Six Decades of
Excellence

Owner and founder, John Maslack, had one vision for his life’s passion: to take the customer experience to a higher level. Maslack Supply has proudly served our communities with this model since 1959.

Our Story

Owner and founder John Maslack is known throughout the industry as a solution provider. He has spent his entire career working to provide his customers with ways to “get the job done". John has always believed that the customer should be the most important element of any business. It is with that vision and determination that Maslack Supply opened for business in 1959. 

John Maslack started the business with a 5,000 square foot facility on Barrydowne Road and with three employees. The Maslack group of companies has since grown to include 12 locations across Ontario, including a 70,000 square foot warehouse and training centre at its main branch on Falconbridge Road, and over 200 dedicated employees. Maslack Supply continues to grow with the same highly skilled, efficient, and customer-driven staff that have made it a landmark in the automotive, industrial, and refinishing sectors since its humble beginnings. 

Regardless of how far the company expands, John Maslack’s founding principles continue to be Maslack's bedrock for operations. Simply put: we serve the best – our customers.
