At least here in Canada, where health insurance is generally not needed and minimum wage is around $10/hr I think it's quite reasonable to live on minimum wage, if you are careful. I wouldn't want to do so forever and I wouldn't own a car and might have to have a roommate. But it's doable.
I'd assume a rough take home pay of $1300. And here are some numbers from my own current expenses:
half of rent for 2 BR: $500
half of hydro: $35
half of phone service: $50
half of internet: $30
laundry: $15
bus pass: $80
food: $300 (this is my real cost; you could get lower obviously)
Total Fixed: $1010
Remainder of $290/month for clothes, miscellaneous, savings
Of course if you want to drink, smoke, shop or eat out it gets a lot harder.
