Help Alyssa, Rachelle and Noella get a Fresh Start

My partners nieces (Ages 3, 8 and 13) suddenly came into our care after the Children Aid Society dropped them off. Due to it being the third time they have been removed from their mothers care we believe they will be remaining with us for the time being. Due to the pandemic the process is especially slow, all we have received is food cards just once. We have a link to other resources that may help but we won’t seeing that for a while.
Their mother is able to help sometimes as the Childs government financial benefit is still under her name, but there’s a delay for when/if it will be transferred.
We are moving to an apartment that can accommodate their needs a bit better while we figure things out. We're saving first and last months rent for this apartment but may need to get them a bunk bed (depending on wether Children’s aid society is able to provide them) as they have been using ours in the meantime, and dresser for all the clothes we managed to get donated. We also need to finish baby proofing the house as the three year old is still clumsy, books for the 8 year old as she’s very behind on reading; clothes for the 8 year old as she barely has any.

Hope you can help us in a tight bind. We love these girls and want them to have the best possible upbringing while they are in our care.
