Hi, sorry I haven't answered before now, and you may not like it much, but here I am...
How long a pmq takes is dependent on a lot of factors... different bases take different amounts of time. If you have kids, that can affect it as well. I know in 2006 in Borden, there was sometimes a 6 month waiting list, after you submitted the paperwork. In Trenton, I was approved and moved into a Q within a month and a half. I don't know what the averages may be, but the best thing to do would be to get a hold of the CFHA wherever you're getting posted, and ask them what the general wait time has been looking like. That's the best suggestion I can give you. Sorry I couldn't do more!
