Tone Performance Communications Incorporated was founded in 1986 by its president, Mr. Francis Sung. When AT&T entered the Canadian marketplace in the early eighties, Francis recognized the strategic opportunities inherent in helping AT&T deploy its installations across the country. Employed at that time, Francis, as a true entrepreneur, ventured out on his own to take advantage of this opportunity. Eventually, Tone became a pioneer for AT&T roll-outs in Canada as one of the first dealers to sell and service AT&T SMB products such as PBX phone systems.

Today, Tone Performance Communications Inc. is a successful company with over 30 years of experience that services over one thousand five hundred small to Fortune 500 companies across the Canadian marketplace, including major retail organizations, manufacturers, and financial, educational, utilities, government, car dealerships, and media services.

Since its foundation in the telecommunications arena, Francis’ corporate mission for Tone Performance Communications Inc. is:

  1. To provide clients with state-of-the-art products and services;
  2. To supply and to ensure corporations and companies have a functioning system that acts as their life-line;
  3. To connect companies with top-notch cabling and phone systems through professionalism and competency in the field; and
  4. To ensure that 30 years of experience translates to work being done to perfection for clients;

Headquartered in Markham, Ontario, Tone Performance Communications Inc. focuses on providing customized communications systems that best suits each client’s business needs. The key to our success has been professionally designed installations achieved through the dedication and commitment of our staff to our clients. Client satisfaction is critical in the telecom market and Francis insists upon exceeding clients’ expectations.
