Elections BC is urging anyone in the province who has yet to cast their ballot in the proportional representation referendum to do so soon — and in person.

The deadline for Elections BC to receive the ballots is Friday, Dec. 7 at 4:30 p.m. PT — which means it's now too late to pop them in the mail, according to spokesperson Rebecca Penz.
