Where can I find Ration Pack in Quebec( MRE )?

I would like to buy Civilian or military MRE. I always eat out and it cost me about 15$ a day in junk food. MRE would be great as I could carry the meal with me and just eat it on the run. I would like to spend less then 9$ for each MRE. I can order from Internet but I would prefer to buy it in a store. Thank you!!
