if you'll be traveling around the city, get a monthly metro pass. they're like $110+taxes, and the pass gets you discounts at most of toronto's major public attractions (ie: the science centre, the zoo -although the zoo is allt he way in fucking scarborough, and scarborough is faggotsauce-, among other places.)
should frequent redflagdeals.com if you're not aware of that site. check their hot deals section among others, can find deals on all sorts of shit all around the city. lot of the deals are primarily toronto, although you might see shit pop up fr om like vancouver or something.
after your rent, budget at least another $350 for travel, food, maybe eating out 1-2 times a week. Then add on howeve rmuch you think you'll be spending on other shit. Maybe you buy clothes are something (even though buying clothes here int he city is stupid as fuck, since you can get anything online for half the price that local shops charge you for it.)
hit up kensington market often. get food ont he cheap. and if you dont mind chinese food, the best spot to visit is king's noodle at spadina and dundas. order a plate of yang chow fried rice, which is a GIANT plate for like only 6.50!
hope that helps :P
