NDP Leader Tom Mulcair is brushing aside premiersā€™ concerns about some his key election promises, including Senate abolishment, the partyā€™s child-care plan and his commitment to balance the books.

Speaking to CTVā€™s Question Period, Mulcair dismissed criticism from Ontario Premier Kathleen Wynne, who recently mocked his suggestion that a federal deficit could be eliminated by getting rid of the Senate.

ā€œWell Iā€™m looking forward to working with Premier Wynne, of course, after the election,ā€ said Mulcair.

The NDP leader has long promised to abolish the Red Chamber if elected. His plan, however, canā€™t be executed without the support of the provinces.

And . Wynne has said the plan is unrealistic, while Quebec Premier Philippe Couillard has said abolition would not be in his provinceā€™s interest.

. The plan would require the provinces to pay for 40 per cent of the massive program.

So far, only Manitoba has expressed support for the NDPā€™s daycare plan. But Mulcair is hopeful that he will convince the other provinces once he meets with them. For example, he pointed to potential negotiations with Ontario.

ā€œWe havenā€™t sat down with them yet,ā€ said Mulcair. ā€œAnd Iā€™ve always used the Ontario example ā€¦ We would take into account the fact that Ontario has two full years of paid kindergarten. That would be part of our analysis when we sit down with them.ā€

Mulcair will reveal the full costing of his platform on Wednesday, one day before the second federal leadersā€™ debate. He also said on Question Period that he will focus on his partyā€™s health-care promises next week, including seniors care, the cost of drugs and mental health.

ā€œThere are things that are being left by the wayside and there are demographic changes that are going to call upon us to look at things differently.ā€
