The 1.3% decline in electricity prices is a political decrease to save the Ontario Liberal government and only masks inflationary pressures that will inevitably manifest themselves no later than a year from now, following the Ontario general election. With a core inflation measure based on the exclusion principle, like CPIX, it was easy to exclude another component like electricity for a limited time if circumstances seemed to warrant it. It would be problematic to do something like this for the three new core measures, since they aren’t exclusion-based. And of course, even if one accepts the CPI excluding mortgage interest costs as conceptually a good indicator, because only new housing price data is used in the CPI, the current surge in housing prices is badly underestimated.
