So I have to go pick up my OSAP on August 24th, and I was wondering if it would be really busy and I would have to line up for a long time. Also one of the required pieces to bring was a void cheque/banking information and I was wondering what that is

It shouldn't be too busy when you go if you go early. I went around 11 am last year and I think I was there for about a half hour. As for the banking information, you just bring a cheque with void written on it or a direct deposit form from your bank for the account you want them to put the money into. Hopefully this helps a little.

It doesn't actually have to be void if you don't want to void a cheque (if you have to pay for cheques for example). I assume that in the past they used to take the cheques, but these days they just need the banking information which is found on the bottom of the cheques (it's all those numbers at the bottom). You just have to transcribe those to the documents you have to sign. I believe you can also just bring those numbers and not even have to bring a void cheque. You can also just go to your bank and ask for that information. It's the transit number, institution number, and account number.

Oh alright, thank you so much!
