Our History

Sight N Sound Design evolved from The Ken Lewis Group and Interface Controls in the year 2005. The original company Ken Lewis Group was formed 1978 in Western Canada at a time when the only well know audio visual consulting firms were based in the US. The firm expanded into Ontario with the assistance of a new partner who was based in Toronto.

Ken Lewis Group was a pioneer audio visual consulting firm which quickly became known right across Canada for its out of box thinking and technical audio visual capabilities. One of its first major projects was for Imperial Oil in creating a state of the art television studio and boardroom audio visual presentation system. This project led to the firm developing an automated presentation modular audio visual wall system that can be clad in many different finishes. This product greatly simplified the integration into presentation spaces of various different audio visual surfaces such as white boards, front and rear projection screens with cover sliding panels which hides everything away including video conferencing cameras and today more commonly flat screen technology when audio visual capabilities are not required in a presentation space. Read more about this here.


The Automated Presentation Wall System was granted a US and Canadian patten in 1991 and 1992. The firm also received the ICIA Crystal Achievement Award Manufacture of the Year award in the US.

Thru its activities in manufacturing Interface Controls was the first control system company to deploy Point and Click system programming in the audio visual world.


The firm is proud to have been the recipient a number of times of the Toronto Construction Association Best of the Best Awards together with ARIDO award of Recognition.

The company was founded by Ken and Pat Lewis as a traditional family business. In 2005 their son Martin Lewis became a partner in the firm and the name Sight N Sound was born.

Sight N Sound Design has a long history in leading the way constantly creating new audio visual deployment methods.
