TORONTO - Infrastructure Ontario (IO) has issued a Request for Proposals (RFP) to three shortlisted teams to design, build, finance and maintain the Macdonald Block Complex. The 45-year old Macdonald Block, a complex of four towers, has never undergone a major renovation and its core systems - including electrical, water, cooling and heating - have reached the end of their useful life and must now be replaced.

Teams were selected based on criteria identified in the Request for Qualifications process that began in August 2017. Selection criteria included applicable design and construction experience, as well as the qualified personnel and financial capacity to deliver a project of this size and complexity.

The shortlisted teams are:

EllisDon Infrastructure

Developer: EllisDon Capital Inc.
Construction Team: EllisDon Design Build Inc.
Design Team: NORR Limited
Facilities Management: EllisDon Facilities Services Inc.
Financial Advisor: EllisDon Capital Inc.

Fengate PCL Progress Partners

Developer: Fengate Capital and PCL Investments
Construction Team: PCL Constructors
Design Team: WZMH Architects
Facilities Management: Johnson Controls
Financial Advisor: Fengate Capital

Sandfield Partnership Solutions

Developer: Brookfield Financial Corp. / Ledcor Developments Ltd. / Walsh Infrastructure Canada, Ltd.
Construction Team: Ledcor Design-Build (Ontario) Inc. and Walsh Canada
Design Team: B+H Architects
Facilities Management: BGIS Global Integrated Solutions
Financial Advisor: Brookfield Financial Corp., Ledcor Developments Ltd. and Walsh Infrastructure Canada, Ltd.

Teams invited to respond to the RFP will begin preparing proposals that detail how they will design, build, finance and maintain the project. Once submissions are received, IO will evaluate the proposals, select a preferred bidder and then negotiate a final contract. A successful bidder is expected to be announced in spring 2019. A fairness monitor will oversee the entire procurement process.

The newly reconstructed complex will meet current building, health, safety and accessibility standards, facilitate a more efficient use of space and help the province meet its greenhouse gas reduction targets.

IO and the Ministry of Infrastructure are working together to deliver the reconstructed Macdonald Block Complex, which will remain publicly owned.

Quick Facts:

  • The Macdonald Block Complex includes the Macdonald Block Podium, and the Hearst, Hepburn, Mowat and Ferguson towers.
  • An independent, third-party expert panel concluded that the extensive reconstruction is needed.
  • The reconstruction of the Macdonald Block Complex project will reduce the cost of government operations and help the province meet its greenhouse gas reduction targets.
  • The project is being delivered using IO's Alternative Financing and Procurement (AFP) model, an innovative way of financing and procuring large, complex public infrastructure projects.


“Reconstructing the Macdonald Block Complex will reduce the cost of government operations and help the province meet its greenhouse gas reduction targets. The reconstruction is a long-term project that will be undertaken in a fiscally responsible manner. When completed, it will have a significant economic benefit to the province over the next 50 years.”
Bob Chiarelli, Minister of Infrastructure

“This is a significant milestone in our process to select the best team to reconstruct the Macdonald Block Complex - a critical hub of Ontario government operations. We look forward to reviewing and evaluating the proposals developed by each of the shortlisted teams.”
Ehren Cory, President and CEO, Infrastructure Ontario
