 The purpose of the jury award is to ensure that albums which were artistically important, but not necessarily as commercially popular, still have a fair shot at being selected as winners; to ensure that two different albums are selected, however, the jury does not meet to vote on its choice until after the popular vote winner has been determined.Between 2015-18, non-winning nominees in a Heritage Prize category were renominated again, reincorporating all of the non-winning nominees from the previous year, with only the winning albums replaced by new titles.In 2019 Polaris chose to do away with the four time period format, reducing the total number of nominated albums from 40 to 12 and putting those 12 albums in one single category with no separation by time period.
