Bro sounds like you never attended tax clinics or whatever it is in your university.
Your reading weeks and everything is in records of the service canada and your university tells servicecanada about the reading weeks and then they approve and only after that you are allowed to work full time during that time.So thats out of questioning that the canadian government will not know about your breaks and holidays everything is kept in records.
Attend any tax clinics and you will know about this and also T4 which is statement of remuneration and T4A i.e statement of other income.
My advice dont ever ever take even slightest of risk, after spending all the money ,staying away from parents, working shifts all for just getting PR and then throwing it away for sake of few dollars and going above time slotted and working more than allowed and clearly mentioned in your study permit,will be a very childish mistake you will regret whole your life.
So dont make it. Idk which people you are staying with who advice you these things lol but getting PR in canada is a big deal and not a joke and is not as easy as you think even though you are doing masters and can easily apply for it but trust me you will know when you will apply,every single detail is checked .
I went through all this too .
