The Waldie Blacksmith Shop is a post and beam timber structure with rubble stone infill wall. It is rare that a blacksmith shop structure still exists in its original urban location as most shops have been lost or moved to a museum setting. The building has been lovingly preserved and restored on its original site over the past 3 years under the auspices of the Milton Historical Society.

James Alfred Waldie was born in Scotland in 1832. He completed his apprenticeship as a blacksmith in Scotland by 1853 and as a young man came to Canada eventually taking over a blacksmith business in Acton. By 1865 the Waldie family had moved to Milton establishing a blacksmith business that would operate in the same building at 16 James Street for over 100 years.
The blacksmith shop, built by James Waldie Sr., employed a painter, trimmer, two woodworkers and five blacksmiths from dawn to dusk during its peak period in the early 1890's. Three generations of Waldies: James Sr. (1832-1900), James Jr. (1871-1948) and Alfred (1905-1980), shoed horses, repaired wagons and manufactured farm implements and horse drawn carriages for the local community. Alfred was the last member of the Waldie family to operate the blacksmith shop which he closed in the early 1970's. His dream to have the blacksmith shop restored is now a reality thanks to the efforts of the Waldie family, Milton Historical Society, Town of Milton, Province of Ontario, and the community.
Restoration of the Waldie Blacksmith Shop preserves an important link to one of the earliest—and most vital—businesses in the history of Ontario. The blacksmith's role was crucial in keeping horses, oxen and mules capable of tilling the soil, drawing wagons, sleds, and carriages both on the farm and in towns and villages.
