Our host hotel is the Sheraton Toronto Centre, a CAA/AAA Four Diamond hotel in the heart of downtown Toronto. Located at Queen Street West and Bay Street, the hotel is just steps away from Toronto’s best attractions, shopping, theatres, dining and museums and is connected to the financial and entertainment districts by way of the PATH, a 16-mile underground network of shops and services. 

Parking is available at the hotel or at one of several underground locations including Toronto’s City Hall, located immediately across the hotel.

We ask all delegates to use the hotel block we have reserved for you until March 10, 2017. By using the room block and not booking at an alternate hotel, you are directly supporting OAO in avoiding financial penalties for low reservation numbers.
