The Ford Government is eliminating free tuition for students from low-income families while also cutting tuition fees.
The Tories say OSAP grants have become unsustainable and it's time to refocus and provide help to students in the most financial need.
The previous Liberal government increased the number of grants and made it possible for low-income students to attend college or university free of cost.
But the auditor general found last month that costs for that program jumped by 25 percent and warned it could grow to $2 billion annually by 2021.
The province has announced that family income thresholds for the grant would be lowered and instead provide more loans.
Most of the of grants will go to students whose families have an income of less than $50,000, but the government didn't identify the cut-off for a grant.
Under the new framework, tuition will decrease by 10 percent for the 2019-2020 year, then be frozen for the following year.
