You need to apply for a work permit. Make sure the LMIA is real before you apply for the work permit or you'll most likely be banned from Canada for 5 years for having a fake job offer.
- If you had to pay money to get the LMIA, then it is fake.
- If the employer offered you free accommodations, food or flights, then it is fake.
- If there was urgency in applying and submitting your documents, then it is fake.
Part of immigration to another country means doing some research on your own. It appears you being a clever person, otherwise you would not have received an LMIA, just go on Google and educate yourself.
