If you want to do it legally, you need to do some hunter safety stuff (not sure what that's like in Ontario) and start acquiring gear.
The biggest expense for you because you're in the middle of Toronto is a vehicle. It should be a 4x4. You're going to need it to get out to the bush. You've already blown your monthly grocery bill out of the water in insurance, fuel and urban parking costs.
Next you need weapons. If you want guns you'll need to get your PAL which is about $280 after course fees and paperwork, and you'll have to wait awhile to get it. While guns are hands down the most efficient way to take animals, they have an expensive downside in that rimfire rifles aren't legal for big game, and centerfire rifles blow up small game - generally hunters end up buying a few different guns at least.
A cheaper and faster way would be to get a compound bow. The upside here is that one bow can be used for many different animals, access to hunting spots in agricultural or even some suburban areas is much better, you usually enjoy expanded or extra seasons, no paperwork is involved and finding places to practice with your bow will be easier. The downside is that you'll need to practice far more to be effective, and no matter how good a shot you become you will spend a lot more time in the field for each animal you kill. Arrows are expensive but still cheaper than frequently shooting centerfire rifle ammo.
There's a lot of peripheral gear involved as well that changes depending on how you hunt. Can be cheap if you're after small game on agricultural land; can be very, very expensive if you're chasing big game in the bush on crown land.
Also, to counter all the bullshit suggestions to poach: You'll get fucked, hard. CO's will confiscate your gun/bow, all your camping gear and your vehicle; then you'll have to go to face whatever fines they want to impose.
