By the way just as a helpful guide for future applicants that require PCC from Mexico you have two options to get it as I just went through the process myself:
1) Go through Canadian High Commission in Mexico - they take between 30-60 days after they receive your complete documents.
2) Get a friend/family or an agent to do it on your behalf.
As I didn't have any friend or family in Mexico I searched like crazy for agents that can do it for me but I faced lots of issues as most of the websites are in Spanish. And when I found some(through Google Translate) most of them didn't bother responding even after repeated attempts. Anyways I was lucky to have found Carlos from "
