N.Y. Elec. Law § 9-206
The canvassing board shall canvass the votes cast within the county for state, county, city and town offices; also the vote cast on any ballot proposal. The canvass by the county board of canvassers relating to the offices of president and vice president of the United States, governor, lieutenant-governor, state comptroller, attorney-general, United States senator, member of the house of representatives, member of the state senate, member of the assembly and any ballot proposal shall show in each election district the total number of persons voting at such election, the number of votes cast for each candidate, the number of unrecorded or blank votes for each of the above-mentioned offices and each ballot proposal. Write-in votes cast for president or vice president for persons who were not certified by the state board of elections as write-in candidates for such offices shall not be canvassed for such candidates but such votes shall be canvassed as void votes. If, during the canvass, there shall clearly appear to be any omission or clerical mistake in the return for any district filed with the board of elections, the canvassing board may summon the election officers before the board, and such officers shall meet forthwith and make any necessary correction, in order that their canvass may be correctly stated, but they shall not alter any decision theretofore made by them.
