Hi Scylla,
Thank you for your response. Even though I am older, I am a veterinarian and think that I may have enough points to qualify for some of the programs that I have reviewed on the Canadian Immigration website. But, maybe I am totally wrong on that point. Granted I won't get any "bonus" point for my age!
Sorry - I missed the fact that you may be able to claim points for Canadian education. That should help. I would run the numbers all the same before renouncing your PR status. Also keep in mind that immigration programs change so what is true today may not be true in a year.
