To the east end of the complex is the 586-room InterContinental Toronto Centre hotel (formerly Canadian National Railway's L'Hotel CN).

According to a 2018 report, over the past 34 years, the MTCC has hosted over 20,000 events and has added CA$6.3 billion in direct spending economic impact to the community.

Based on the Ontario Tourism Regional Economic Impact Model (TREIM), the MTCC also sustained a record-breaking 7,622 jobs in the community in its 2017/18 fiscal year.

The convention centre and hotel was completed in 1984, built by CN Real Estate designed by Architects Crang and Boake.

A new largely underground addition, designed by Bregman + Hamann Architects, was added south of the railways, east of the CN Tower in 1997 to expand convention space.

[5] In October 2012, Oxford Properties proposed the re-development of the site with an updated convention centre, casino, hotel and retail complex.

[11] In 2011, on the occasion of Art Toronto the artist Achim Zeman presented an installation at the entrance-hall of the building called Str@del: Eight columns, walls, the ceiling and the reception were covered in red and matte white fluorescent foils.

The stripes, wide and narrow surrounded the architectural space, and because of their arrangement left the impression on the viewer as if he was experiencing countless whirlpools, which swirled around him.
