He said the cuts will target some 9,600 "non-classroom personnel" considered expendable by the Drummond report, which examined Ontario government spending across the board.
"We've got to make some choices... but what do I want to see? What does our plan involve? Making sure that special education students get the best quality of education possible."
He said that with education spending up while there are less students in school it's time to take a close look at the system and programs such as full-day kindergarten, which was brought in by the Liberals and will be in every elementary school when classes start this fall.
"More money, fewer kids and our test scores have either plateaued or gone dangerously down in areas like mathematics," said Hudak.
"Some of these programs do have merit. But we're in a realm of not if a program is good or bad, it's what can we afford."
The Tory leader's platform calls for increasing class sizes, which could affect the number of public school teachers, and reducing the number of early childhood educators in full-day kindergarten classes.
Hudak said the steps are needed to balance the budget within two years.
The Liberals claim Hudak's plan would see upwards of 22,000 educational workers lose their jobs: 10,000 early childhood educators, another 10,000 support staff and "thousands" of teachers.
"The total cuts in education alone could total 30,000 jobs and $2 billion, once the extra cuts Hudak needs to balance the budget in 2016-17 are factored in," the party said in a news release.
In a video released Monday, the Elementary Teachers' Federation of Ontario — which had earlier feuded with the Liberals over a bill forcing a wage freeze — made a plea for the electorate to back anyone but Hudak in tight races.
"Every vote against the Hudak Conservatives will be a vote for education and for a better future in Ontario," President Sam Hammond says in the spot.
Ontario voters go to the polls on Thursday.
