Methi - Fenugreek leaves
Sami Fruits at the Jean Talon Market used to have it on a fairly regular basis. Unfortunately, that store has closed. Don't know about their other outlets.
Am pretty sure I've run across it at Marché Victoria Oriental (6324 Victoria, 514 737-4715) or maybe nearby Epicerie Shavit (6334 Victoria, 514 739-4403), both near the Plamondon metro station. (Both definitely have the dried leaves.) Probably best to call and ask before making the trek.
