BOC Governor Macklem said new US tariffs could push Canada's Q4 economic growth below 1%. He warned slower growth would weigh on inflation while Middle East conflict-driven oil gains could lift it; annual inflation is about 3% versus the BOC's 2% target. Macklem said if oil stays near $100/bbl, inflation could rise modestly.

He added that if the new tariffs persist, Q4 growth could be roughly halved to under 1%.
