History

Located at the centre of the GTA, the Heintzman House is one of the oldest buildings in the region with a long and fascinating history; home to many of Thornhill and Markham's leading citizens.

Built as a respite from city life, this country mansion is an eclectic blend of Classic, Georgian and Regency style architecture with a Classical Revival porch featuring magnificent portico pillars. Both the picturesque gardens and the house have been exceptionally maintained and lovingly cared for.

The House, which today has over thirty rooms including a grand ballroom and solarium, began as a modest two-room adobe farmhouse (the earliest on record in the province) constructed by Loyalist Anthony Hollingshead between 1797 and 1802. In 1816, Col. George William Cruickshank, a veteran of the Napoleonic Wars and the area's first justice of the peace, built a thirteen-room mansion around the original farmhouse and named it "Sunnyside Manor".

Between 1854 and 1930 the House was owned by a number of families before it was purchased by Charles Heintzman, of the Toronto piano company. In 1959, the House was purchased from the Heintzman estate by developers. In 1967, the (former) Town of Markham stepped in to save the building after a group of concerned citizens successfully campaigned for the Town to purchase the property for posterity.

Today, a Board of Directors appointed by the City of Markham manages the Heintzman House. The House is rented by local organizations, used for business meetings, has been used in commercial and film work, and is a popular venue for wedding parties and receptions.

Exuding the charm and grace
of bygone days, this historic
house will provide you with
the perfect setting for a
truly memorable occasion.
