The headquarters for Canada’s largest stock markets will get a new home in the fall of 2017.

TMX Group Ltd. (TSX:X), the owner of the Toronto Stock Exchange, the TSX Venture Exchange, the Montreal Exchange and other securities markets, says it will move into a new, 40-storey tower that’s being built by Oxford Properties Group.

The new address at 100 Adelaide St. W in downtown Toronto is near the current Exchange Tower, which is a block south at 130 King St. W.

Oxford Properties Group says it will spend around $400 million to build the new 900,000-square-foot Ernst & Young Tower.

The existing building at 100 Adelaide St. W will be torn down, but its historic facade — including the mosaics made by Group of Seven artist J.E.H. MacDonald — will be integrated into the new structure.

Construction is expected to be finished by June 2017.
