Can't go wrong with WeLeaf. They have the best service, best buds, their shatter looks ridiculous. I haven't tried their delivery service yet, but the fact that they also deliver is great. Definitely the best dispensary in Toronto.
My favourite dispensary, not just because of the convenient location. They have great prices, the staff is cool as hell, very relaxing atmosphere, and high quality bud. Where else can you get a quarter of Girl Scout Cookies for $40? It's a no-brainer.
