Buffalo has six principle locations of business providing a full spectrum of inspection services. These locations are Edmonton (Corporate Office), Grande Prairie AB, Red Deer AB, Whitecourt AB, Fort St. John BC, Kelowna BC, and Estevan SK.

Witness was founded out of a need to supply defect-free products both efficiently and cost-effectively. Our state-of-the-art inspection systems led to greater accuracy and repeatability, expanding our services beyond human operators. Over 20 years later, Witness remains a strategic partner in the industrial supply process.
