Starting on Monday, New Democrats can make their choice on who should replace Tom Mulcair as leader of the federal party. A weekend caucus retreat in Hamilton, Ontario saw the four leadership hopefuls make their final appeal to members. Ontario legislature member Jagmeet Singh, Ontario M-P Charlie Angus, Manitoba M-P Niki Ashton and Quebec M-P Guy Caron each presented their plan for the federal party. The new leader will be named in October.
