Allied and Westbank have initiated construction of a new structure on 19 Duncan, which they intend to integrate fully with the heritage structure. To be called Duncan House, the integrated structures will be comprised of approximately 146,000 square feet of office GLA, 21,000 square feet of retail GLA and 462 rental residential units. Allied and Westbank have designed Duncan House to a LEED (Leadership in Energy and Environmental Design) CS (Core & Shell) Gold standard.

Thomson Reuters has agreed to lease approximately 146,000 square feet of office GLA in Duncan House as its Toronto Technology Centre for a term of 12 years with occupancy scheduled to commence in early 2021. In a press release issued earlier today, Thomson Reuters stated: "The offices will feature a collaborative workplace environment designed to promote employee health and wellbeing. It will feature both formal and informal workspaces designed to enable a variety of working styles, supported by state-of-the-art technology, breakout spaces, exterior terraces and food service. The Centre's amenities will include a café, health club, bicycle room and on-site concierge services."

"Allied and Westbank look forward to ongoing collaboration with Thomson Reuters in meeting its workspace needs at Duncan House," said Tom Burns, Allied's Executive Vice President and COO. "We see this as a strategic partnership among three leading Canadian organizations intent on contributing to the commercial and social evolution of Downtown Toronto."
