Grow your own weed, or, just buy in bigger amounts. A lot dealers don't want to take the risk selling $20's and $40's here and there. I know some people who don't bother with anything under a 1/4. To some, there is just not enough money selling smaller amounts, that's all.

Plus, you're in T.O. It's a big city with a huge cannabis market. I can see where buying smaller amounts would be a problem, but just try to save up some cash, or earn some cash here and there doing little things, and try to buy at least 1/8's from your people, then maybe they won't be so hesitant to bother.

Good luck.
