The CST-Arwin Story

CST-Arwin was formed with a vision to provide the dynamic and growing electronics marketplace in Canada with quality products from a select group of component manufacturers. CST-Arwin was started in 1992 as a small regional rep firm called CMI serving the Montreal, Toronto, and Ottawa marketplaces. In the late 1990s CMI merged with Southall Thomas Inc., another small regional rep firm serving the same markets. One year later, they all merged with Arwin Technical Sales, based solely in Western Canada and became CST-Arwin Inc. The new company provides cross-Canada coverage with offices in the primary cities in Canada. Their focus is a passive electro-mechanical product with an emphasis on excellent customer service and technical support.

We have representatives to help you in our 3 offices: Central Canada (Toronto Region), Eastern Canada (Montreal/Ottawa/East Region), and Western Canada (B.C./Alberta/Prairies Region).
