Situated below a major 17-acre urban park created as part of the project, this expansion doubles the Centre's exhibit space to 460,000 square feet and includes meeting rooms, registration and pre-function areas, and service areas. The entrance pavilion's dynamic form is composed of a series of drum-shaped volumes articulated with steel, glass, and granite elements. An elliptical skylight provides daylight to all major levels below and frames a dramatic view of the CN Tower from the Registration level.

The existing Centre and Expansion are linked by both a tunnel and bridge across a rail corridor. The project also includes high-performance sustainable design features. *Award: 1999 Ontario Association of Architects, Award of Excellence.
