The B.C. Lottery Corp. said the winning ticket will expire at midnight on March 18, exactly a year after the draw. Erica Simpson, a spokeswoman for the lottery corporation, said Thursday it’s rare for major jackpots to go unclaimed. Over the past 10 years, she said only six major prizes of $500,000 or more haven’t been claimed. It’s also uncommon for winners to wait until the last minute to cash in. “A year ago it was the start of the pandemic and a lot of things were changing … stores were closing and people had a lot on their minds,” Simpson said. “We want our players to think back on when they might have purchased tickets in that area.”
