Canada's inflation rate tumbled to two per cent in November as recession-ravaged businesses cut prices to keep customers coming, Statistics Canada reported Friday. The national consumer price index increase dropped to 2.0 per cent in the month compared with October's 2.6 per cent figure. November's reading represented an even larger drop compared with the September CPI of 3.4 per cent. "The slowdown in November was due primarily to gasoline prices, which were 14.4 per cent below November 2007 levels, and far offset increases for food and shelter items," said Statistics Canada in a press release announcing the November numbers.
