sentences:  In 1986, O&Y sold the Bay Street property to Cadillac Fairview and The Toronto Dominion Bank (Toronto-Dominion Centre West Limited), conditional on the design centre concept being retained.The new owner was also required to provide $500,000 to the City for 25 years, which would, in turn, be passed along (minus a 10% holdback) onto the design centre to offset operating costs.This agreement, in effect, gave the Design Exchange operating rights in the historic building.
