Thompson Potato Farm is proudly owned and operated by 5th and 6th generation Canadian farmers. We have specialized in growing potatoes since 1943. Our quality potatoes are packed and delivered year round to restaurants, grocery stores, and wholesale companies in the GTA. Sweet corn is picked fresh daily during the summer to complement our ever ready supply of potatoes for sale at the door. We are nestled in the hamlet of Holt, which is located northeast of Newmarket just minutes from the 404.
