Heintzman House
Welcome to The Heintzman House - one of Markham’s most treasured historic landmarks
Originally built as an adobe brick cottage in the early 19th century, the home was expanded in 1817 by Colonel George Crookshank. In the 1930s, Charles T. Heintzman, grandson of the founder of Toronto’s Heintzman Piano Company, purchased the property and transformed it into the elegant residence you see today.
