That isn't quite what happened...
The Executive Committee has authorized the City Manager to conduct public consultations across Toronto, and to report on the results of these consultations, along with more information on a recommended location, alternate locations, revenues generated from the recommended and alternate locations, and hosting fees.
The above report will be brought to Executive Committee in Feb/Mar 2013, and likely to full Council the following month.
The final decision on a casino in Toronto is thus still a few months off at a minimum.
The full "decision" is available here:
