Some parents and teachers have voiced concerns since the provincial government announced on Wednesday that it was considering scrapping a limit on class sizes in kindergarten and Grades 1 to 3.

The caps were introduced by the Liberals in 2003.

For kindergarteners, the current limit is 29 students per class. For first, second and third graders, the classes are capped at 23 students. There are also averages that school boards have to adhere to.

Here is a look at how class sizes have shifted in the GTA, in the last 15 years, according to the ministry of education.
