October is one of the busiest months of the year for Quebec's business community. Chambers of commerce restart their big luncheons, economic development agencies relaunch their cohorts and training sessions are back after the summer. Here is the October 2026 calendar of business events, each one checked individually, across our four regions: Montreal, the South Shore, Quebec City and Trois-Rivières.
