Help my family coming from Fort Mac

On May 3rd 2016, a wildfire began to burn out of control in Fort Mac since forcing upwards of 88 thousand people from their homes. Many people have lost everything they have, and many are waiting to find out if they have a home to go back to (whenever that may be..).
Evacuees fled to camps where they are now being evacuated from once again. 
My sister Hollie and her two kids, Alexa (6) and Andrew (5) were staying in a camp and are now being flown out to either Calgary or Edmonton. Once there, they do not know if they will have anywhere to go. We would like to fly them back home to Ontario until it's safe to go back to their home (if they still have one). Unfortunately, with the little amount of warning to evacuate - she was only able to grab a small amount of their things and leave. 
I am asking for ANY amount that can help towards the flight, food, clothes, all necessities, etc. ANYTHING will help. We do not know how long they (and the rest of Fort Mac) will have to wait before they can go back to (hopefully) their home(s). We just want to make this waiting period as comfortable as possible.

Please. If you have even $5.00 to spare, it will help.

Thank you!!
