About Us

A Brief History of Our Company.

Johnston’s was founded in 1986 by our president Allan Johnston. It began as a humble one man operation and has grown over three decades to include offices in Welwyn, SK and Calgary, AB. Today these two offices employ brokers that handle grain, chemical sales, and the logistic services that drive our retail business. Allan and his wife Judi manage the Welwyn office while Allan’s son Chevy and long time employee Joel Merkosky manage operations in Calgary.
