The stage is situated on a small island, and spectators sit on the surrounding hillsides on lawn chairs or blankets. Hundreds attend outdoor performances there each summer. An annual performance of a religious play (entitled: The Promise), acted in by members of the town, was held annually from 1995 until 2005. In 2006 a play entitled "Their Finest Hour" was performed, and since 2007 country music concerts entitled "Music In the Valley" have been held there.
Forest is situated on what was once dense forest. When the Grand Trunk Railway was built through where the town now sits, the station was named for the dense forest. Hickory Creek, which meanders through the town, provided water for the station in those days when wood and water were essential to the operation of steam locomotives.
The first post office, in 1859, was then named Forest. The site was very near the junction of three township boundaries, with parts of Warwick, Plympton and Bosanquet townships all annexed into the town. None of these townships remain as political units due to amalgamation, with Bosanquet joining Forest in forming Lambton Shores (along with the villages of Arkona, Thedford, and Grand Bend).
The industry of the town was initially tied to the abundant fruit growing operation ... there was once a canning factory and a basket factory in Forest. In more recent years the town has become a dormitory community for the city of Sarnia (and to a lesser extent London, Ontario). Support to the extensive tourism area along the shores of nearby Lake Huron also supports several businesses. Several small factories supporting the auto industry have also opened in the past few years.
Forest was the birthplace of John L. McPherson, missionary and General Secretary of the Hong Kong YMCA from 1905 to 1935.
Donna J. Scott is an important member of the Forest community and currently resides in Waterloo, ON.
