Did You Know?

Your support in staying at the Sheraton Centre Toronto Hotel helps keep the conference costs down, which directly affects your registration fees. SIAM guarantees the hotel that we will fill a certain number of “room nights” (rooms per night) during the conference. SIAM incurs penalties if too many attendees opt to stay in other hotels in the area or neglect to indicate to the hotel that they are with the SIAM conference. At this time, conference costs do not include meeting room rental. If SIAM fails to fill the contracted room block, SIAM is charged the cost for the meeting rooms on a daily basis, along with a hefty penalty. Future registration fees could increase to cover these additional risks.


SIAM is holding a block of rooms at the Sheraton Centre Toronto Hotel. These rooms are being held on a first-come, first-served basis at the following discounted rates. Please be aware the room block fills quickly, so we suggest you make your hotel and travel plans early.

The group rate is guaranteed until the cutoff date or until the room block is full. If rooms are available after the cutoff date, they will be offered at the best available rate.

Reservation Deadline – Friday, June 5, 2020 at 5:00 p.m. local time (or until the room block is filled)
Single/Double Room Rate*: $249++ CAD per night, plus 17% tax
Student Rate: $230++ CAD per night plus 17% tax
Student ID must be presented upon check-in. SIAM is able to negotiate a limited number of special student rate rooms. Please book early as these rooms sell out quickly!

Room rates include complimentary internet access.
All rooms based on availability.
All rates are subject to state and local occupancy taxes.
*Additional fees of $30 CAD per person apply to triple and quad occupancy.

In the event that you find a lower room rate, please make the reservation at the lower rate and notify SIAM immediately. By doing this you will receive the lower rate and be counted towards the SIAM room block.  However, please be aware by booking outside the SIAM room block at a lower rate, you may not receive the same benefits as rooms reserved in the SIAM room block (i.e complimentary internet access).

In order to receive the SIAM rate, please make your reservations using the appropriate online reservation link or by calling the hotel directly and identifying yourself as a SIAM attendee:
Toll Free Reservations (U.S. and Canada): 888-627-7175 
Direct Telephone Number: +1-416-361-1000

Do not make your reservation online using the hotel’s general website, as this will not allow you to obtain the SIAM group rate. Be sure to use the online reservation link above if making reservations online. Remember to get your confirmation number!

Reservations are not confirmed until acknowledged in writing by the hotel or verified by phone. Be sure to get a confirmation number from the hotel and be prepared to provide that number to the front desk clerk upon check-in at the hotel.
