The "official canvass" is the public process of processing and tallying all ballots received in an election, including, but not limited to, provisional ballots and vote by mail ballots not included in the semifinal official canvass. The official canvass also includes the process of reconciling ballots, attempting to prohibit duplicate voting by vote by mail and provisional voters, and performance of the manual tally of 1 percent of all precincts.
