There will be one major event this weekend, the Comicon De Quebec at the Centre de Congres De Quebec from October 9th to the 11th, 2026. And ticket prices vary, depending on the day(s) and/or event(s) one attends. (click here for information).
There are major bus stops next to this venue because it on a major corridor and near the Parliamentary Buildings of the province, bus stop 1517 being the closest operating stop. But it appears that there are some detours due to construction in the area so you will probably want to consult the RTC’s official site.
Cash may be preferred at this event so you may want to note that there is a Desjardins ATM in the complex and Scotiabank, National Bank and TD ATMs a 12 minute walk south-west of the venue, behind the Grand Théâtre de Québec. And yes, this is a predominantly francophone event so it’ll give you a chance to brush up on your French. 🙂
Enjoy.
