I don't know about Ontario, but here People can skate by.
I used to tutor. Quite a lot of kids missed something simple somewhere in the beginning and then were skating by having passable but not good grades. Not understanding what is taught, but getting enough points.
The tutoring consisted of going beck few years and teaching them basics again. They improved, but school never did that "maybe this person now can learn the thing he/she missed 3 years ago".
