The market was founded by Bob Stiver, a descendant of the Stiver brothers. The Stiver family has resided in Unionville and Markham since 1794 as part of the wave of migrants brought over by William Berczy. The market is located next to the historic Stiver Mill, a grain mill built in 1916 (as well as structures moved from Matthew Grain Company of Toronto) for Charles and Francis Stiver and operated as Stiver Brothers until 1968. Besides grains (as well as seed and feed), the business sold cement, coal and salt. The site was acquired by the then Town of Markham in 1993 and closed from 2013 to 2014 when the mills structure was restored.
