Manitoba's rookie Liberal leader says when the time is right, she will explain how she plans to pay for tens of millions of dollars in promises she is making in advance of next April's provincial election.

Some of her recent promises include a 25-million-dollar sales tax rebate for municipalities, and 10 million dollars a day to convert student loans to grants.

She is also promising up to five million dollars a year for increased in vitro fertilization funding and a phased-in elimination of the payroll tax
