Hi
yes you can, just apply & don't forget to mention it to the CIC office.
Contact CIC regarding your PR application, let them know in writing of your intentions of applying for a work permit.
when applying for the work permit, send another letter to CIC, letting them know that you have a PR application that is still not finalized (include your file/client number##), & that you'd like to use the time available to work, & when done, that you'll leave Canada, but to re-enter as a Permanent resident.
you should have no problem, unless you don't qualify for the job, or that there is Canadian citizen/PR's that qualify better than you for the job you seek. "Ask your future employer to make you a Kick ass letter, saying that whatever qualification he seeks for this job, cannot or is extreemly hard to find in other applicats" (a rare language, a rare experience, or whatever... )
Good luck.
I have no idea what you are talking about, but to work the OP would have to an employer who is willing obtain an LMO (Labour Market Opinion) HRSDC. The employer has to demonstrate that s/he has advertised the position for at least 2 weeks in the job bank, and there are no Canadians or PR available/qualified for the job. Then if the LMO is issued, you can apply at a port of entry for a work permit.
