Year after year, Otakuthon has occupied more and more conference spaces and hallways of the convention center following an annual progressive growth; while in 2008 less than half of the 5th and 7th floors were booked, in 2010 nearly 80% of those floors plus the main exhibition hall of the 2nd floor (for Registration) were open for the convention.
This allowed the convention to increase its capacity, concentrate the main attractions on a single floor instead of multiple floors at the university, as well as free itself from restrictions imposed upon by the institution.
In the same year, Otaku Anime and the other anime clubs managing the convention formed the Quebec Anime Committee, Otakuthon's parent organization.
