The chain Fisher volume estimates, which StatCan misleadingly calls chained 2007 dollars estimates, show a lower growth rate at 2.3%; the corresponding inflation rate based on a chain Fisher price index would be 1.5%, since the increase in the value of exports was 3.8%. One would really be an optimist to see a trend in this single month of solid export growth, with a trade war with the US likely to break out in the current quarter.
