NO。。。。 If your residential status has not been changed from a student to a immagrant, ur Study Permit is ur only valid proof that allows u to be staying in Canada. When the study permit is expired, which is the case u are in, staying in canada turns into illegal, regardless the visitor visa expirs or not."Losing ur status",it is called. Do not show up at any place that might requir ur Passport to be cheacked, if u really intend to stay. Find a lawyer and spend a couple grand to get ur status back. GOOD LUCK.
Finding a way to stay is the intention of the most, we've got to TRY...
