PMM is right, it doesn't make sense for you to have applied as a skilled worker having a Canadian wife. Your wife would have probably suspected this when you applied, so perhaps you can clarify that.
But since you already applied, you can check the approximate times here: http://www.cic.gc.ca/english/information/times/index.asp. (But I assume you already know that, too.)
