Аннотация:abstract A formal analysis of the amending formula of Canada's Constitution Act, 1982 is presented. It is shown that larger provinces have greater voices in determining constitutional amendments, except that there are two groupings of provinces within which power with respect to constitutional amendments is exactly equal. Further, it is argued that differences in power among the provinces are disproportionately small in comparison to differences in population, so that the amending formula systematically directs greater influence to the individual citizens of smaller provinces.
