This seems to have wrong-footed the Bank of Canada, which only identified “stronger real GDP growth in the US” as a risk to the inflation outlook in its October Monetary Policy Report. It speaks about stronger export growth but ignores completely the threat coming from a faster than expected rise in interest rates in the US (the US Fed now seems to have pencilled in three interest rate hikes in 2017 rather than two). If the Bank of Canada does not respond to the US Fed’s interest rate hikes, and it has so far not shown any inclination to do so, the loonie is bound to continue to drop, raising the inflation rate. 
Despite what Chair Yellen said, the US Fed seems to be targeting de facto a lower inflation rate than 2.0%. The Bank of Canada should do likewise.
