Unfortunately, you will have to do at least 200 hours more since it's been more than 5 years since your last flight. As of today, the only flight time that will be counted for issuance of your DGCA CPL will be any flights flown after 14/10/2008. Since all your flying was done before that date, it won't be considered for issuance of the CPL. If you do plan on flying for 200 hours more, remember that you will also need 100 hours PIC, 50 hours cross country, 40 hours Instrument etc within those 200 hours.
Another thing you have to keep in mind is that your DGCA papers are about to lapse as well. As per the latest rule change, all DGCA exam results are valid for 5 years(used to be 2.5 years before). So your papers will lapse in 2014(depending on when you passed them in 2009). So if you do plan on flying all these hours, you need to make sure you finish them and submit your application before your papers lapse, or take your exams again. Same thing applies to your RTR(P). Check the validity period on that license. And goes without saying that you also have to renew your Canadian and DGCA first class medicals.
The DGCA also made a new rule last year that requires all pilots to do at least one set of skill checks in India(if you are getting both Single and Multi engine endorsements on your CPL, skill checks for at least one of the endorsements has to be done in India). So even if you do plan on completing the required hours in Canada, you still need to fly your skill checks in India.
Best of luck!
