On the email I got yesterday (the person who got my call sent me) had three addresses. Here folows what's on the email:
Here is the address to use if you are sending your photos by regular mail:
New permanent residents (if you are waiting for your initial card):
Case Processing Centre - PRC
P.O. Box 4500
Sydney, Nova Scotia
B1P 6L1
OR
Existing permanent residents (e.g., PR card replacement):
Case Processing Centre - PRC
P.O. Box 9000
Sydney, Nova Scotia
B1P 6K7
If you would like to have proof that your photos were received, you can use registered or express mail with Canada Post or a courier service such as Purolator, UPS, FedEx, etc. Please instruct the courier service to use the address listed below:
Case Processing Centre - PRC
49 Dorchester Street
Sydney, NS
B1P 5Z2
Since I sent by UPS, I used the last address. Come to think of it, I should have sent to the PO Box for new applications, maybe they check that more often or something. Well, there's nothing I can do now
