M&M opened its first new franchise in nearby Cambridge, Ontario, in 1982. Mac's brother and co-owner, Greg Voisin, became director of franchising in the mid-1980s. Since then, it has expanded to over 425 stores across Canada. M&M entered Quebec in 1992 and in 1997, it entered the western provinces by acquiring the business of Jeffrey's Food, based in Edmonton, Alberta in 1993. M&M opened its first store in Yukon in 2004 (at Whitehorse) and in the Northwest Territories in 2006 (Yellowknife). Some of Mac's family members, including Guy Voisin, also work for the company.
