British Columbia's election agency says it has discovered that a ballot box containing 861 votes wasn't counted in the recent provincial election, as well as other mistakes, including 14 votes going unreported in a crucial riding narrowly won by the NDP.
The errors prompted B.C. Conservative Leader John Rustad to call for an independent review on Monday.
Elections BC said in a statement that the omission of the ballot box did not affect the result in Prince George-Mackenzie, the electoral district where the box was found.
It said the unreported votes in Surrey-Guildford were discovered last week during preparations for a judicial recount in the riding, where Garry Begg's 27-vote victory propelled the New Democrats to a one-seat majority government.
Rustad called the errors "an unprecedented failure by the very institution responsible for ensuring the fairness and accuracy of our elections."
"While I am not disputing the final outcome pending remaining judicial recounts, it's clear that mistakes like these severely undermine public trust in our electoral process," he said.
B.C.'s chief electoral officer, Anton Boegman, said in the statement that the discovery of the "anomaly" in the Surrey-Guildford count triggered a provincewide review.
"Our elections rely on the work of over 17,000 election officials from communities across the province. Unfortunately, unintentional human errors do occur in administering the vote," he said.
The review, which started last Wednesday and ended Sunday, identified what the statement described as "data entry omissions" that resulted in mistakes impacting "a small number of votes" in 69 of the province's 93 ridings.
It said the omissions "comprise only 0.05 per cent of total votes in those districts."
The mistake resulted in 14 votes for Surrey-Guildford not being counted, it said.
The recounts in the province's Supreme Court for that riding and Kelowna Centre are scheduled to take place on Nov. 7 and Nov. 8.
In British Columbia, voters can cast a ballot for their riding at polling stations across the province.
The statement said election officials in six ridings erred by not reporting out-of-district results that had been recorded on 11 tabulator tapes.
The statement said the number of unreported votes in each district did not affect the outcome in any of them, pending judicial recounts in the two ridings that had been triggered by their narrow margins.
Boegman said the errors were disclosed to the judges and parties involved in the recounts and added that election officials "were continuing our review to ensure that any additional omissions were identified."
The statement said a recount of the ballot box in Prince George-Mackenzie, a riding easily won by B.C. Conservative Kiel Giddens, had been requested.
It did not explain how the ballot box was missed on the election day count.
Elections BC did not immediately respond to a request for more details.
Pending the judicial recounts, Premier David Eby's NDP have 47 seats in the legislature, the slimmest possible margin to form a majority government in British Columbia.
