements of the Ministry of Infrastructure Public Work Class Environmental Assessment, IO has completed a Category B Class Environmental Assessment for the Macdonald Block Reconstruction Project.
The decant and reconstruction of the Macdonald Block Complex is part of the larger Queen's Park Reconstruction Project which includes the rehabilitation of the Whitney Block.

The Ministry of Infrastructure has identified the reconstruction of the Macdonald Block Complex as one of five pilot projects that will include community benefits.
