Osmow's began in Streetsville, Ontario, in 2001 after Sam Osmow transformed a struggling sub shop into a shawarma-focused restaurant. The company built a menu around modern Mediterranean and Middle Eastern cuisine, including shawarma wraps, signature creations, salads, sides, catering, and other quick-service offerings. Osmow's has since grown into a wide North American restaurant network and continues to serve customers through dine-in, takeout, delivery, and franchising. Company materials also show a business that stays rooted in family ownership while extending a familiar shawarma brand across Canada and the United States.
