OTTAWA – Here we go again. The Bank of Canada will raise its benchmark interest rate by 0.75% on Wednesday: a new increase, therefore, after the 0.50% increase on June 1, when the rate was raised to 1.50. %. From Wednesday, it will be at 2.25%. The reason, as always, is that of the “fight against inflation” which in recent weeks has reached its highest level in almost 40 years: 7.7 per cent.
