http://www.cim.mcgill.ca/~jer/visit/rest.html Jeremy & Vinita's Montreal Restaurant Guide (thanks to seabound for the pointer!)
http://montrealpoutine.com/ The ever-opinionated guide to poutine in the city.
http://www.midnightpoutine.ca/ is more an city arts, music, and film blog, but it occasionally does food, and has an amusing series called Metro Roulette, where they send a blogger to write about a random Metro station and its surrounding neighborhood.
