It is anticipated by RBC that year-over-year headline CPI dropped to 1.8% in September from 2% in August, while the sub-index, which excludes the more volatile food and energy components, remained steady at 2.4%.

The growth of the gross domestic product (GDP) for Q3 appears likely to underperform, despite continued rapid population growth.
