Family with moving expenses

Hi, my name is Rowan, I have 4 wonderful children and my landlord is not renewing my lease which honestly is a good thing. The place has chronic plumbing and electrical issues and is not a safe environment for my children. I have thankfully found a place to move on short notice but given that it is such short notice I'm struggling to come up with the first months rent and damage deposit as I will be moving at the end of the month and I will still have to pay rent at the place I'm currently at. With the current rental market I'm lucky to have found a place I can afford and I can't pass on this opportunity and risk becoming homeless. Hurricane Fiona wiped out any funds that I have saved and I still haven't been able to access the red cross funding. Any help would be greatly appreciated.
