CANADA MANUFACTURING UTILIZATION RATE RISES Utilization of Canadian manufacturing capacity rose to 77.2 pct in the fourth quarter of 1986 from 77 pct in the third quarter, Statistics Canada said. "Although the change was small, this marked the first quarter since the third quarter of 1985 in which the utilization rates for manufacturing as a whole rose," the federal agency said. Increased residential construction led to strong increases in the building materials sector, led by a 3.3 pct increase in non-metallic mineral industries.
