Howdy!
Since the whole idea behind eating your hamburger in an alley is to increase the number of Twitter followers for a restaurant, I figured you might be interested in knowing about other Canadian burger places on Twitter.
In no particular order:
Fatburger Canada, The Works, Jukebox Burgers, Le Boucan, Brasserie T!, Jolifou, m:brgr, Johnny eh's!, Depanneur Le Pick-Up, lanecdote, New Palace, Bunman, nimby burger, Le Gourmet Burger, DicAnns, Lawrence, and the one, the only the inimitable Mr. Lew's Great Burger Search (if you're only going to follow one, he's the one to follow).
Who did I miss?
