Inflation rose to 4.4% in September, beating the average analyst estimate of 4.3%, to reach its fastest clip since February 2003, Statistics Canada data showed. CPI common, which the Bank of Canada calls the best gauge of the economy's underperformance, was flat at 1.8%, while the other two measures of core inflation posted gains. Governor Tiff Macklem warned last week that supply chain bottlenecks mean it will probably take a bit longer than previously expected for inflation to come down.
