Ontario Improv

The venue's events page lists this event, but may not be current.

The venue's own shows page did not mention an open mic on Aug 31, 2026 [s2]. It showed the same on Sep 1, 2026 [s3]. On Sep 5, 2026, a made-up address on the same site showed nearly identical content, so that silence cannot be trusted to reflect what is really on the page [s4]. Sign-ups are by an emailed audio or video clip, not a walk-in list, so whether this counts as an open mic is unresolved.
