WES: Do I need it or not?

[WandaWits]

I was an international student in Ontario and a PGWP holder. I took my Masters in my home country and graduated more than 15 years ago.
Now that I plan to apply for PR , should I get ECA from WES or is my Diploma program as an International Student here in Canada enough?

Your Masters will give you more points.
