Department of Computer Science
University of Toronto
Toronto, Ontario, Canada

Room BA1190, 40 Saint George Street, Toronto

About: The Southern Ontario Numerical Analysis Day (SONAD) is an annual one-day conference that brings together researchers (faculty, graduate students, postdoctoral fellows, and other researchers, including those in the industry) working in the broad areas of numerical analysis and scientific computing at Ontario universities.
SONAD gives the opportunity to graduate students to present their work and exchange views on each others' work in a fairly informal setting, and to all participants to get together and discuss advances in the field.

Location: SONAD 2026 will take place in the Bahen Centre for Information Technology Building, room BA 1190, 40 St. George St, Toronto, Ontario, which is located in the University of Toronto Saint George campus.

Date: Friday, May 1, 2026, from 9:30 AM to 5:30 PM.

Invited speakers

Professors Ricardo Baptista (Statistics and Computer Science, U. of Toronto) and Hanno Rein (Physical and Environmental Sciences and Computer Science, U. of Toronto) have agreed to give the keynote lectures for the conference. Professor Baptista will talk on dynamical systems analysis of score-based diffusion models, and Professor Rein on the fastest N-body code in the world.
Here are the titles and abstracts of talks of all presentations.

Maps including parking

See the University of Toronto maps.
Click on "St. George Campus", then "Buildings", and type "BA" in the "Search" field, to see the location of the Bahen Centre for Information Technology.
Alternatively, go directly to the Bahen Centre for Information Technology (BA) link on the map.
The Bahen building is accessible by entrances at 40 St. George Street, and through an alley between the Fields Institute and the Koffler Student Services Centre (where UofT bookstore is).
Click on "St. George Campus", then "Transportation", then "Parking", then "Public Parking" to see the parking spaces. The closest one is within the Bahen Building (same building as the conference room) indexed as "Lot C - Bahen Centre Garage | BA".
Alternatively, go directly to the Bahen Centre for Information Technology Parking Garage link.
The garage is accessible through 213 Huron Street, Toronto, ON M5S 1A2, just north of College Street. You can park at any of the P2, P3 or P4 levels. (P1 is a truck lobby level with separate entrance.)
Cost is around $25 per day. Use the machines inside the garage to pay by CC.

Here is a map of the main floor of Bahen, showing the location of entrances to the building, washrooms, and water fountains. The BA1190 room is top left (north-west), with the main entrance in the main floor (blue arrow pointing top/north), and another entrance down the stairs.

Miscellaneous

A/V equipment, wi-fi:
The projector we'll being using for the SONAD talks has an HDMI plug with USB-C and mini-display-port connectors.
We will have a laptop also, so you can bring your talk in pdf on a USB key.
There is also a desktop PC available in the "teaching station" running Windows. There are some USB plugs on the teaching station, and they can be used if people bring their talk on a USB key. Bringing you talk in pdf on a USB key is always a good idea, even if you bring your own laptop.
Participants who are from various universities can connect to the Internet using the eduroam wireless network.
