congrats! I'm sure you'll make it work.
Here are some links in Toronto that might help:
Food Bank (Daily Bread): http://www.dailybread.ca/get_assistance/get-food.cfm
Help with utility bills (LIEN Program): http://www.oeb.gov.on.ca/OEB/_Docume...assistance.pdf
Low cost spay/neuter (Spaycentral):http://www.getinvolved.ca/member/1022
Animal Control in some areas in Ont are offering low cost rabies shots - they are around $20 I am told.
Sorry I could not find a place that can help you with dog food, but you can certianly ask the food bank or the rescues.
Best of luck to you
