How long are your planning to be in Canada after you receive your PPR?
If your application is being processed in India office, then the PPR will come from Indian office. If you are still going to be staying in Canada for a month or two after receiving PPR, then you can inform them about your location. Then they will send a separate PPR from Canadian office for you and from Indian office for your dependents. You can then separately send your passports to respective Visa offices.
