Yeah I have seen few 1-year Masters program, but most of them are not accepting a gap more than 7 years.
There are few programs which are very expensive seeing my pocket, so I have to see everything at every end.
Hope you understand my situation.
Now that's new, a Bachelor + a PG Diploma + 7 years experience, your chance to get a study permit with that Graduate Certificate is tiny. Going to Canada and taking Higher Education definitely cost money but it takes what it takes and it is not negotiable. Good luck then.
