Just though i would add.
My firm applied for my LMO on April 9, 2014 in the Noc A category in BC. The got the confirmation i think April 29 that it was received and they got the positive LMO on June 13,.2014.
This is my 3rd LMO for this job and this time was much harder than the previous ones. We almost got knocked back because m'y firm used their in-house job vacancy for one of their advertisements and because of contraction in my industry they received a lot more resumes that were close to qualified on the past.
I do, however, bring quite a bit of revenue into Canada and Canadians get directly compensated from the business i bring in.
So our process was 2 months
