Actually, yes. However, BC LMO processing is not so fast. In case of rosjana16, it was damn fast(may be he is lucky). Generally, it takes about 16-20 weeks in BC and as rightly mentioned by you, Alberta processing time is faster compared with BC.
For ex, I am waiting for the LMO result which was applied on April 9th (NOC - 2174 Skilled - A category). SC contacted employer only once(around May 1st). There are people in this forum who have been waiting for LMO for almost 20 weeks. I guess, the processing time depends not only on province but also on NOC.
