The Canada and British Columbia pension funds have indicated they favour a deal, if and when emerges, for Bunge to purchase Viterra.
They are rumoured to be engaged in negotiations.
Viterra is the merger of the former Alberta, Saskatchewan and Manitoba wheat pools.
A merger would make Bunge the largest grain trader in North America, surpassing Cargill and Archer Daniel Midlands. However, Cargill and ADM would still be larger on a global scale.
