OTTAWA, Feb 22 (Reuters) - Two of three core measures of Canadian inflation watched closely by the Bank of Canada were revised upward on Monday, as Statistics Canada reversed methodological changes made ahead of its last release that made the January data appear weaker. The changes did not impact Canada's headline inflation numbers, which showed a larger than expected acceleration in January. "Following feedback from users, Statistics Canada has determined that these changes require further evaluation and analysis," the agency said in a statement.
