Hello,
I sent my documentation to request the police certificate since February and yesterday I received an automatic reply.
Mexico has officially declared the coronavirus pandemic a national public health emergency, suspending all but essential activities in the private and public sectors and asking the population to stay home. Accordingly, the Migration section of the Canadian Embassy in Mexico City is currently working with essential staff only and providing essential urgent services through teleworking.
Issuance of police certificates by the Fiscalía General de la República (FGR) is not an essential service, therefore processing has been halted until further notice. Regular services, including the process of FGR certificates, will resume when restrictions are lifted by the local government.
No application in progress will be closed or refused because of documents missing due to COVID-19. We’ll automatically give you 90 days to complete these steps.
You can monitor the situation on IRCC website
