Hi wolfpack27616,
First of all hearty congratulations on becoming Canadian PR.
I am 99.99% sure that you will not receive your PR cards before you fly to India, as the PR cards processing times now is 85 calendar days.
So, I strongly suggest you to apply for your travel document so that you can fly back to Canada without any issues. It's very simple process to apply for the travel document. Please take a look at the below provided two links where you will find the complete information about it. I had submitted an application for my travel document on May 13th and I am expecting my passport to be delivered today (as per the tracking information)....don't know whether they have approved my travel document or not....but my original passport is on the way to my home now.
When I applied for it, the VFS official said it takes minimum of 10 working days. Good luck.
