Starting in January 2024, the AGO Library will be open to the public on Wednesdays from 1:00 pm to 5:00 pm, and by appointment on Thursdays and Fridays. Saturday, Sunday, Monday and Tuesday we are closed.

Access to rare books, archives and special collections is always by appointment.

To request an appointment, please send an email to [email protected] with a brief description of your topic of research, and the date and time that you would like to use the library. A librarian will contact you to arrange the details of your visit. Appointments may also be made by leaving a phone message at 416-979-6642.
