All of the things you mention are included in the CPI. You don't know what you are talking about. The initial core inflation measure used by the Bank of Canada as an operational guide, CPIXFET, excluded food, energy and changes in indirect taxes. But it was replaced by CPIX in May 2001, which doesn't exclude most food categories, nor does it exclude electricity. Due to the incompetence of Finance Minister Bill Morneau and Governor Poloz it has in turn been replaced by three other measures, none of which exclude all food and energy. They all exclude changes in indirect taxes, as they should.
