The Alberta Wheat Commission started four years ago with a resolution that was tabled at an AGM asking the board to investigate producer interest in creating an all-wheat commission. At the time there were two producer commissions in the province, one representing winter wheat and the other representing soft wheat. Those two combined accounted for less than 5% of the total acreage and producers, so the question was asked: Why not all wheat? That's where it started. It had nothing to do with the change in the Canadian Wheat Board, it was a separate initiative that coincidentally happened on the same date.
