We invite you to join us in Montreal next October for a weekend meeting in Category Theory, the "not-quite-annual" OctoberFest. As has been the tradition with these meetings, we invite talks from all participants. If you wish to give a talk, send your request along with a short abstract (well before the end of September please) to Robert Seely at the address below. The final schedule of talks will be handed out at the meeting, but a provisional schedule should be available on this webpage, if possible, before the meeting.

Please let us know if you intend to join us by sending a short email (before the end of September if possible) to Robert Seely.


We will meet in Concordia's Faubourg building ("FG" on the Concordia map) on Saturday morning, October 4th. The FG building is located at 1616 St. Catherine W., corner of St Mathieu (see the Campus map).
Lectures will be in room FGB040 in the basement of the FG building. To access this, the easiest way is via the Ste Catherine St entrance opposite Pierce St, then go two floors down.
Check this map for more explicit instructions, and we'll post signs to help on the day.
Coffee will be available from 8:30 am. The first talk will be at 9:15.

Information re parking

Concordia has an indoor parking garage in the LB (Library) building, 1436 Mackay, near the site of the talks - the daily rate on weekends is only $6.


There will be a registration fee of $20 (in Canadian dollars preferably, but US will be accepted in emergency) to cover refreshments and sundries. (Exact change please.) Registration will take place during Saturday morning, before the first talk and during the first coffee break.

Local Information

There will be a buffet lunch on Saturday at a local Indian restaurant (participants responsable for their own costs). Some recommendations for dinner will be available, but participants are officially on their own(!) in the evening.

Below you will find a list of hotels and tourist rooms close to Concordia. We've provided links to those that ought to be the most suitable. Please note that October is a popular month for visiting Montreal, and early booking is recommended.
I have added some links in the hotels and tourist rooms section to budget accomodation, which might be suitable for some attendees.
If you have any further questions, please contact one of us.

We have received a bit of money from Concordia Univeristy towards the Octoberfest and have decided that we would like to help out graduate students who wish to attend. So any grad student who is planning to attend and would like support should write to Robert Seely by Sept 15 at the latest and make a request. We may or may not be able to help with travel expenses, but we should be able to pay for local hotel bills, although everything depends on how many applicants. Participants will have to submit original bills to be reimbursed. Sorry, but it will be impossible to provide money beforehand.


It can be warm, cold, wet, dry ... anything is possible in October. We suggest you check the forcast for Montreal:
