Canada’s Lakeside Packers is to increase capacity at its Canadian plant in an effort to reduce the oversupply of cattle. The chief executive of Tyson Foods, which owns Lakeside, announced that the Alberta plant plans to begin increasing its beef slaughter capacity in mid-June. The change is the result of a $17 million plant expansion project, which has been underway since last autumn. The Lakeside plant has been operating at maximum capacity for much of the past year and a half because of record-large Canadian cattle supplies.
