Congrats on getting your permit.
I got an email from CIC requesting my original travel on august 7th and submitted my passport through VFS Global on August 8th and I got an email with this subject line: Application Received/Demande reçue - Canada Visa Application Service <donotreply@vfshelpline.com> and they gave me a tracking number and told me it was 5 to 7 business day to get my passport back.
I am mexican national
Hope this help
Good luck!!
