I think you should go for it. My parents live in Tanzania and have already got their Indian PCC done through embassy. Here's what I found from the PGP guide,
"
Police certificates
You don’t need police certificates when you submit your complete application.
We ask you for police certificates for the person being sponsored and all family members 18 or older (who aren’t already Canadian citizens or permanent residents) later in the application process.
Police certificates are generally valid for 1 year from the date they’re issued. Depending on processing times, we may ask you for new certificates.
See
how to get a police certificate for up-to-date information about obtaining a police certificate from any country."
