Parkwood Estate, National historic estate in Oshawa, Canada

Parkwood Estate is a manor house with several dozen rooms in Oshawa and comprises a large residential building with period furnishings from the early 20th century. The property extends across a sprawling site with maintained lawns and garden areas surrounding the central building.

Construction of Parkwood began in 1916 to designs by the Toronto firm Darling and Pearson, and the McLaughlin family moved in in 1917, living there until 1972. In 1989 the federal government designated it a National Historic Site, and R.S. McLaughlin was named a National Historic Person the same year. The house opened to the public as a museum.

The residence displays elements of classical European manor design with formal garden sections featuring symmetrical beds and borders. Visitors can walk through these spaces and gain an impression of how wealthy Canadian industrial families lived.

Tours run year-round and cover the 55-room house and the gardens restored to their 1930s appearance. The grounds are divided by cedar hedges into garden rooms such as the Italian Garden, Sundial Garden and Sunken Garden, so allow time to walk the sequence of views. Three greenhouses are still in production and hold palms, orchids and tropical plants.

The outdoor grounds served as filming locations for movie productions and some interior rooms appeared in well-known cinema releases. The building facade and surrounding garden areas provide a backdrop that recalls English manor houses.
