​For 31 seasons, 4th Line Theatre has been bringing history to life on the barnyard stages of a rustic 5th generation farm in Millbrook Ontario, between Peterborough and Port Hope.  Founded in 1992 by Robert Winslow, this outdoor theatre company is committed to preserving our Canadian cultural heritage through the development and presentation of environmentally-staged historical drama. 4th Line has developed and presented 42 original plays based on regional history and culture. ​

In 2014, Winslow’s long time collaborator Kim Blackwell took on the role of Managing Artistic Director as Winslow transitioned out of his position as Artistic 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. “These productions,” says Blackwell, “celebrate the history of the area; they are stories with national echoes.”​

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.​

4th Line Theatre is a not-for-profit, cultural, charitable organization that heavily relies on monetary donations, ticket sales, government funding, advertising and sponsorship support to ensure our success year after year.
