Few small-town theatres can claim to have changed a province’s culture, but the Gravenhurst Opera House can: it is credited as the birthplace of summer theatre in Ontario. Opened on March 12, 1901 — and celebrating its 125th anniversary in 2026 — the red-brick hall with its twin towers and steeply pitched roof was built as a combined Town Hall and Opera House after the old town hall burned in 1897. Designed by Toronto architect J. Francis Brown for about $12,000 and championed by Mayor Charles Mickle, it was dubbed “Mickle’s Folly” by doubters. History prefers “Mickle’s Vision.”
Inside, 305 seats in 19 rows sit beneath a noted wood ceiling, in a hall that is fully accessible and still busy year-round: professional theatre, concerts, tribute shows, stand-up comedy and film screenings, more than 100 performances a year, with over six million visitors through its doors to date.
Twice the town itself saved it — voting down demolition by a two-thirds majority in 1967, then fundraising for major renovations in 1993. The Opera House endures because Gravenhurst refused to let it go: a working piece of 1901, cherished, renovated and still taking a bow on the main street.
