Again, if I understand correctly—I'm very sorry that maybe my distance doesn't allow me to understand—you're talking about what we produce and what we export or use locally. Am I right that you are asking this? Canada is a major food exporter. Canada also has no problems concerning the availability of food, but in certain areas Canada's food is very expensive and not affordable.
If we go to the more remote areas, Canadians spend extreme amounts of money on food you can easily get more cheaply. Of course, price is a market issue, based on demand and supply. If there is not much demand, sometimes the prices can go very high. If there's no available food, then the price goes high.
Of course, these things should not be completely dealt with by market forces, because food has become more of a global common good. I'm not saying government should be giving food away for free, but that they should be able to regulate to protect self-sufficient agricultural policy for Canadians while they are thinking about exports.
