MONTREAL -- NDP Leader Tom Mulcair says Canadians will eventually tire of what he calls the Trudeau government's lack of substance.
The party has several challenges to overcome, including declines in poll numbers, membership and financing.
But Mulcair promises the NDP will continue to challenge the Liberals and hold them to account.
Mulcair was attending a party caucus meeting in Montreal that ended today.
Many party members are hoping an upcoming leadership race will boost the NDP's popularity.
There are no official candidates with the vote more than a year away, although several members have expressed interest in the job.
