Definition
Since 1991, the Bank of Canada and the federal government renew every 5 years an inflation-targeting agreement, currently at 2% ± 1 percentage point (range 1-3%). This objective guides all policy rate decisions.
The Consumer Price Index (CPI) is the primary measure. The BoC also monitors core inflation measures (CPI-median, CPI-trim) that exclude volatile components (energy, food) to detect underlying trends.
Direct mortgage impact: when inflation exceeds 3%, the BoC raises rates to slow the economy → higher variable rates and renewals. When inflation falls below 1%, the BoC cuts rates to stimulate → lower variable rates.
