Does anyone know if your OSAP is significantly affected if you do workstudy during the term for 8-10 hours a week?

My OSAP was not affected much (maybe not at all) and I think there is a rule where you are allowed to make up to about $110 a week without it affecting OSAP. I was limited to 10 hours a week probably because of that.

Edit: It talks about the limit in this link; its $103.

Not sure I can answer you after I talk to financial offices after school starts

It's actually whack that you can only make $110 a week before it affects OSAP. Tuition, rent and cost of living has risen, plus I'm overloading so I'm paying for six additional units, yet did I get more OSAP this year? Noooope. Aside from finding a cash job, I'm not sure what to do.

The work-study program is the limit that OSAP allows of work while studying full-time. You do have to keep them updated with your income though. I can't say if it'll affect it because it depends on so many things, your courseload, parents' income, program costs, and your income. Call them and they'll be able to give you more info about your specific situation.
