First, if you treat each issue discretely, I think it is reasonable that you can have a discussion about these issues.
What I'm taking issue with, and what I think those who work in the grocery industry take issue with, is the deliberate characterization of grocers by a number of political leaders as being responsible for food inflation when all of the evidence is that this is not the case. Expert bodies, including the Bank of Canada and Statistics Canada, have been very clear with commentators. Notwithstanding that, they have made repeated attempts to link grocery operations, grocery business decisions and grocery profits to food inflation, when that is a spurious connection.
