Mugsi -> My Profile -> Social Insurance Number

or easier would be:

McMaster University Portal -> My SIN

Thanks, but when I put it in it says "you did not change, please re-enter"

I'm not sure then, try contacting the office of the registrar;

If it says you did not change, then maybe your SIN # was already on there?

Lol, I make that mistake too. I blame it on abbreviations, always mixing people up XD

Unless your sin number has changed, it was most likely already on your account/record. That was the case for me at least.

Hmm, that's weird/lucky . I had to do it myself . but maybe for people with OSAP it's already on there, since you actually enter it on your OSAP application

Interesting. I do have OSAP so that makes a lot of sense! Learning something new every day
