Having Canadian PR status does NOT remove the restriction on using your national passport to go anywhere or visiting your country of citizenship.Thanks for reply, my friend is also in similar situation as the OP. However, he already got his PR after being a protected person for almost 5 years in Canada. (He is not a Canadian citizen yet). My question is, if he is already granted PR, can he still travel to his home country using his passport?
Only having Canadian citizenship does.
Travelling on your national passport places you "under the protection" of your country of citizenship and also shows that you are capable of being returned to it in the event of being refused entry into another country or deported from it.
