Change of LMO for Existing Work Permit Application

[chelsea]

Hi everyone! I have this dilemma. I already applied for Work Permit for LMO which I got in Alberta. It's one month on the go.  But I recently got another job offer and I am already in the possession of LMO for Ontario now, which has a good offer compared to Alberta.  What do I do? Do I need to withdraw my on-going work permit for Alberta? Or will I just send to the CIC the LMO for Ontario and it will automatically cancel my work permit in Alberta application? 

Please help...Thank you and any advice will be much appreciated...
