A second generation of New Brunswick’s McCain clan has rekindled a long-standing family feud over a multibillion-dollar fortune.

Thirty-one years after brothers Wallace and Harrison McCain fought for control of McCain Foods Ltd. – a battle for the world’s largest French fry maker that Harrison won – Wallace’s daughter, Eleanor McCain, has kicked off a showdown with her relatives by demanding they buy her out of one of the country’s largest privately owned companies.

Eleanor, a 56-year-old musician who lives in Toronto, recently triggered an agreement that she says requires her siblings, cousins and their offspring to purchase her stake in the holding company that owns McCain Foods.

Based on the value of comparable publicly traded food companies, McCain Foods is worth at least $20-billion and Eleanor’s investment could be worth more than $1-billion.
