CANADA GDP RISES 3.1 PCT IN 1986 Canada's real gross domestic product, seasonally adjusted, rose 1.1 pct in the fourth quarter of 1986, the same as the growth as in the previous quarter, Statistics Canada said. That left growth for the full year at 3.1 pct, which is down from 1985's four pct increase. The rise was also slightly below the 3.3 pct growth rate Finance Minister Michael Wilson predicted for 1986 in February's budget. He also forecast GDP would rise 2.8 pct in 1987. Statistics Canada said final domestic demand rose 0.6 pct in the final three months of the year after a 1.0 pct gain in the third quarter. Business investment in plant and equipment rose 0.8 pct in the fourth quarter, partly reversing the cumulative drop of 5.8 pct in the two previous quarters.
