Quetions about moving

Didn’t know what tag/flair to put this under, but, my current OW payment is 733 a month, for renting a room off someone.

My partner and I have found a 1 bedroom apartment for 1800 month, she makes 4200ish a month, whilst my only income right now that’s on the books and not the occasional cash job, is OW.

How do I go about changing my address to my new address, without getting my entire OW payment screwed over? I’m pretty reliant on it until my ODSP comes through.
