> The whole operation is overseen by the Ontario Food Terminal Board.. $8 million of expenses... with a revenue rate exceeding that by $1 million, the operation is profitable, self-sustaining and receives no government support or preferential treatment despite its status as an agency of the Ontario Ministry of Agriculture, Food and Rural Affairs.. Some of those that operate here are among the wealthiest families in Canada.. The thirty-year leases held by the most powerful grocers in the city are renewable in perpetuity, privileging a small number of family-owned businesses that have kept a tight hold on their terminal rights for over three generations. The business is so robust, and the leases are so sought after, that each one is estimated to be worth over a million dollars in annual economic returns.
