I've seen and purchased all the meatless products from Schneider's (meatballs, chicken burgers and chicken nuggets) but by far the chicken burgers were the best. Did they dis-continue them? I usually saw them in Safeway. (Delta, BC)
Haven't seen these anywhere myself, but I'd recommend using the contact link at the bottom of the page to send a message or call the listed customer service toll-free number - they can probably quickly tell you if anyone carries them in Montreal. Good luck!
