The Individual Meal Pack or IMP is one type of field ration used by the Canadian Forces. The IMP is designed so that a continuous diet provides all the nutrition needed to sustain a soldier in the field. The IMP meets Canada's nutrition requirements, with the exception of calcium and folic acid, which are not significant if the consumption period of rations is less than 30 (consecutive) days. IMPs will provide 1200-1400 calories per meal.
Contents of the combat rations are subject to a three-year research and development cycle, where new meals are added, and some replaced. Every second year, new meals are field tested by three groups of 60 persons drawn from each of the three Canadian Army brigades. In all, there are 21 meals available broken up into two categories of seven breakfasts and 14 meals suitable as noon or evening meals. In addition to the main meal, each IMP contains assorted basics such as powdered coffee, protein and sports drink mixes, energy bars, trail mix, peanut butter, cereal, condiments, candy, chocolate, gum, a plastic spoon, a wet towelette and matches.

Requirements
Three IMPs (breakfast, lunch and dinner) provide approximately 3,600 calories (15 MJ), enough to nourish a soldier undergoing strenuous physical activity. The meals are precooked and can therefore be safely consumed either heated or unheated. Under ideal circumstances the entrees are generally consumed heated.

Other rations
Other types of rations are used by the Canadian Forces, notably fresh rations, or cooked meals provided directly from the kitchen or by Hay Box. There are also patrol packs, which are small high-protein snack-type foods (such as beef jerky or shredded cheese) and boxed lunches (consisting of assorted sandwiches, juice, fruit, pasta and a dessert) provided for soldiers to consume in situations in which meal preparation nor the delivery of haybox style fresh rations are not possible, such as travelling for training within Canada or spending the day on a shooting range. The IMP is intended to be issued when fresh rations are not possible, they can also be consumed as emergency rations, unheated.
History
The IMPs appeared in the Canadian Forces in the 1980s, replacing early canned rations (Individual Ration Pack (IRP), Canadian Army Mess Tin Ration, Compo rations). The main menu items of the IMP are "boil in a bag" (known as a "retort pouch") and require less preparation time and equipment than the previous canned rations. Another stated advantage is that preparation using retort pouches can be done using less heat, reducing the impact on the taste of the food.
Preparation and cooking
For IMPs, the main entrée and the dessert portion are contained in retort pouches, which are then packaged in cardboard boxes. These cardboard boxes are positioned inside the IMP package on the outer sides, sandwiching the other contents, so the IMP itself looks like it is entirely contained within a cardboard box inside the outer foil-lined paper bag. IMPs are usually "stripped" before field use by removing the cumbersome packaging and discarding extraneous elements individual soldiers do not wish to carry with them, such as the cardboard boxes containing the main entrée and dessert, and any condiments that an individual soldier may not personally use.
The new method of heating has greatly improved over the previous options. The soldier simply puts their meal packet into a flameless ration heater. The chemical reaction generates enough heat to ensure a hot meal.
Meals are packaged fully cooked and do not require cooking. While edible cold, when circumstances permit the ideal method of preparation is to cook the entrees in a pressure cooker, heated on the standard issue Coleman stove, or by simply boiling the rations in its package in water. Another way to warm the meal when a stove is unavailable is by putting it in the pocket of a coat during winter. Chemical cooking pouches have also been issued, allowing for flameless meal heating. Other items can also be improved by boiling or adding water, such as packages of soup, rice, powdered drinks and even the prepackaged bread, which is dense and can be softened by exposure to the pressure cooker.
Another technique developed by soldiers in the field is putting the package in the grill covering the exhaust on many armoured vehicles, and on radiators of wheeled vehicles. Some armoured vehicles come with a built-in pressure cooker.
