The company actually started as a foundry ror what was frequently called a “novelty works” under the name of the Brockville Novelty Works. It was formed in 1854 by James Smart shortly after he relocated from Scotland. Within a relatively short period the company was renamed the James Smart Manufacturing Company. The company continued to grow quite rapidly necessitating the addition of partners so more capital could be obtained. That resulted in the incorporation of the company in 1881. Over the next three decades four smaller companies were purchased and combined with the parent company.
Included in the acquisition of the smaller companies was the Gardiner Tool Co. of Montreal. Gardiner was a forging company that used the trade mark Diamond G. Amongst their products were a line of axes that commanded the highest acclaim. Many of the axes produced after Smart took over the company continued to bear the Diamond G brand, sometimes alone but also in conjunction with the name JAMES SMART or SMART'S. At least two dozen stampings are known that appeared on axes made in the Gardiner plant. Some were marketed with additional paper labels and some were marketed with only stampings.
Specialties manufactured by the James Smart Mfg. Co. involved the casting of iron and steel into a wide variety of products from furnaces and stoves to pots and pans used for cooking. The company also made lawn mowers, shovels and the frames for certain types of furniture including the leg and seat framework for wooden desks. They also made axes and associated edge tools as well as hammers.
The company provided goods for the domestic market as well as export goods.
In 1912 the majority of shares were sold to Canada Foundries and Forgings but the operation continued in the James Smart plant as the both James Smart and Canadian Foundries and & Forgings. The plant continued to be used until 1965. Some accounts indicate the date was 1967 but that may have applied to the legal ownership as actual manufacturing at the Smart plant was last conducted in 1965.
