lots of places.
One of my fav tabacco shops is in dufferin mall. Not insanely fancy, but they always have some nice cohiba's/montecristo's in various sizes, as well as a very good selection of medium priced cigars (I usually smoke Romeo Y Julietta #3, i forget how much they are for a box of 10, but considerably cheaper than where i bought em before).
Its called (sanford?) and sons smoke shop.
p.s. buy cubans.
