I was not sure of my plans for next 6 months so I kept a US address as my residential address and my wife's Canadian address as the mailing address. That wasn't a problem for my application. Btw, like you, I also read similar forum posts, and mailed them a "Use of Representative form" declaring my wife as my representative to accept all documents on my behalf. I am not sure if that was required or even accepted; there was no acknowledgement of any sort. But anyways, my package did not get returned.
One problem that I did face recently was when my wife switched her job in Canada and had to move from Toronto to Vancouver and I wanted to
change my mailing address using CIC's form: https://services3.cic.gc.ca/ecas/?app=coa&lang=en. Looks like there is a bug in CIC's portal as the portal won't accept any US residential address if the mailing address is set to Canada (It has Canada fixed as the country choice) . I sent CIC a request, but no response yet.
You may take this into consideration.

I mailed in my application this morning and just my luck, saw a post this afternoon about people getting their applications sent back if the principal applicants mailing address was listed in canada when their residential address is in another country, saying a Use of a Representative form is required. I have seen plenty of posts where this has happened, and I am fully aware it may now happen to me also, but to ease my mind a bit: can anyone chime in whose application was NOT returned in this circumstance?
Thank you!
