How did you get the confirmation? is it by email or on your profile? I have everything ready to submit but I don't know if I should wait to get a confirmation or if that is going to show up automatically in the system.
I emailed the Canadian embassy in Mexico city asking if they had requested the Police letter to the Mexican authorities yet, and a day later they replied saying they sent the request to the Mexican authorities on "X" date. You have to ask them by email, they usually reply within 24 hrs.
