Advanced polling starts again Wednesday â€“ less than a week away from the May 9 provincial election. During the first two days of advanced voting on Saturday and Sunday, more than 230,000 people cast their ballot. Thatâ€™s about 13 per cent of the 3.1 million registered voters, according to Elections BC statistics. Advanced voting is Wednesday, May 3 through Saturday, May 6. While voting locations are open from 8 a.m. to 8 p.m., not all locations are open every day of the advance voting period.
