Idyllic, rural, and quintessentially Canadian, 4th Line Theatre presents Canadian plays written by and about Canadians, from small town stories to broad national sagas.

Founded in 1992 by Creative Director Robert Winslow, this outdoor theatre company is committed to preserving our Canadian cultural heritage through the development and presentation of environmentally-staged historical drama.

In 2014, Winslow’s long time collaborator Kim Blackwell took on the role of Managing Artistic Director as Winslow transitioned into the position of Creative Director. Blackwell has been instrumental in defining the 4th Line aesthetic and works tirelessly to give audiences one of the finest theatrical experiences in the country.

This magical theatre presents unforgettable outdoor, epic theatrical experiences. Thousands of visitors, young and old alike fall in love with our farm experience complete with picnics, birdsong and sunsets in the country. Create a truly unique experience with a picnic lunch, a performance and an overnight stay at a local country inn or bed and breakfast, for yourself or as a gift.

The award-winning company is a unique staple in the Canadian summer theatre circuit, presenting plays rooted in local history and inspired by the rural landscape upon which they are staged.
