It wasn't so long ago that the founders of Mobil Grain wore the very shoes of the producers they serve today. Following in the footsteps of their father, Lavern and Sheldon Affleck successfully farmed, processed, and marketed their crops. On the side, they developed and sold automation systems and color sorting technology to enhance crops.

After many years on the farm, the brothers decided to focus more on the processing and marketing aspect of the industry...and the idea of a transportable grain terminal was born. The design criterion was based around the plan to have flexibility to be able to easily adapt to the ever-changing face of agriculture. In 2005, Mobil Grain's first operation site was set up in Moose Jaw, Saskatchewan. A year later, making use of its transportability feature, Mobil Grain was relocated to Meyronne, Saskatchewan where they developed a great relationship with the Great Western Railway shortline. Both Sheldon and Lavern were impressed with the unexpected benefits of a private railcar operation.

In 2009, with the purchase of Last Mountain Railway (Saskatchewan's 10th Shortline Railway), Mobil Grain was moved to a location along the rail-line; small-town Bethune, Saskatchewan. A little further down, at Chamberlain, SK, its truck unloading facility was built. Mobil Grain continues to offer innovation and competition to the industry.
