Ontario NDP Leader Andrea Horwath wouldn't provide details today of what families earning more than $40,000 would pay for child care under her plan for the province.

The NDP is proposing to fully subsidize public, licensed, not-for-profit child care for those lower-income earners if elected next month.

Households earning more than $40,000 would pay an average of $12 a day, but the NDP has not given details about brackets, specific fees or caps.

Horwath was asked several times for those details today, and would only say that it is a sliding scale.

She says the highest-income families in the province will not see a huge break, but families who are struggling to pay their rent and hydro bills need help.

The NDP child-care plan also proposes to increase wages for early childhood educators and add 202,000 new not-for-profit, licensed, affordable child-care spaces.
