There's at least one place that I know of, which is in the Etobicoke area (on Dundas St.)...I drive by it every day on the way to/from work. They have 100% grass-fed beef and free-run chicken, among other yummy things.
I'm dying to try KerryGold butter, though...and am thinking of a drive to Buffalo. lol
Also been thinking of ordering a portion of a grass-fed cow but that meat wouldn't be delivered until July or so. Ahem...CHA-CHING!!
