Yorkville Sound is a privately owned Canadian Company located in Pickering, Ontario, Canada, a suburb of Toronto. With over 200 people employed, Yorkville designs and manufactures all of its North American built products at the 150,000 square foot Pickering facility. Yorkville Sound manufactures a full line of professional PA products including mixers, amplifiers, active and passive loudspeaker cabinets and portable lighting rigs.

Founded in the back room of the original Long & McQuade Music store in downtown Toronto in 1963, co-founder Peter Traynor, a repairman at the time, developed a bass guitar amplifier dubbed the "Traynor Dyna-Bass" as a rugged and reliable alternative to amps currently available at the time. The Dyna-Bass amp was specifically designed and built to withstand the rigors of rentals and the road. Shortly thereafter, he and Jack Long officially started Yorkville Sound, and by the end of 1963 Yorkville was making P/A column speakers as well as bass amps and cabinets. After incorporating in 1965, Yorkville Sound expanded its sales into the USA and soon after added a guitar amplifier (the YGA-1) and a powered P/A mixer (the YVM-1) to the line. Throughout the 1960's Yorkville continued to grow and become a serious force in North America for P/A and instrument amplification products.
