How are you getting $10-15/day per person per day for food? If you're eating a lot of prepared foods and/or at Tim Horton's every day, that sounds about right, but if you are smart about the grocery shopping, estimating from US prices which I think are comparable to Canada's in absolute dollar terms, I think $500/month should be doable for a family of 3. At least in the US, there are discount grocery stores around, and even big grocery stores have sales as well as their own cheaper store brands for products. In many places, there are also farmers' markets that sell fruits and vegetables and sometimes even some meats for cheaper. And if you collect higher dollar value coupons and use them to stock up when the grocery store is also having a sale on those items, you can save a lot.
