I'm not sure what income tax is here; mostly because of school I actually get more in a return than I pay (and due to me not working while in school and thus having a low income under the personal allowance). This year will be a shocker, though... which reminds me, I need to get my shit in order and file my 2011 taxes...
In Ontario, our sales tax is 13% (which has gone down) and we don't get changed any tax on basic food items anymore (with some exceptions, I'm sure). I haven't driven much since I moved downtown, but I think gas right now is around $1.20/litre, I usually spend $8-12 at McDonald's, and the rend for my (2 bedroom, 2 full bath) condo is $1795/mo. I'm not sure what our national average salary is, either, but I'm a little shy of $40K/year as a Junior Designer.
Not too bad, really. No complaints. Anywhere else in Canada is cheaper to live, too... except maybe Montreal, Vancouver and Calgary IIRC.
