In 2003 I wrote an article about high gas prices in North America. Here we are about to be in a particular state of 2007 and the price at the pump is vastly higher. This is not a surprising turn of events when we look at all the reasons for the high gas prices we are paying at the pump and on our heating bills.
The usually argued idea by people suffering under high prices is that the oil and gas companies themselves are fixing the pricing system. The majority will find this as reason number one. Most Canadians love to lay the blame on the taxes applied at the pump, and how the oil companies gouge（榨取）the consumers, but they and the media in Canada are ignoring the more important causes.
In Canada, most are unaware that the National Energy Policy, or NEP, has lost its effects partly in the advance of free trade. No longer can the Canadian government try to set up Canadian pricing for oil and gas that is produced and sold in Canada. We completely lost that ability when we signed onto the North American Free Trade Agreement（NAFTA）.
What this means is that Canada now has little control over supplies and pricing within our own country. During the free trade negotiations（谈判）the Mexican negotiators had enough ability to prevent writing the American suggestion into law that both Canada and Mexico must hand over a full two thirds of all of our natural gas production. This leaves Canadians paying world market money charged for something that they themselves export.
Right now Canada ships some two million barrels of oil a day south; yet we cannot do anything about setting national pricing structures, thanks to the free trade agreements.
This is not the whole story though. Even if we were to put an end to NAFTA which is our right under the agreement, we may have already given away too much of our resource. In 1997 there were 41 large Canadian oil companies in Canada. Today there are only six. Of the 35 that on longer exist, U.S. companies bought out 21. This is a disturbing trend of foreign takeovers of Canadian natural resources.
