Thanks to everybody.
As I mentioned it, this a very common an specific step for all Mexicans. We usually submit LOCAL police certificates with our application, but those police certificates are from our home state(province). Later on, Canada immigration always request Federal police certificates for us. They even have an specific procedure for that, but this is just for Mexicans.
I also know, that almost right after police certificates requests, Mexicans normally get medical requests. Usually a few days, or a couple of weeks after.
I will keep you posted if i get a medical request.
