LIMA need for guys who living outside the Canada right? If I'm living in Canada through Pgwp, still do I need LIMA job offer?? And you meant to say, once pgwp finished and if no LIMA job offer, so have to go back to our country? There must be options dude
LMIA isn't just for those who are outside of Canada. It's for anyone who wants to work and who does not meet the requirements for an open work permit.
If your PGWP expires and you haven't yet qualified and applied for PR, then your employer would need to get an approved LMIA in order for you to apply for a closed work permit and continue to live and work in Canada.
Alternatively, you can change your status to visitor if you want to remain in Canada for a few more months. Of course this means you would still need to stop working as soon as your PGWP expires.
There are some people who switch back to a study permit after their PGWP ends and take another full time program in Canada. This is also possible for you however you want qualify for another PGWP once you finish your studies. You can only apply for a PGWP once in a lifetime.
