Part of the problem in Canada is that the price per kilogram is usually present in small print, while the price per pound is very predominant. Allowing the price per pound to be advertised will only slow any transition, as people are generally creatures of habit and will continue to migrate to what they are familiar with. In order to make them familiar with metric they need to use it. If the price per pound continues to be displayed, many Canadians will train their minds to ignore the price per kg, much the same as English speaking Canadians ignore the French labelling on packages.
