Hello logo...
At the outset, Congratulations man!!
Read your last couple of posts to find out where you are from before I replied to you....you mentioned you were an inland applicant
first why are you referring to everyone here as Sir or Ma'm?...I am not your Sir nor Ma'm...Im just like you my friend-an applicant...

ofcourse you can ask questions-if not me, someone will help...thats what all of us are here for- to help each other
Can the passport be sent from a different address and be received at a different address? Yes
4 possibilities in best to worst order
1. You can goto Canadapost (am aware you are inland and VO is Ottawa-thats where you got the PPR email from), pay them some money and have your mails delivered to new address from old address..this CAN be done if you are moving within the same province.. I think they charge as per package- 1 month, 3 months and so on...but Canadapost has some guidelines-like having your new address on your ID...not a 100% sure..check with them first and do the needful...
2. Update your new address by calling or sending CSE to CIC and move to your new address first...then send passports...you should have 30 days for it to reach them...CSE update should take a week or 10 days max
3. There are different versions of the PPR letter depending on VO...some will state in the PPR letter that "donot write the return address on the return envelope" and some PPR letters dont mention anything about it...if your PPR has nothing mentioned regarding the address then mention your NEW address on return envelope and send...read each word of the PPR letter carefully...if you do as the PPR letter states, you are good-you arent breaking any rules...most of the PPR letters now will most likely state "donot mention return address on return envelope"
4. After you have sent your Passports..you can call or send IRCC webform to CIC and cite some extra ordinary circumstances and have them change to your new address...
Regarding the form you can fill out current address (option 1 3 4) o form and send and update CIC later OR update CIC first and send new address on the form (option 2)- upto you, depending on which route you decide to take...
In either scenario-you will be fine..no complications...
Best wishes!
