Grande Bibliothèque

Literally the "Great Library", the Grande Bibliothèque is a building of Québec's National Library and Archives. It is conveniently located downtown, next to Montréal's busiest metro station.

We will have access to the auditorium and the adjacent M.450 room for our two tracks. Another smaller room will also be available for improvised meetings, discussions and presentations.


By Air

Montréal is served by the Pierre Elliott Trudeau International Airport, with connections to many major cities worldwide.

Traveling from the airport to downtown can be done by:

Public transit

It shouldn't be hard to find a hotel that is within walking distance from the venue, but should you need to go a bit further, Montréal's metro system is quite efficient. You'll find more information on the STM (Société de Transport de Montréal - Montreal Transit Corporation) website.

This is the logo you need to look for when looking for a metro station:
