Over 200 people are expected to take part in the Liberal Party's nomination meeting for the by-election.
The President of the Brandon-Souris Federal Liberal Association says the vote will take place at 7pm, next Wednesday.
Gerry Dyck says he's happy with both candidates.
Rolf Dinsdale is one, while Killarney Mayor Rick Pauls has not officially been named a candidate yet, but Dyck doesn't think there will be any issues.
The meeting will take place at the Royal Canadian Legion on 13th Street East.
Anyone wishing to vote needs to register by Monday at 5:00.
