Address change online without a copy of fee receipt nor application

[movinouter]

Hello,
I am aware that this kinda question must have been raised before but I can't find the specific answer I am looking for here.
I applied for citizenship in Oct, 2018 in Calgary, AB but I might have to move to another city within AB after winter. I know there is an online request available but they state that I may need documents related to my application, including one or more of these:

• a copy of your application
• your fee receipts
• any letter or official document we issued to you

Well, I printed my application straight from the library printer because I don't have a printer myself and so is the case for the fee receipt. So I have no copy of either of them.
In this case, how can I change my address online? Can I use the Web form?

Any advice/help would be highly appreciated.
Thank you.
