Some people were late to register for the dinner, so could not be accommodated. If you want to be on a waiting list, please email

If sufficiently many people sign up, we can get a bigger room.The conference dinner will be held Thursday, May 16th at Le Sélect Bistro, an excellent French restaurant.

T-Shirts

What is a conference without a T-shirt to remember it by? Our design team has come up with the attached design.  We printed a sample shirt and were pleasantly surprised by the faithful representation of the colours of the waterfront skyline. We are offering the shirts at cost. They must be ordered in advance and paid for in cash at the conference. They will be between 25 and 35 dollars, depending on how many we order. THEY MUST BE ORDERED BY MIDNIGHT MAY 7th, E.S.T, so that they can be ready before the conference ends. Write to

specifying the size(s) and colour(s) of the shirt(s). Here is the size chart. Pay attention to it, since the sizes seem somewhat larger than these letters usually designate. All dimensions are in inches.

S (18/28)  width/length
M (20/29.25)
L (22/ 30.25)
XL (24/31.25)
2XL (26/32.5)
3XL (28/33.5)

The following background colours are available: black, maroon, metro blue.  The metro blue design is attached to this e-mail; the other two will be sent separately so that your mailbox will not simulate a gorged python.  The shirts are all 100% cotton.

 Abstracts

Speakers should send in their titles and abstracts so that we can schedule the lectures and compile an abstract booklet. To have you "slides" put on the computer in the lecture room, e-mail them with 'set theory talk' in the subject line to

Alternatively, speakers can bring a flash drive or their own computer, but the last alternative might raise compatibility issues. 

Accommodation and Travel

Information about accommodations, transportation, etc. can be found on the Fields Institute website: http://www.fields.utoronto.ca/resources/for-visitors

The price of accommodation in Toronto has risen sharply.  May is a peak season, so you need to book this as soon as possible.  If you can't find anything reasonable near the Fields Institute, a good alternative is to find a place easily accessible by public transit.  In general, west of the Fields is considerably cheaper than east of it.  There are streetcars on College St, Dundas St, and Spadina Ave, as well as subway lines under Bloor St and Yonge St, each of which will bring you within walking distance of the Fields.
Please be sure to ask for the University of Toronto corporate rate if booking at the Holiday Inn-Carlton.  The rate is about $220/night, including taxes.
If you are still looking for accommodations for the conference in May, Massey College (a graduate residence on the University of Toronto campus) rents rooms in the summer.  It will not be possible to book anything until early April (exact date of availability not yet available) but they will definitely be renting rooms for the dates of the conference.  If you are interested, please start checking the website https://www.masseycollege.ca/summer-rentals/ starting in April until it becomes possible to make reservations. To be safe, book something else now that you can cancel if you succeed with Massey (which only has about 20 rooms).

Those needing Canadian visas should apply well in advance.  We can supply letters of invitation upon request.
