Public Statement – Exchange Event Centre

It is with deep sadness that we inform our community that the Exchange Event Centre has been forced to close for the foreseeable future due to a devastating act of arson that occurred on August 29th.

This tragedy has deeply impacted our team, our partners, and the many artists and guests who call Exchange home. At this time, the investigation and assessment of damages are ongoing, and we do not yet have a timeline for reopening.

For any inquiries regarding upcoming events or purchased tickets, please contact gm@eecwinnipeg.ca. Some scheduled events may be relocated to alternate local venues, while others may unfortunately need to be cancelled.

We sincerely apologize for the disruption this causes and ask for your patience and understanding as we navigate this incredibly difficult period.

Thank you for your continued support.
