Here are few things which I can suggest based on my experience and I can understand the stakes here as I am also in the same situation with 14 years of exp.
- Check your probable score using CRS tool and see the scores if that is enough after completing 1 years masters.
- If you think that 1 years masters (3 terms) will not get you enough score, go for 16 months master program (4 terms) and this will fetch you 3 years PGWP.
- Apply to those provinces where the PNP options are good enough for international students. For e.g. BC PNP, Atlantic Provinces PNP, AIPP and so on
- At 35+ with so much of experience, it is not only the admission in a university that matters but Visa should also get approved. Therefore, I would suggest to take up programs which is a leadership program or MBA
Hope this helps!
