It seems to be a fairy-tale ending for what was once a grim story about prime Ontario farmland. Months ago, the Highland Companies, backed by Boston-based hedge fund, had bought some 6,500 acres of prime Ontario farmland and planned to turn it into a giant rock quarry. But faced with staunch opposition, the company withdrew its proposal. Now the company has sold the land it bought for the quarry to Bonnefield Financial, a Canadian group dedicated to preserving the land for farming - in perpetuity. Tom Eisenhauer is the president of Bonnefield Financial. We reached him in Toronto.
