Sounds fair that you would want regular updates considering you have CAD 227 or even more for the ECA. But, do you think it is feasible to provide regular updates to thousands of applicants every day, considering WES like IRCC is understaffed, and there has been an exponential growth of the number of applicants applying for an ECA through WES. WES used to issue ECA's in 20ish days, but not it takes 35 "business" days, and it's all due to the load.
Some people getting ECA's in 15 days is an anomaly, and those people are very few, like, 1 in 500. And anomalies are a normal thing. Just consider them lucky to have got it in 15 days. That also depended on, from where they graduated, some US/UK and Indian universities make it convenient for WES to verify student and transcripts by providing online tools or solutions like digitary or gradintel, thus allowing faster verification and processing, but many and most of them don't, hence, the time difference.
To WES you pay 220 CAD, to IRCC you would 1125 CAD. Some people get their PPR after AOR in 30-45 days and for some it takes 5 months and for many it takes around 8 months. Why does it happen so? Because, each application, each case is different, so the average comes out to 6 months, but some it harder to process, and some make it easier.
I have waited for almost 9 months to get to the AOR stage, for 9 months I have been dreaming of going to Canada and have been looking at flight tickets for the past 9 months and I have to wait for another 6 months. Trust me, there is no point in fretting over WES or IRCC or BC/IDP and getting frustrated over not getting updates, updates will come whenever they are supposed to come. Getting no updates is a good sign, it means that your application is being processed. You get early updates whenever there is something wrong with your application.
