OTTAWA -- Prime Minister Stephen Harper has announced that three federal byelections will be held on Nov. 26.

The votes will be held in the ridings of Victoria, Calgary-Centre and the Ontario riding of Durham.

The ridings became vacant when members resigned.

Former cabinet minister Bev Oda quit following controversy over her expenses, including an infamous $16 glass of orange juice, leaving the Durham riding vacant.

New Democrat Denise Savoie resigned her Victoria seat for health reasons.

Conservative Lee Richardson left in Calgary-Centre to work for Alberta Premier Alison Redford.
