HW Petrie was a machinist from Brantford. He joined a machinery business in 1882, and soon thereafter the firm was dealing in new and used machinery under his name, as well as in manufactured machinery. In 1915 the business relocated to Toronto, and focused on dealing machinery. Petrie took over the Doty Works building in 1919, applying a large painted sign to the familiar tower.

"H. W. Petrie & Co., Machinists and General Machine Dealers.—The senior member of this firm commenced business in Brantford, as a practical machinist, in 1877. Soon after this he began to buy and sell all classes of machinery, which the times and locality demanded. By thus combining the various features of a workshop with the commercial advantages of an exchange, he has succeeded in building up a flourishing addition to the many industries of the city.
In 1882 Mr. A. Petrie became associated with the original owner; since then the business has been conducted under the name and style of H. W. Petrie & Co. The shops contain the usual number and kind of sub-shops and labour-saving machinery, the power for which is supplied by a steam engine of ample size. From six to ten hands are employed, and a respectable amount of material consumed in the regular operations of the establishment."

Petrie's advertising typically highlighted a different, more striking building in Toronto: the Petrie Cyclorama building on the south side of Front, just west of York.

The Cyclorama building was torn down in 1970s. Used for pseudo-cinema shows in late 1880s before actual cinema, it was later used by HW Petrie Machinery, who eventually converted it into a parking garage for $125,000.
However, visitors were also welcome to visit the warehouse at Bathurst and Niagara, which Petrie took over in 1919.

Petrie would operate from this location for the next two decades, until 1940. The lot would be shared with several other tenants, including the Diamond Calk & Horseshoe Company, Mussens Machinery Ltd, and Holman Machines.
Diamond Calk & Horseshoe Company

As its name implies, the company's business was in the manufacture of insertable and removable calks (extensions on the toes or heels of horseshoes, for better traction), drop-forged horseshoes, and other farrier products. The business was based out of Duluth, Minnesota, and once had employed 800 people.

In 1931, Swanstrom patented a 'hooked' horseshoe that was designed to better catch a target post. This design innovation was a success, and the design was widely imitated. Diamond correspondingly grew in stature until it was a common name in the sport, and dedicated collectors will invariably come across Diamond shoes.

From 1924 to the 1940s, Diamond also operated a subsidiary manufacturing plant in Toronto -- in the Doty Works complex.

Diamond horseshoes are commonly marked 'Duluth', denoting their place of manufacture. Those produced in Toronto are rather less plentiful, and bear a unique 'Toronto' mint mark -- and those manufactured in Toronto in the 1920s and early 30s are further distinguished from most Diamond pitching horseshoes in that they are hookless, pre-dating Swanstrom's 1932 hook design.

The more I delved into the history of Front and Bathurst, the more I realized I was only scratching the surface of what has taken place at this corner.

My interests lie primarily around the Victorian era, so I did not pursue the tenancy of the Doty Works building past Diamond Calk and Horseshoe. That task is left as an exercise to the reader...

Fortuitously for the Toronto climbing community, the building managed to survive another fifty years, when a young entrepreneur named Karen McGilvray looked at the place and thought, "I could build a gym here…"
