Time is running out for voters in the southwest riding of Calgary-Lougheed to cast their advance ballots in the upcoming byelection later this month.

UCP leader Jason Kenney is running for his seat in the legislature after longtime MLA Dave Rodney stepped down in November.

The leader of the Liberal Party, David Khan, is also running in the byelection alongside four other candidates.

A candidate forum is scheduled at 2:00 p.m. on Sunday at the Braeside Community Centre.

The advance polls close at 8:00 p.m. and Election Day is on December 14.
