They might or might not. Not consistent. Some people have received an email saying the document they submitted has been noted. Some didn't receive. I didn't receive any acknowledgement for my ECA.MZASAM said:
Maged: Done. Ordered WES/ECA for me and dependent and sent a mail to ontarionominee@ontario.ca and expressentry@ontario.ca.
Thanks indeed for your concern. Highly appreciate
Though Bestofluck left to my decision; I went ahead ..
Will OINP acknowledge the receipt of duplicate reports?? Anybody!!!
Also, as of now, nobody is waiting for them to ask - it'll just delay the application. No point. So IMO, it is better to submit it upfront.
