The Canadian rations can be hard to get.

I might know of a place I can get them from but selection varies.

Canadian rations (IMP) Individual Meal Package) are pretty good.
Each year has 6 meals of Breakfast, Lunch, Supper (18 different meals) packed 10 meals to a box.

IMP's expore 3 years after the date of packing.
So 2008 menu expire in 2011 but there still good for 5-7 years after if stored in a cool dry location.

I have 25 galons of water, and about 70+ Canadian IMP's.
Various breakfast, Lunch, and Dinners, most are 2008 menu.

I have a case of US MRE's coming soon, and im getting more IMP's next month.

Anytime.

This is my first attempt at posting pics and a review. I just opened and tried a.... Canadian Forces Food Packet, Light Meal Combat (LMC) 2008 Menu No.4- Beef Jerky, Teriyaki Flavour. The package. 004.JPG The contents 008.JPG 250ml of water and 1 pack of drink mix (Ice flavor gatorade) 016.JPG 017.J...

There is a company in Canada that has a huge selection of Mountian house priducts.

Finding US MRE's is not that hard I have a few sources for them.
Canadian IMP's are a little harder to find, but I can get them as well, the best I have seen so far is 2009 menu.

I also found one place that has LMC (Light Meal Combat) but there few and far between.

Ive heard of these, I dont remember where, but Ive been meaning to try them.

3 years is the "expiery date" but rations are said to be good for at least 5-7 years after that date.

Mind you if there stored in a cool location then there should not be much of an issue, there might be some flavor loss from what I hear.
