If everything else is OK, I think they should consider you, not only might. Since the Alberta Immigration Web states:
If the Candidate is exempt from an LMO, you must show you are offering wages and benefits to the Candidate that meet industry standards. Visit the ALIS website for wage and benefit standards in Alberta by occupation.
But anyways. I know 2 people that applied with no LMO (they have OWP), and got their nomination with no further setbacks.
Cheers.
