hi sandrinho,
Just out of curiosity, did you reply to CPC by clicking their email address from the ready for visa email ?
The reason I am asking this because I received the "Ready for Visa" email and in the paragraph of "If you or any of your family members are residing outside North America and you are unable to send your/their passport(s) to Canada and/or to provide a return mailing address in North America, contact us at CPC-CTD-Ottawa@cic.gc.ca so that we can make arrangements to print visas at another office."
when I tried to email them to make a request to change visa office, I clicked the "CPC-CTD-Ottawa@cic.gc.ca" from the paragraph, then my Gmail open compose message with "OttPilot-Immigration@cic.gc.ca" as recipient. I noticed this and immediately added the CPC email address manually. I checked all the CPC email address in the email link to the OttPilot email address. It seems to me that they hyperlink the CPC email address to the OttPilot email address.
I hope this only happened to me.
I got response from the CPC with subject "Ready for visa letter - printing in Singapore" after 6 days.
