The question is whether or not applying for CEC in September would be faster than applying under PhD stream right now. If I was him, I would now apply under FSW PhD stream (you would get an extra 5 points for adaptability, so only 1,950 continuous hours are required from the past 10 years), then, if no medical yet by September, apply again under CEC. But then again, I am paranoid, so not sure if this would be the best path.
CEC is super fast these days (and has always been) compared to FSW. Two of my friends applied under CEC last year after me (I gave them the template of my letters for RA/TA work experience, and they used it, even the wording was similar), and both have already LANDED! It does look like that CEC can be faster than FSW by 4 to 5 months (one of my friends applied on March 2012, and landed by November; the other one applied on May, and got his PR a month ago).
Now, if you have Canadian experience, all you need is just 1 year of work experience, and there is no need to have obtained a Canadian degree (RA/TA, unfortunately, is NO LONGER accepted for CEC)! So by September, you can claim up to 30 hours a week for your work as a researcher (you CANNOT claim more than 30 hours a week for CEC), and if you have 1,560 hours, then you're eligible.
