Well, assuming (albeit one that would definitely create a huge uproar) CIC's strategy is to slowly drive out all open work permit holders like PGWP, etc. (as they do not originally require LMIA) and bring all those jobs (probably a really huge number) under the radar of the job bank. Employers would now post these jobs on the job bank and more Canadians would have access to all those new jobs created by the void left by open work permit holders. As they start to apply for these job positions, employers will try matching the maximum number of Canadians with those jobs and the rest for which they could not find one, they will try finding a close match from the applicants in the pool, based on education and skills (score based) and probably an interview. Based on its outcome, they will be granted an LMIA based on employer's recommendation to ESDC. Atleast that seems to be CIC's possible intent behind the whole express entry thingy.
