There's a whole bunch of requirements your employer needs to meet for the LMIA. First he needs to advertise the job for at least a month in three different locations that meet the LMIA advertising requirements (this is to prove that no Canadian could be found for the role). Yes - he needs to show what salary he will be paying you (this information also has to appear in the advertisements) - and this salary must be at least the median wage for your occupation in your province (otherwise the LMIA will almost certainly be refused). There are a number of other requirements to the LMIA process - your employer will have to research the process to understand what's involve. Processing of the LMIA application can often take 2-4 months with no guarantee of approval.
