Hi,
I used Canada Post priority pre-paid envelope(National). You can buy it in a canada post office. Here is the link for that. Just make sure you check the signature box. You can buy Express post envelope as well and pay extra money for the signature feature. Up to you. Priority is supposed to be faster. However, due to Covid-19 the next day delivery policy doesn’t apply anymore and the delivery time is not guaranteed.

Canada post Express and priority envelopes, and UPS and Fedex envelopes should be sent the courier address which is,
Case Processing Centre-Sydney
GRANTS Adults
49 Dorchester Street
Sydney, Nova Scotia
B1P 5Z2
If you send it to the regular mailing address, your parcel would be delivered to a postal box, and no one can give you a signature. If you don’t need a signature, you can use a normal envelope or express envelope(without signature feature), and send it to the regular mailing address which is,
Case Processing Centre-Sydney
GRANTS Adults
P.O. Box 7000
SYDNEY, NS
B1P 6V6
The courier address is for the mailing services which need a signature upon delivery, because the picture of receiver’s signature will be provided for you by Canada post. So, express envelope and priority envelope should be sent to the courier address. By the way, if you want to use the express envelope make sure you remind the post officer to include the signature for you for an extra cost. If you use the priority envelope, the signature feature is already included with no extra cost. Just check the signature box on the back of priority envelope. However, reminding them that you need a signature doesn’t hurt.
I don’t recommend mailing such important documents without receiving the receiver’s signature. It completely depends on the budget you’ve considered for mailing your application. However, I strongly recommend the signature option.
