If this is the case then they will never give you ECA with Canadian Masters Equivalency.
WES attitude towards Pakistani Degrees and I should say that in general towards whole Pakistan is discriminatory.
For my case, I was able to get Equivalence Certificate from HEC that my Masters degree is equivalent to M.Phil of Pakistan and it is equivalent to 18-years of schooling. HEC have provided me this certificate in sealed envelope and assured me that WES will consider it equivalent to Canadian Masters degree. I sent this sealed envelope to WES through DHL courier. HEC also assured me that this is prevailing practice in Canada to declare Pakistani MPhil degrees equivalent to Canadian Masters degree. But WES remained stubborn to their point of view that if you will not do PHD from Pakistan, rest of Pakistani Degrees will remain equivalent to maximum Canadian Four Bachelor Degree. That is really discrimantory attitude towards Pakistan by the staff/officials sitting in WES.
Even I have done myself online research in this regard and find out that several Canadian Government departments and Canadian Government Universities declare Pakistani MPhil(18-years of schooling) equivalent to Canadian Masters Degree. Even the IQAS which is competitor of WES, declares Pakistani MPhil degree equivalent to Canadian Masters Degree. I have submitted to WES, evidence from 10-Canadian Government sources and from the official website of those Canadian Government sources and the web addresses, where this evidence is mentioned. This list of evidences also included one of the competitor of WES, which is IQAS. IQAS is also Canadian Government of Alberta qualification assessment department. Even CEC (Comparative Education Services) University of Toronto is considering 18-Years of schooling of Pakistan equivalent to Canadian Masters.
I even got another evidence from the WES free assessment tool.
In that tool they have not listed Pakistan. Therefore I selected India and selected MPhil degree of India. The result of free assessment tool was "Indian MPhil degree" is equivalent to "Canadian Masters degree".
Here you can clearly observe the discriminatory attitude of WES against Pakistani Nationals and Pakistani Qualifications. Despite of the fact that both India and Pakistan inherited the same education system from Britain they have declared Indian MPhil equivalent to Canadian Masters and Pakistan MPhil they did consider equivalent to Canadian Masters. Second discriminatory attitude is that they did not even include Pakistan in their free assessment tool's list of countries.
I shall strongly urge you to officially launch your complain against gross discriminatory practices of WES against Pakistan, through the Better Business Bureau (BBB) following website link, where others are filing their complaints against WES and getting relief.
